The pace of recovery in offtaker deals will depend on the damage to credit risk and industrial demand, requiring new contract terms and risk aggregation, experts said.
COVID-19 restrictions are impacting the short and long-term strategies of wind and solar developers.
In Europe and the US, factory closures have cut demand and short-term power prices. Supply chain disruptions have delayed project schedules and increased costs.
The pandemic is also delaying the signing of long-term power purchase agreements [PPAs] critical for most large-scale renewable energy projects.
PPA demand was surging before the crisis but business closures and the looming global downturn is impacting credit ratings and lower power demand has created uncertainty over future wholesale prices.

Amid the uncertainty, companies are postponing PPA decisions or negotiating for better terms, Paolo Ghezzo, Head of Renewables Independent Engineering at consultants RINA, told New Energy Update.
Prices must be high enough to mitigate offtaker risks and many developers may wait for prices to recover more towards pre-COVID-19 levels, Martin Scharrer, Head of Legal (Energy & Investments) at German solar and wind power investor Encavis, said.
“Projects are not as attractive as they need to be for investors, especially purely financial investors,” Scharrer said.
«It might take some time until we are back to the prices before Corona,» he warned.
Group effort
The economic fallout of COVID-19 will impact the creditworthiness of offtakers large and small. Risks will differ between country and sector.
Large corporates with strong balance sheets led early growth in renewable energy PPAs, but falling wind and solar costs have enticed a wider range of smaller, riskier offtakers into the market.
In 2018, 75 companies entered into corporate renewable energy PPAs in the US, compared with 31 in 2017, according to the Rocky Mountain Institute’s Business Renewables Center (BRC).
Increasing use of layered PPA structures in which aggregate demand from a number of offtakers could help mitigate risks, Daria Nochevnik, Principal Advisor at ECS Consulting, said.
Layered PPA structures allow smaller firms to buy power from larger projects, or spread risk across a range of different renewable assets, Nochevnik, also a communication lead at the European Federation of Energy Traders (EFET), said.
Many smaller firms seek shorter PPA contracts and this has spurred the layering of multiple contract tenors, requiring an in-depth understanding of regional power trends. The spread between PPA and wholesale prices varies between the country, depending on market-specific factors such as liquidity and national regulation.
Utility squeeze
The credit risk of utilities—major buyers of renewable energy– is also under pressure, Uday Varadarajan, Principal, Electricity at Rocky Mountain Institute (RMI), told New Energy Update.
The impact on the utility depends on the regulatory regime it operates in and its exposure to COVID-hit companies, Varadarajan said.
“If the regulatory regime includes measures to decouple the volume of consumption from total collections in a timely fashion, then the utility’s revenues are likely to be resilient to this crisis in the near term – and the counterparty risk is likely to be minimal”, he said.
If a prolonged downturn prevents customers from paying their bills, liquidity becomes an issue, Varadarajan said.
“This could be a concern for utilities like Pacific Gas & Electric (PG&E), already reeling from recent events”, he said.
PG&E filed for Chapter 11 bankruptcy protection in January 2019 after several deadly wildfires left it with billions of dollars of potential liabilities.
The Californian utility is offtaker for Berkshire Hathaway’s 550 MW Topaz PV plant in San Luis Obispo County. On April 22, Fitch Ratings affirmed senior notes for the facility at «C,» a very high level of credit risk, due to its exposure to PG&E.
«Material changes in revenue and cost profile are occurring across the power sector in the U.S. and likely to worsen in the coming weeks and months as economic activity suffers and government restrictions are maintained or expanded,» Fitch warned.
Tighter contracts
The COVID-19 crisis will bring greater scrutiny of PPA contracts, particularly in the negotiation of force majeure clauses, Scharrer said.
Companies may look to extend the period for which counterparties under force majeure are unable to terminate the contract, typically set at around 180 days, Scharrer said. Contracts may also include greater detail on risks from health and safety issues, he said.
Legal mechanisms of force majeure claims will become more prominent, while pandemic insurance options may also be introduced, Nochevnik said.
More standardization of contract terms across the industry should help mitigate risks and speed up negotiations.
Last year, EFET launched a new standard corporate power purchase agreement (CPPA) which includes terms on force majeure, change of law, and termination due to non-delivery or insolvency.
Long view
The long-term impact of COVID-19 on PPA demand and prices will depend on the length and breadth of the economic fallout.
Forward power markets in Europe indicate prices could return to levels seen before the pandemic in two to three years, Guy Brindley, Senior Analyst at industry group WindEurope, told New Energy Update.
If short-term prices remain low, some developers may still sign PPA contracts, confident they will still make long-term savings, Brindley said. Other project owners with adequate equity financing may take on merchant risk for two or three years then negotiate PPA contracts, he said.
Countries keen to stimulate new build activity could reintroduce short-term support measures such as feed-in tariffs, Scharrer said.
«It could be useful in my opinion to get the economy bouncing back quicker…plus the countries still have to fulfill their targets for renewable energies in [their] climate action plans,” he said.
Green engine
Despite the wider economic crisis, the fundamentals behind long-term PPA growth remain strong, experts said.
Falling technology costs and sustained low cost of finance have propelled renewable energy growth and these trends will continue going forward, Oyvind Breivik, head of energy communications at aluminum group Norsk Hydro, a major buyer of renewable power, said.
“Now, we are seeing even lower interest rates, and many believe this will last for a long time,” he noted.
Based on cost, PPA activity could swing in favor of solar in the coming years, Wood Mackenzie Power and Renewables said in a report published in 2019.
Falling solar costs, battery storage synergies, and favorable solar resource profiles could see U.S. corporate demand for solar soar past wind from 2021, the research group said.

Rising renewable energy targets at both a national and corporate level will continue to spur activity.
Amid the pandemic, the European Commission and European Council have reaffirmed their commitment to carbon neutrality by 2050 and pending EU-level Green Deal legislation will help support growth, Nochevnik said.
“PPAs and corporate PPAs, in particular, will remain a key instrument for facilitating the uptake of renewable energy in Europe in a cost-effective way,» she said.
