BTW solar and wind energy production is pretty predictable in certain parts of the country......ie. solar in S. CA and wind in West TX. Yeah.. the sun shines 12 hours a day (if that) and the wind blows on average approx 350 days a year. But what do we do when the sun doesn't shine (especially at night), or the wind fails to blow? We do the same thing we do when hydroelectric doesn't flow. Other sources step up and carry the load. System operators curtailed power to interruptible customers to shave 1,100 megawatts of demand within 10 minutes, ERCOT said. Interruptible customers are generally large industrial customers who are paid to reduce power use when emergencies occur. No other customers lost power during the emergency, ERCOT said. Interruptible customers were restored in about 90 minutes and the emergency was over in three hours. ERCOT said the grid's frequency dropped suddenly when wind production fell from more than 1,700 megawatts, before the event, to 300 MW when the emergency was declared. Yes. We're still in the learning curve but we are getting better at it. Too negative.
