Are Renewable Generators Price Responsive?

We examine the responsiveness of renewable generators to short-run electricity prices. Pairing high frequency generation data for individual renewable generators in Texas with spatially-detailed meteorological data, we find that wind-powered facilities increase their output in response to high day-ahead market prices conditional on local meteorological conditions. We find solar-powered facilities, once eliminating the possibility for price-induced curtailment (observed generation being lower than potential generation), are not price responsive. Using instrumental and time-shifted variable methods to address endogeneity concerns, we find an average short-run price elasticity for wind generators to be on the order of 0.10 for wind-powered facilities. Price-responsiveness is greatest for unsubsidized wind farms and those with more market exposure, consistent with theoretical predictions. Our estimates reveal an overlooked intensive margin of operational adjustments by renewable firms. We illustrate the quantitative importance of this margin under a shorter-term scenario where demand has accelerated rapidly but generation capacity has remained relatively fixed and under a longer-term scenario with high deployment of renewable generation capacity.
