Challenges for renewable energy sellers & developers

December 14, 2021

To reduce CO2 emissions, we need to increase the production of low-carbon sources of energy. Renewable energy will play a key role in this decarbonization process. It does not come by chance that renewables are one of the fastest-growing electricity sources. However, there are significant challenges to overcome for the parties involved.

In our previous blog post, we had a close look at the challenges corporate renewable energy buyers or so-called offtakers have. This blog post will deal with the challenges renewable energy sellers or so-called producers have.


  • Decline in renewable energy subsidies
  • Creditworthiness of partners
  • Price Volatility of Electricity Markets
  • Conclusion

Get support on RE Wave with project financing and find a suitable buyer

Government programs created stability in the market and increased the confidence of investors in renewable energies. Since public subsidies are decreasing, producers or developers of renewable energy plants are looking for alternative sales channels. Another risk component for energy sellers is the high price volatility of renewables.

1. Decline in Renewable Energy Subsidies

Many governments worldwide have implemented comprehensive support programs to promote renewable energy development, such as solar and wind power. These programs created stability in the market and increased the confidence of investors in renewable energies. The subsidies also provided renewable energy sellers with secure distribution channels.

However, today governments are increasingly phasing out subsidies, replacing feed-in-tariffs by an auction system. As the diagram shows, government subsidies in wind and solar have steadily decreased since 2011.

Feed-in tariffs are one of the most essential support mechanisms. They provide renewable energy sellers with a fixed price for the power they produce. On the other hand, an auction is a competitive process for selling and purchasing power from a renewable energy plant. Power producers or project developers can submit a bid to the auction, in which they state the price for a unit of renewable electricity. The best bidders are then selected by the government according to price and other criteria.

For energy sellers, the new auction system has various drawbacks. Due to an intense competition, auctions may lead to an underbidding. This in turn may result in low energy prices and thus in decreasing revenues. There is no longer a mechanism for power sellers that secures them fixed prices for the power they generate. Decreasing green energy subsidies thus result in an increasing risk for renewable energy sellers to operate their power plants profitably and efficiently.

2. Creditworthiness of Partners

Since public green energy subsidies are decreasing, producers or developers of power plants are looking for alternative sales channels. One of the options is to find private or public renewable energy buyers, so-called offtakers. A renewable buyer is a corporate or an institution, including a utility, that wants to purchase the electricity production by the renewable energy project.

Buyers often commit to purchasing renewable energy from the project for a long period, often up to 25 years. The creditworthiness of the energy buyer is crucial. It's not only crucial to sellers of renewable energy but also to the investor and the financial institution issuing the loan for the project.

Renewable energy buyers, however, have varying degrees of creditworthiness. At the upper end of the spectrum are private corporations like Google and Amazon, which have been involved in the renewable energy market for many years. At the lower end of the spectrum are public energy buyers, especially in emerging markets and developing countries, whose bankability is medium to low.

Renewable energy sellers therefore must evaluate if they should go for a liberalized solution or try to find a partner in a regulated market. In liberalized markets, energy sellers are more likely to contract a partner, like a private corporation with high creditworthiness, than in regulated markets. In regular markets, the bankability of possible partners may be limited.

3. Price Volatility of Electricity Markets

Another risk component for energy sellers is the cost of renewable energy and the high price volatility of renewables. Price volatility describes how quickly and widely energy prices may change in the energy market, depending on changes in supply and demand. When the power supply is more significant than the demand, then prices tend to go down. When the power demand exceeds the supply, then prices usually go up.

The growing share of renewables output in the energy market portfolio results in rising price volatility. This happens since energy generation from wind turbines and solar plants highly depends on the weather conditions. This is thus unpredictable.

For example, Enverus identifies the growing influence of renewable energies as a source of higher price volatility in major US energy markets (incl. California and Texas). Also, Covid-19 is seen to have impacted the price volatility of the renewable energy market.

The EU observer sees the pandemic as a major cause for the growing price volatility of EU wind markets. Here an oversupply in electricity due to the crisis has triggered negative electricity prices. Especially markets with high wind generation output, like Germany and Denmark, are vulnerable to these hostile prices.


There surely are other issues, sellers of renewable energy assets have to deal with. This is just an outline of some major challenges. But it shows the great complexity of issues, energy sellers must master to find the right partners in the right markets.
