Battery Storage Playing Increasingly Important Role on California Grid

The intermittent nature of renewable energy is a well-documented thorn in the side of efforts to decarbonize the power grid, especially with more wind and solar generation coming online every year. But while those sources of clean energy are not available all the time, it’s also true that they can sometimes produce more power than transmission lines or a power grid can handle during other periods, leading to curtailments. An increasingly important tool that can lessen the impact of both problems is power storage. In today’s RBN blog, we’ll address the limitations of today’s storage options and look at how long-duration energy storage (LDES) could play a critical role in the years ahead.

Discussions about electric vehicles (EVs) often focus on the additional demands they will put on the power grid in future years, with concerns about the grid’s reliability and ability to meet peak demand often taking center stage. There’s no doubt that a widespread transition to EVs would pose real challenges, but utilities in California and elsewhere are also starting to think creatively about how to transform those challenges into an opportunity — although there are significant hurdles to clear along the way, including the needed buy-in from EV owners. In today’s RBN blog, we explain California’s so-called duck curve, show how certain EV solutions aim to address some of the power grid’s current problems, and look at some ways to get EV drivers to become active (and willing) participants in a vehicle-to-grid (V2G) initiative, which increasingly looks like an essential element in any long-term plan.
