How do renewables affect wholesale electricity prices?

The rapid rise of renewables, particularly wind and solar, has increased volatility in wholesale electricity markets. Daytime oversupply depresses prices — often into negative territory — while evening demand spikes have become sharper.

How does oversupply affect solar prices?

Daytime oversupply depresses prices — often into negative territory — while evening demand spikes have become sharper. A relatively mature market, especially in Europe, has become more competitive, said one European asset owner, raising pressure on solar owners and operators to deliver more predictable returns.
