Solar to Wreck Economics of Existing Power Markets

Solar to Wreck Economics of Existing Power Markets


  1. Continued solar growth could lead to significant decreases in wholesale electricity prices during most peak hours.
  2. High solar penetrations could also impact power prices when solar does not operate, affect the frequency and severity of electricity price spikes, and impact natural gas price volatility.
  3. While lower wholesale prices could impact solar’s growth they will also hurt other energy sources, particularly coal and nuclear but also natural gas and energy efficiency.
  4. Ultimately, the price effects of solar have significant but uncertain ramifications for environmental goals, energy prices, and, ultimately, electricity market design.
