At minimum, grids must stop attributing fantasy reliability to solar and wind—which causes them to vastly overvalue solar and wind and make reckless plans. E.g., a typical grid will treat it as certain that at peak demand 15% of wind and 50% of solar “capacity” will work. — PolitiTweet.org

One way to stop vastly overpaying for unreliable electricity is: require all generators to meet certain reliability standards. Generators would still be able to use solar/wind *if* they took responsibility for combining it with reliables and/or storage to guarantee reliability. — PolitiTweet.org

Given the unpredictability of weather and peak demand timing even a month ahead, the effective reliable capacity of solar/wind is near 0. Even if we can expect some wind to blow somewhere in a grid area, it might be much less or more than expected, causing problems either way. — PolitiTweet.org
