Solar Wants to Help Fix a Power-Grid Problem It Helped Create

By Renewable Energy World October 20, 2017

Big solar farms helped create a power-grid predicament in California. And now they’re offering to help solve it.

Solar panels have proliferated in the Golden State, flooding the grid with power supplies in the middle of the day when the sun’s out — and then quickly vanishing after sunset. This has created a sharp curve in California’s net-power demand that’s shaped like a duck. And the so-called duck curve is getting steeper every year, sending wholesale electricity prices plunging into negative territory, forcing generators offline and making it increasingly difficult to maintain the reliability of California’s transmission lines.

First Solar Inc. CEO Mark Widmar thinks he has a solution: change the way solar farms are paid. If the state’s utilities compensate them for shutting generation when the grid doesn’t need it and providing power later when it does, he said, farms could use increasingly sophisticated inverters and software controls to adjust. They’re only running full bore right now, he said, because their contracts with customers encourage them to produce as much energy as possible, he said.
