City Water and Light to Develop Arkansas Solar Energy System

City Water and Light (CWL) and TurningPoint Energy (TPE) have partnered together to develop a solar power system totaling 13.25 MW in Jonesboro, Ark. 

The system marks the first solar power project for CWL, affirming its commitment to bring clean, cost-effective solar power to its customers and community.

The solar system will be developed and constructed as a turnkey solution by TPE, a clean energy development company that works with utilities to customize solar projects throughout the U.S.

Construction is planned to begin during the summer of 2021, and the system should be operational and generating sustainable energy for CWL electricity customers by December of 2021. The solar power system will support 125 jobs in Arkansas in the form of consultants, engineers, construction and related workers. CWL will own the system, which will generate an estimated total of 24,292 MWh during the first year of operation. 

“With the impending cease to use coal dates of 2028 and 2030 for our coal plants at White Bluff and Independence respectively, this resource will be a great addition to our generation portfolio,” says Jake Rice, manager at CWL.

“It will provide sustainable energy and price certainty for our customers for many years. We are excited to partner with TPE to bring solar-powered energy to our community,” he adds.

CWL has coordinated closely with TPE to conduct preliminary site feasibility studies to ensure an optimum location. After a rigorous site selection process, the system is planned to be located on approximately 98 acres near Nestle Way and Great Dane Drive.

“We are honored to partner with CWL to provide a turnkey solar solution from development to construction to operation for a clean, seamless generation resource within the CWL portfolio and its community,” says Jared Schoch, president of TurningPoint Energy.

“Now it’s time to deliver on the commitments we have made by bringing the best solar industry providers to Jonesboro to actualize this project,” adds Schoch.

Falling LCOE of Solar Puts Existing Coal, Gas at Risk

Solar PV and onshore wind are now the cheapest sources of new-build generation for at least two-thirds of the global population. Those two-thirds live in locations that comprise 71% of gross domestic product and 85% of energy generation. Battery storage is now the cheapest new-build technology for peaking purposes (up to two-hours of discharge duration) in gas-importing regions, like Europe, China and Japan.

The latest analysis by research company BloombergNEF (BNEF), Bloomberg’s primary research service that covers clean energy, advanced transport, digital industry, innovative materials and commodities, shows that the global benchmark levelized cost of electricity (LCOE) for onshore wind and utility-scale PV has fallen 9% and 4% since the second half of 2019 – to $44 and $50 per MWh, respectively. Meanwhile, the benchmark LCOE for battery storage has fallen to $150 per MWh, about half of what it was two years ago.

Onshore wind has seen its most significant drop in cost since 2015. This is mainly due to a scale-up in turbine size, now averaging 4.1 MW, and priced at about $0.7 million per MW for recently financed projects. The best-in-class onshore wind projects can achieve an LCOE of $24 per MWh, the lowest globally. Meanwhile top projects in the U.S., India and Spain follow at $26, $29 and $29 per MWh respectively, excluding subsidies such as tax-credits.

Globally, BloombergNEF estimates that some of the cheapest PV projects financed in the last six months will be able to achieve an LCOE of $23-29 per MWh, assuming competitive returns to their equity investors. Those projects can be found in Australia, China, Chile and the U.A.E., where they will challenge the existing fleet of fossil fuel power plants.

“There have been dramatic improvements in the cost-competitiveness of solar and wind. Part of it is due to photovoltaic and wind technology getting better at extracting renewable resources,” says Tifenn Brandily, lead author of the report at BNEF. 

“But our analysis also suggests that since 2016, auctions are forcing developers to realize cost savings by scaling up project size and portfolios. Larger scale enables them to slash balance-of-plant, operations and maintenance expenses – and have a stronger negotiating position when ordering equipment,” adds Brandily.

Globally, BNEF estimates that the average onshore wind farm has doubled its capacity from 32 MW in 2016 to about 73 MW today. Solar farms are a third more powerful today, at 27 MW on average, compared to 2016.

Battery storage is another example of how scale can unlock cost reductions. BNEF estimates that the average capacity of storage projects sits at about 30 MWh, a fourfold rise compared to just 7 MWh per project four years ago. Since 2018, increasing project sizes combined with a rapidly expanding manufacturing base and more energy-dense chemistries, have halved the LCOE of energy storage.

“The coronavirus will have a range of impacts on the relative cost of fossil and renewable electricity,” says Seb Henbest, chief economist at BNEF. 

“One important question is what happens to the costs of finance over the short- and medium-term. Another concerns commodity prices – coal and gas prices have weakened on world markets. If sustained, this could help shield fossil fuel generation for a while from the cost onslaught from renewables,” he adds.

Chinese coal miner starts work on world’s biggest green hydrogen facility

Baofeng Energy appears to be switching its focus to hydrogen production and says its new project will be powered by two 100 MW solar plants and will start producing 160 million cubic meters of hydrogen annually from next year.

Chinese coal miner Baofeng Energy has announced the start of construction of what it claims will be the world’s largest solar-powered hydrogen plant, in the Ningxia Hui autonomous region of northwest China.

The RMB1.4 billion ($199 million) electrolysis project is intended to produce 160 million cubic meters of hydrogen per year plus 80 million cubic meters of oxygen. Baofeng said the use of solar electricity to power the facility would save 254,000 tons of coal consumption annually, leading to a 445,000-ton reduction in carbon emissions.

The project will feature two 10,000m3/hr electrolyzers powered by two 100 MW solar plants plus a 1,000kg/day hydrogenation station and two petrol stations will be converted to also supply natural gas and hydrogen for transport purposes. The solar panels will be installed over wolfberry and alfalfa crops which will generate extra revenue, according to Baofeng.

Work on the project started this month and is slated for completion this year, with hydrogen production to start next year.

Baofeng is also working on a coking co-generation plant to produce three million tons of coal-based coke per year, plus 1.2 billion cubic meters of hydrogen.

LCOE from large scale PV fell 4% to $50 per megawatt-hour in six months

Analysts at Bloomberg New Energy Finance say the lowest-cost projects financed in Australia, China, Chile and the UAE in the last six months hit a levelized cost of energy of just $23-29/MWh and the best solar and wind projects will produce electricity for less than $20/MWh by 2030.

The cost of generating solar power has plunged low enough to threaten thermal power fleets in the world coal capital of China and fossil fuel facilities in the petrostate of the UAE, according to new figures published by Bloomberg New Energy Finance.

With the crucial falls in the levelized cost of energy (LCOE) from large scale solar and onshore wind having occurred in the last six months, the analyst also claims energy storage projects are now cheaper in Europe, China and Japan than building new fossil fuel facilities for handling peak electricity loads – with the switch having taken place over the same period.

The average levelized cost of energy (LCOE) generated by large scale solar plants has fallen to $50/MWh since October, according to the BloombergNEF study. That marked a 4%, six-month fall in costs for solar, according to the analysts, during a period when onshore wind costs tumbled 9% to $44/MWh.

The roll-out of monocrystalline solar modules in China drove down the solar power cost 9% to $38/MWh in the global solar capital during the same period, said BloombergNEF, with the study adding: “New-build solar in the country is now almost on par with the running cost of coal-fired power plants.”

Stranded assets

Fossil fuel plants in Australia and Chile as well as China and the UAE could be put at risk, according to the Bloomberg study, as the solar power cost from big projects over the last six months in those markets has hit US$23-29/MWh.

And the solar price falls are set to continue, according to BloombergNEF, with analyst Tifenn Brandily adding: “On current trends, the LCOE of best-in-class solar and wind projects will be pushing below $20/MWh this side of 2030. Today, the best solar projects in Chile, the Middle-East and China – or wind projects in Brazil, the U.S. and India – can achieve less than $30/MWh. And there are plenty of innovations in the pipeline that will drive down costs further.”

On energy storage, Brandily said batteries had forged a more convincing business case than facilities such as gas peaker plants which could be quickly fired up to help meet surges in electricity demand. “The benchmark LCOE for battery storage has tumbled to $150/MWh, about half of what it was two years ago,” said the analyst.

That was chiefly down to rising sales enabling storage manufacturers to drive down balance-of-plant and operations and maintenance costs, according to the analyst.

Duke Energy Progresses Toward Climate, Sustainability Goals

Duke Energy has released a pair of data-driven reports outlining the company’s recent accomplishments and path to advance its critical environmental, social and governance (ESG) initiatives.

The company’s Sustainability Report details the company’s performance in four key areas – customers, growth, operations and employees. 

Duke Energy’s 2020 Climate Report discusses how the company is addressing climate change by reducing carbon emissions and making its electric grid more resilient.

“Our commitment to ESG has delivered strong results for our customers and our shareholders – and we’re focused on maintaining this level of performance and transparency as we work to achieve net-zero carbon emissions by 2050,” says Lynn Good, chair, president and CEO of Duke Energy. 

“These two reports showcase the significant progress we’ve made in these areas, and our plan to help address the challenges from climate change,” adds Good.

The company’s Sustainability Report highlights its progress toward its sustainability goals:  

  • Energy efficiency: Duke Energy’s goals to reduce customer energy consumption and peak demand were both exceeded in 2019. The company has set even more aggressive energy efficiency goals for 2020.
  • Investing in renewable energy: Duke Energy plans to double its renewable energy portfolio within five years. In 2019, the company owned, operated and contracted over 8,000 MW of capacity. In the new report, Duke Energy is establishing a goal of 16,000 MW by the end of 2025.
  • Providing value to customers: The company continues to provide electricity at prices below the national average in all six states it serves while maintaining high reliability.

Duke Energy’s 2020 Climate Report underscores the company’s progress toward its new climate goals. Duke Energy reduced carbon emissions from electricity generation by an additional 8% in 2019 from 2005 levels, bringing total reductions to 39%.

The analysis in the report confirms that the company is on track to achieve its 2030 goal of reducing carbon emissions from electricity generation by at least 50% from 2005 levels.

The report goes on to provide insights into the complexities and opportunities ahead in the path toward net-zero carbon emissions and provides an enterprise-level scenario analysis with an illustrative path to net-zero carbon emissions by 2050.

The net-zero scenario analysis underscores the fact that Duke Energy will be significantly increasing its use of renewable energy, and highlights the critical role that natural gas, nuclear and energy storage must play in decarbonization and in balancing the renewable additions. Additionally, the report discusses Duke Energy’s continued commitment to energy efficiency and demand-side management, as it will play an important role. 

The 2020 Climate Report highlights the necessity of advancing the development and commercial viability of new zero-emitting generation technologies for Duke Energy to achieve its net-zero goal. This analysis places further emphasis on timely R&D efforts.

Solar, wind and hydro resilient during Covid-19 crisis

A study by the International Energy Agency into the chilling effect of the Covid-19 pandemic on energy demand states renewables will be ‘the only energy source likely to experience demand growth for the rest of 2020’. The slower the economic recovery, the more the fossil fuel industry will suffer.

Renewable energy will always fall short against fossil fuels and nuclear because solar and wind output cannot easily be configured to meet demand. That is an argument frequently levelled at the clean energy industry despite the advances being made in energy storage.

However, the report published by the International Energy Agency (IEA) today, examining the implications of the Covid-19 pandemic on global energy systems, points out the decoupled nature of renewables generation and demand has proven a strength during the crisis.

The Global Energy Review 2020 also undercuts the frequent complaint heard from the renewables lobby that clean energy does not enjoy sufficient policy support. The report’s authors point out the priority dispatch afforded renewables is a key reason solar, hydro and wind power have proven resilient in the face of an unprecedented slump in energy demand.

The fall

With the IEA predicting global energy demand will fall 6% this year, electricity generation sources more closely pegged to consumption patterns are set for a crunch time, according to the report’s authors, with solar, hydro and wind expected to be the only winners.

Based on a gradual, ‘U-shaped’ economic recovery from the pandemic, the IEA estimates coal-fired electricity generation will fall more than 10% this year, as part of an 8% demand slump. Gas consumption will see its biggest ever fall – 5% – despite low prices seeing it retreat only 2% in the first quarter, and oil demand will fall 9% this year because of the slump in mobility and aviation. With nuclear-powered electricity set to fall 3% from last year’s record level and biofuels hit by mobility restrictions, renewables are expected to be the only electricity source to grow during 2020.

The IEA reported the share of solar and wind power in the generation mix rose to 9% in the first quarter, compared with 8% in the same period of last year. That rise came on the back of more than 100 GW of solar generation capacity which was added in 2019 along with around 60 GW of wind facilities. Priority dispatch – in part driven by the low operating costs of renewables plants, as the IEA acknowledged – has been key to that Covid-19 resilience. Lump in hydropower, and renewables accounted for almost 28% of electricity generation in the first three months of the year.

Economic recovery

The IEA noted the material uncertainty about hydropower output for 2020, given its dependence on rainfall and temperature levels, but said: “Solar PV is set to increase the fastest of all renewable energy sources in 2020.” The report did, however, mention the material uncertainty affecting the small scale solar sector, with installations having “stopped or dramatically slowed” as lockdown restrictions were brought in. Economic uncertainty is expected to derail, or at least delay, the plans of many householders to install rooftop solar.

In a note which will no doubt be seized upon by fossil fuel lobby groups and their political allies, the IEA report noted a faster, V-shaped economic recovery from the pandemic would lessen the blow to oil, coal and gas demand whereas an even more drawn-out recession would further accelerate the ascension of renewables. The fact that hinges solely on the amount of damage to fossil fuel demand, however, was reflected by the statement: “Renewables are the only energy source likely to experience demand growth across the remainder of 2020 regardless of the length of lockdown or strength of recovery.”

Carbon emissions

The fall in energy demand prompted the IEA to predict the world would see the largest fall in CO2 emissions on record, almost 8% – nearly 2.6 gigatons. However the international body warned the rebound in emissions could be even larger – as was the case after the 2008 global financial crisis – unless economic stimulus packages being introduced by governments pegged the recovery to low-carbon conditions. In that respect, the IEA noted the recovery package pledged by the Chinese government could have existential effects on the fate of the coal industry.

Little mention was made of energy storage in the report and, on the subject of e-mobility, the IEA reported that although electric vehicle (EV) sales have held up in Europe so far during the crisis, they have fallen even further than the overall rate of car purchases in China, the world’s largest EV market.

Regardless of the sector-by-sector breakdown, though, there is little denying the contention of IEA executive director Fatih Birol that “the energy industry that emerges from this crisis will be significantly different from the one that came before.”

This is your SolarWakeup for April 30th, 2020

Get The House In Order. As we near the 8 week mark of the shelter in place orders and a new normal, it is understandable for people to expect others to adapt like everyone has. In this case I am talking about building departments and utilities, particularly PG&E. The solar industry has been patient and working with all involved to make solar installations safe. Meanwhile, PG&E was slammed in court yesterday regarding their operations around tree trimming and wire safety. The future of PG&E should be like a highway operator. The roads need to be safe and run smoothly with local exits and high speed left lanes. When it comes to toll operations, the company needs to prioritize the speed of access to the generators that match the goals set forth by the State. The State should incentivize the company to do this well and everyone wins.

Safe Solar Sales And Installs. Being allowed to get back to work is phase I of the return that centers around building out the backlog. Phase II is the pivot many are figuring out right now. One of those things is how to generate more leads like building out digital content and driving folks to your lead generation forms. Managing this lead flow all the way through project installation without ever seeing the customer means a change to your installation company’s operating system. Next week I am hosting a live webinar with Open Solar’s Andrew Birch to ask him about his experience. In 2008, in an SPI beer garden Birchy and Danny Kennedy showed me this crazy idea on the first Apple iPad where you could type your address on a map and they would send back a layout. That was v1 of digital solar sales. You can register for the webinar here, it is limited to 100 people.

Time Of Opportunity. Buying solar assets is an art that matches sellers somewhere between desperation and greed and buyers with cash burning a hole in their pockets feeling they would miss out on yet another deal. Someone once told me (okay, it was more than once) that developers always hold assets beyond peak value and now buyers are pouncing on opportunities across the market.

It’s Valuable, Not Cheap. Headlines are making the circuit today with the cheapest solar in history. Like most reviews of solar policy across the world, solar is routinely undervalued and underpriced. That’s why many storage developers are getting away from contracted cash flows and working more like generation IPPs.

The RTOs. New Jersey had threatened earlier and now Maryland is saying they may leave PJM over the MOPR overstep by FERC. The FERC chair is urging patience and caution but maybe he should take these threats more seriously. Showdown to continue…

Opinion

Best, Yann

Mini perovskite module with 18.13% efficiency

Scientists from Singapore have developed semi-transparent perovskite solar cells that can be easily integrated into a range of urban contexts, including building facades, gates and windows. The 21cm2 mini panels are made of perovskite solar cells based on methylammonium lead iodine (MAPbI3), with an efficiency of 20.28% for 0.16 cm2.

Scientists from Nanyang Technological University, Singapore (NTU Singapore), have developed mini solar modules based on perovskites with an efficiency of 18.13%.

The 21 cm2 mini panels are made of perovskite solar cells, based on methylammonium lead iodine (MAPbI3) with an efficiency of 20.28% for 0.16 cm2. “To the best of our knowledge, the PCE value of 18.13% for PSMs is among the highest ever reported for perovskite-based devices above 10 cm2 fabricated with any deposition technique,” the researchers said.

Perovskite deposition

The cells with “n-i-p” layout were manufactured through a deposition process based on thermal co-evaporation. The researchers said their approach coupled active layer engineering and effective surface treatment, which they claim has resulted in increased charge extraction and optical light-dispersion minimization.

“Thermal evaporation is a  well-established vacuum-based coating technique that allows the sequential deposition of materials to form a multilayer architecture. It is widely adopted in the semiconductor industry to commercially produce electronics components like OLED and displays in TV and cellphones,” Annalisa Bruno, the group’s main researcher, told pv magazine.

The scientists claim that the cells showed zero losses in open-circuit voltage and short-circuit current when the active areas were scaled to 4 cm2. The perovskite cells are also said to offer stability of around 90% under 1 sun continuous illumination for over 100 h, provided by a global standard spectrum (AM1.5g) solar simulator.

The research group claims that this cell architecture could also be applied to produce a set of colored, semi-transparent perovskite solar cells and mini modules, with a respective power conversion efficiency of 16.8% and 11.2% achieved from an active area of 0.16 and 16 cm2.

Shelf stability

The unencapsulated 21 cm2 mini panels provide remarkable shelf stability, by retaining more than 95% of the initial efficiency when stored in controlled environments, with 35% humidity over periods of 60 days, the researchers stated.

The team has already demonstrated colored perovskite solar cells for BIPV applications. “The approach of tuning the transparent electrode thickness appears to be the simplest and most effective way to tune color without introducing additional layers and/or fabrication processes,” the team explained.

“The aesthetically appealing coloured semitransparent perovskite solar cells can be easily integrated in a variety of urban contexts such as building facades, gates and windows to maximize the light harvesting while improving buildings and city landscapes,” research co-author  Subodh Mhaisalkar told pv magazine.

The team describes the mini modules in Highly Efficient Thermally Co-evaporated Perovskite Solar Cells and Mini-modules, which was recently published in Joule and on the ScienceDirect website.

Despite solar woes, Tesla recorded its first profitable Q1

Tesla finished the first quarter of 2020 with a positive GAAP net income, driven by the profitability of the Model Y. However, the story was not so bright for solar, storage or corporate governance.

From pv magazine USA

For the first time in its history, U.S. electric car maker Tesla reported a positive GAAP net income in the first quarter, driven by the profitability of the new Model Y.

Tesla’s solar and storage ventures were less successful, however. And, some big boardroom news came out just before the release of its earnings report.

The company installed 35 MW of solar in the first quarter, down 35% from the 54 MW installed in the fourth quarter of 2019, and down 26% from 47 MW in the first three months of last year.

While the company has noted that it has reached the production benchmark of 1,000 solar roofs a week, launch inefficiencies with the newest offering were blamed for its lower-than-expected deployment and profits.

As for energy storage, Tesla installed 260 MWh in the first quarter, down more than 50% from 530 MWh in the fourth quarter of 2019. The company did sell its 100,000th Powerwall in the first quarter and claimed that more than 40% of solar customers have opted to install at least one Powerwall.

Vehicle production and deliveries were both down in comparison to the final three months of 2019, with the company producing just under 103,000 vehicles and delivering 88,500. On the year, vehicle production rose 33% and deliveries jumped by 40%.

The first quarter is traditionally slow for the company and turning a profit in the first three months of the year was a point of celebration. Year over year, Tesla experienced growth in vehicle deliveries, vehicle production and energy storage deployment, but solar deployment was down 26% from the first quarter of 2019.

Elephant in the room

As for the elephant in the room, the Covid-19 crisis reached its breaking point late enough into the first quarter that the full impact of the pandemic will not be reflected until the results for the next quarter. But the shutdown of Model Y production at Tesla’s facility in Fremont, California, has not dampened Musk’s ambitions for the car. He said he remains confident that it will become the company’s best-selling product ever. He made that claim just moments before remembering to read the disclaimer about forward-looking statements.

Musk vs. governance

Tesla filed an amendment to its 10K this week, and in an unprecedented move, it announced that directors and officers insurance waw too expensive, and that CEO Elon Musk would provide the coverage, for at least the next year.

Per the filing:

“Tesla determined not to renew its directors and officers liability insurance policy for the 2019-2020 year due to disproportionately high premiums quoted by insurance companies. Instead, Elon Musk agreed with Tesla to personally provide coverage substantially equivalent to such a policy for a one-year period, and the other members of the Board are third-party beneficiaries thereof. The Board concluded that because such an arrangement is governed by a binding agreement with Tesla as to which Mr. Musk does not have unilateral discretion to perform, and is intended to replace an ordinary course insurance policy, it would not impair the independent judgement of the other members of the board.”

Cost-effectiveness of PV module cooling techniques

Researchers in Malaysia have proposed a new method to determine the best way to design PV cooling systems. They will rank cooling technologies by manufacturing costs and expected panel output.

Researchers at the Multimedia University in Malaysia have formulated a new way to rank PV module cooling techniques, based on manufacturing costs and expected panel output.

The ranking also factors in panel efficiency gains from the addition of cooling systems and the wattage cost of PV electricity, research coordinator Sakhr Sultan told pv magazine. Sultan said the manufacturing cost of cooling techniques – compared to output power – has attracted little attention to date.

In A new production cost effectiveness factor for assessing photovoltaic module cooling techniques – a study that was recently published in the International Journal of Energy Research – the factor is a ratio that determines whether a proposed cooling system is cost-effective or whether it is rated neutral.

“This means that low-cost cooling techniques may also be considered feasible solutions,” Sultan said. “This occurs when the output power of a PV system with a cooler is equal to the maximum output power of a PV system under PV’s standard testing conditions and the manufacturing cost of the cooling technique is zero.”

Solar radiation, ambient temperature and air mass must also be considered to apply the factor proposed by the researchers to evaluate cost-effectiveness when comparing the performance of PV systems, both with and without cooling technologies. Standard test conditions dictate solar radiation of 1,000 W/m², cell temperature of 25 C and air mass of 1.5 spectra.

In another recent study, the same research group provided an overview of performance assessments and comparisons among different ways to keep solar panels cool when they are in operation.

Fifth 900 MW phase of 5 GW solar park moves forward in Dubai

The $570 million fifth phase of the project will sell power at $0.016953/kWh under a 25-year power purchase agreement. It is scheduled to go online in the second quarter of 2021.

The Dubai Water and Electricity Authority (DEWA) has signed a 25-year power purchase agreement with Saudi Arabia’s ACWA Power for the fifth phase of the massive Mohammed bin Rashid Al Maktoum Solar Park.

ACWA Power said that the 900 MW project will use bifacial solar panels and will require a total investment of approximately $570 million. It won a tender for the massive PV project in November with a bid of $0.016953/kWh.

DEWA initially received proposals from 64 bidders. The huge solar project is expected to begin commercial operations in the second quarter of 2021.

ACWA Power will own 40% of the company operating the project, while DEWA will hold the remaining 60%. DEWA said in November that the fifth phase of the solar park will be commissioned in stages from the second quarter of 2021.

Massive project

About 1,013 MW of the 5 GW solar park is currently operational. The first 13 MW phase was followed by a 200 MW second phase and a third phase with 800 MW of solar capacity. U.S. thin-film module maker First Solar developed the first phase in late 2013, while the second phase of the massive PV plant was constructed by ACWA Power and Spanish engineering services provider TSK.

French energy giant EDF began work on the third 800 MW phase in 2017. This section of the project will sell power to DEWA at a rate of $0.029/kWh.

The fourth phase, which was originally meant to feature 700 MW of concentrated solar power capacity (CSP), but was later expanded with 250 MW of PV capacity, is being developed by ACWA Power. The PV portion of the fourth phase will sell electricity for $0.024/kWh. For the CSP section, ACWA and DEWA have agreed on a rate of $0.073/kWh.

The entire Mohammed bin Rashid Al Maktoum Solar Park, which is also set to include large-scale storage capacity and hydrogen facilities, is scheduled for completion by 2030.

Solar can drive down levelized cost of desalinated water

A study from Finland’s Lappeenranta University of Technology states decarbonization of desalination could help achieve a levelized cost of water of €0.32-1.66 per cubic meter. Solar and storage are expected to play a decisive role.

The global average levelized cost of drinking water (LCOW) from desalination plants could decline from around €2.40/m3 in 2015 to €1.05 by 2050 if solar, storage systems and other renewable energies are used to decarbonize the sector.

That is one of the key findings of the Strengthening the global water supply through a decarbonized global desalination sector and improved irrigation systems, study by the Lappeenranta University of Technology (LUT) in Finland. The report, written by professor of solar economy Christian Breyer and his team, has been published in Energy and on the ScienceDirect website.

According to the paper, the cost of desalinated water in most regions could range from €0.32/m3 to €1.66 by 2050, including delivery expense. The researchers specified some regions of China, India, Australia and the U.S. could be among the areas where drinking water costs less than a euro.

Solar and storage, as well as wind power, gas and thermal energy will power desalination operations, according to the LUT study. “The energy demand to transport the desalinated water from the coastline … is also accounted for in each time step,” the authors of the study stated.

The report’s authors noted the energy transition is set to see the levelized cost of energy (LCOE) fall from around €180/MWh five years ago to around €50 by mid century. “In 2050, solar PV plants and battery storage [will] account for the largest share of the LCOE,” stated the report.

In a previous study, Breyer and his team described how a renewables-based global energy system would be cleaner, cheaper and better equipped to fight climate change and would also reduce water consumption from conventional power generation by more than 95%. That report estimated solar generation requires just 2-15% of the water used by coal and nuclear power plants for each megawatt-hour produced.

Covid-19 weekly briefing: Merchant solar developers could seek shelter in return to subsidies and PPAs are being revisited, but at least the Irish are coping with lockdown measures

The unfolding effects of the Covid-19 crisis, and fears of a possible second wave, have split analysts trying to guess how the unsubsidized renewables market will emerge as slumping demand continued to distort power markets. pv magazine rounds up the week’s coronavirus developments.

Staff from London-based law firm Fieldfisher, in an article for pv magazine, today said negotiations between corporate clean energy buyers and renewables project owners have resumed over power purchase agreements (PPAs), particularly in the Netherlands, Spain, Portugal and the U.K. Now the dust is starting to settle after the initial Covid-19-related chill on PPA contracts, Fieldfisher staff said deals related to longer-term energy projects are unlikely to be notably affected but negotiations are taking place regarding more imminent power projects, as corporate energy off-takers are not keen to honor commitments to buy power they currently do not need. The situation could render energy storage more attractive if battery prices come down and energy regulators properly recognize the services such facilities can provide, according to Fieldfisher, and corporates previously wary of signing power deals with aggregators of multiple small renewables generators may be more open to the idea as it offers an opportunity to spread risk.

U.S.-owned, London-based analyst Wood Mackenzie has speculated solar developers in Europe previously prepared to operate unsubsidized power plants may seek the shelter of a return to subsidies amid fears future Covid-19 waves could further damage revenues. The knock-on effect could be less generation capacity being allocated from auctions as limited subsidy pots have to work harder. Negative energy prices in Germany and Italy have put further pressure on gas generation now that much of Europe’s coal fleet has already been decommissioned. Across the pond, long-standing commercial and industrial clean energy off-takers are expected to continue investment in the U.S. although sectors which are suffering, such as oil and gas firms, can be expected to reduce renewables spending to shore up their core balance sheets. In Asia, WoodMac said any retreat by global investors would leave space for raised Chinese infrastructure spending. In the Caribbean and Central America, low oil prices could delay the transition to renewables and natural gas and in Mexico the analyst said the decision of electric utility CFE not to apply its high consumption domestic rate for power during the lockdown removed a big incentive to install rooftop solar. That move is likely to further hit the rooftop market at a time when the peso-dollar exchange rate is already driving up system prices.

Bill payment holidays

Ukrainian legal firm Hillmont Partners has assessed the impacts of the Covid-19 crisis on renewable energy producers in its back yard and around the world for pv magazine. In Ukraine, clean energy producers have reportedly ignored dispatch orders issued by electricity transmission system operator NPC Ukrenergo as it tries to balance the system during steep falls in demand during the current crisis. Government measures enabling householders to delay the payment of their electric bills have hit the liquidity of the guaranteed buyer of power generated by subsidized clean energy facilities, with the amount owed to renewables generators reaching UAH4.7 billion ($173 million) this month. That pattern has been repeated outside Ukraine too, with Hillmont predicting cashflows for paying commitments such as renewables payments could dry up at electricity distribution system operators within 2-3 months. The legal firm called for policymakers to emulate their peers in nations including Poland and India by extending clean energy project completion deadlines linked to the provision of subsidies.

A call has been made to extend solar project deadlines connected to the Investment Tax Credit (ITC) available in the U.S. Although solar projects are eligible for Covid-19 federal assistance, ITC deadlines could negate the beneficial effects. The ITC is due to fall from 26% this year to 22% in 2021. Elsewhere, the California Energy Commission confirmed solar and energy storage installers are classed as essential critical infrastructure workers, as far as coronavirus-related stay-at-home orders are concerned.

Power demand

English analyst Cornwall Insight yesterday shone light on how the Irish are coping with the Covid-19 lockdown put in place until at least Tuesday – they’re having a lie-in. With average daily electricity demand down 20% – 23.4 GWh – from the first week of March to last week, demand is down 254 MW across the day, compared with the same period of last year, and peak power demand is down 4%, or 240 MW, by the same measure. Against that background the morning peak demand period, which has been most notably reduced, has also been pushed back two hours, with people either working from home or unemployed.

Meanwhile, Irish transmission system operator Eirgrid on Monday reminded renewable energy project developers they have until tomorrow to pre-qualify for the first round of the Renewable Electricity Support Scheme. The deadline for applications for the opening round of the nation’s first clean energy tender program was extended from April 2 until tomorrow because of the Covid-19 pandemic.

Technical advisory company PI Berlin is offering to conduct audits of Chinese factories which are producing personal protective equipment (PPE) to make sure it complies with EU regulations. The German company, whose Shanghai staff will carry out the factory visits, said it would offer the service for less than market rate and would donate the proceeds to organizations distributing medical supplies.

Impact

Chinese PV project developer Comtec Solar, which turned its back on manufacturing last year to focus on its downstream business, has said it expects the public health crisis to affect operations in the first half of this year. Comtec, which is prepared to listen for offers for its solar fabs in Shanghai and Haian, stated in the annual report for 2019: “The group expects its project developments and construction to potentially be impacted and this may, in turn, affect the group’s business performance in the first half of 2020.”

The Polish solar manufacturing industry is reportedly considering a joint offensive to claim domestic market share for their products at the expense of Chinese, Vietnamese and Italian imports disrupted by the coronavirus pandemic.

The Turkish government has postponed a planned 1 GW national solar tender for a second time, this time citing the Covid-19 pandemic. The 100-project, 39-province Renewable Energy Resources Area Project (Yeka) tender has been postponed until next year. It was originally envisaged as a three-project exercise in January 2019.

Warning

Global business interests lobby group the World Economic Forum has said the Covid-19 pandemic which has cost so many lives is merely a taster of what lies in store for the planet if climate change is not addressed. The corporate lobby group – which hosts the annual Davos conference in Switzerland – added the public health crisis offers the opportunity to rebuild a more sustainable, resilient world better placed to reduce the emissions which are fueling climate change. That message was echoed on Monday by more than 60 blue chip German businesses who have demanded post-Covid-19 stimulus packages should be linked to reducing emissions. The German government has thus far resisted calls to lock climate change conditions into the support policies it is planning to deal with the economic fallout of the pandemic.

New South Wales-based renewables investment fund Solar Bay has offered a financial lifeline to businesses in the Asia-Pacific region which own rooftop solar assets. The fund has an AU$350 million (US$223 million) war chest to purchase commercial and industrial systems which it will use to supply energy back to the original owner under long-term power supply contracts. Solar Bay said the energy costs for businesses could still be 20-40% lower than wholesale prices and the sale of rooftop systems could give businesses much-needed cash as the financial fallout from the coronavirus crisis sets in. Solar Bay expects to spend almost a third of its AU$350 million to purchase PV rooftops within six months.

A silver lining

Chinese energy storage manufacturer BYD says its engineers and those at German electronics company Kostal have overcome Covid-19 work disruption to make BYD’s Battery Box Premium product compatible with the latter’s Plenticore and Plenticore Plus products. BYD said “very well stocked warehouses around the world” will compensate for coronavirus-related shipment restrictions as demand for its products is expected to treble this quarter, compared with the same period of last year.

Silver prices will only fall 3% this year despite the impact the Covid-19 crisis will have on demand, according to the U.S.-based Silver Institute. Silver demand is forecast to slide 3% in the global PV industry, from 98.7 million ounces in 2019 to 96.1 million ounces this year.

Uptick

The boss of Utah-based energy storage system manufacturer Humless has insisted his business has seen a rise in demand since the onset of the Covid-19 pandemic in the U.S. Chief executive Glenn Jakins cast doubt on the findings of a survey undertaken by industry body the U.S. Energy Storage Association (ESA) this month which stated a quarter of storage companies expected to have to lay-off employees because of the public health crisis. Some 63% of the 101 respondents to the ESA survey said they expected revenue to fall this quarter, with 33% expecting falls of 20% or more and storage system manufacturers more pessimistic than developers and installers, according to the ESA. Customer delays and cancellations, equipment shortages and permitting hold-ups were cited as the chief problems companies expected to have to overcome. The ESA has appealed to Congress and the White House for support and claimed even companies with no immediate concerns about employment might lay-off workers if the situation does not improve rapidly after June.

India’s Ministry of New and Renewable Energy on Thursday announced this year’s Global Renewable Energy Investors’ Meet and expo event will be held digitally, because of the Covid-19 pandemic. The ministry is now seeking an IT partner to host the event, which is scheduled for October 15-17.

Arkansas Public Service Commission Approves Searcy Solar Project

The Arkansas Public Service Commission has approved a new utility-scale solar project that will provide Entergy Arkansas customers with 100 MW of solar power and 10 MW of battery storage.

The Searcy Solar project in White County will be the largest utility-owned solar project in the state and the first to feature battery storage.

When completed in 2021, it will be the third project generating solar energy for Entergy Arkansas’ customers, bringing the total of solar energy to 281 MW covering more than 2,000 acres. The Stuttgart Solar Energy Center has been producing 81 MW of solar energy since 2018, and Chicot Solar, under construction near Lake Village, will provide 100 MW of solar power when it comes online later this year.

“Entergy Arkansas is proud to be expanding solar power in our state, and we are committed to meeting our customers’ energy needs reliably, affordably and safely as we have done for over 100 years,” says Laura Landreaux, president and CEO of Entergy Arkansas. 

“Large-scale solar facilities provide the most cost-effective solar power for all customers, keeping rates low while delivering the best value for renewables in Arkansas,” she adds.

The Searcy Solar project will be built on approximately 800 acres east of Eastline Road (US 67, Exit 44) in Searcy and will include a 10 MW array of lithium-ion batteries capable of storing up to 30 MW hours of electricity, which is expected to be charged and discharged daily to maximize the value of the solar energy for the benefit of customers.

The Searcy Solar facility will bring 200 temporary construction jobs and two or three permanent jobs, along with periodic maintenance workers. It also will provide about $700,000 in annual property taxes as well as environmental benefits through emissions-free energy.

Huawei, Sungrow and SMA dominate global inverter market

Analysis from Wood Mackenzie shows global inverter demand grew 18% last year. The ten largest inverter suppliers accounted for 76% of the global trade.

The global solar inverter market grew 18% in 2019, according to new data from U.S.-owned analyst Wood Mackenzie.

The WoodMac analysts said two trends were critical: U.S. demand ahead of the reduction in the solar Investment Tax Credit at the end of last year and a rise in demand for the retrofitting of products in operational solar plants.

Asia-Pacific is still the center of global demand although the market declined slightly last year, according to WoodMac.

Chinese manufacturer Huawei led the field with the top three manufacturers unchanged for five years. Chinese rival Sungrow had the second biggest slice of the market again, ahead of German outfit SMA. U.S. company Power Electronics claimed fourth position thanks to dominance in its domestic market, even if it lost U.S. market share to Sungrow during the year, according to the WoodMac analysts.

Italian inverter maker Fimer enjoyed the biggest growth, climbing to fifth after it took over the solar inverter business of Swiss company ABB.

The big five surrendered only 1% of their stranglehold on the global market to claim 56% of business. WoodMac said the 10 biggest inverter makers accounted for 76% of global trade.
