"Market power": Capacity Markets Are Not Cost Effective
We are often told in Poland by advocates of coal that renewable energy is too expensive. They ignore the fact that onshore wind is cheaper than new coal plants right now and that PV will be cheaper during the investment life of any new coal plant planned today. The cost of renewable energy support in Poland is about 7 PLN per month on an average consumer bill of 153 PLN. Most of this has gone to electricity producers who would have generated the electricity without support (old hydro and co-firing). Had new capacity in RES been supported, the impact on consumers is normally cut in half by pressure of prices due to increased supply. Now we are told that consumers must pay to have old coal-plants standing by on the few days a year when extra power is needed. Studies in the United States have demonstrated that this is the most expensive way possible to meet peak demand. See U.S. Electric Power Research Institute (2013).* Now, however, the cost impact on consumers is being finally d...
