Feds measuring grid for renewables

The Federal Energy Regulatory Commission has launched a study to look at the effect of renewable energy sources on the grid. The study will assess the impact of variable and intermittent power generation like solar and wind on the grid's frequency response.

 Frequency response is the variation in the grid's operating frequency caused by the constantly shifting balance between supply and demand.

 The study will also determine if frequency response is a good measure of the impact of renewable energy on the grid, and, if it is, use the results to estimate the amount of renewable energy today's grid can handle.
