Before the U.S. electric grid became centralized under utilities and independent system operators, it consisted of unorganized and unconnected generators. As distributed energy resources (DERs) – such as rooftop solar, energy storage, and other generation sources beyond large power plants – find their way into (and onto) more homes and businesses, it’s clear the grid’s future has a lot in common with its roots. This time, however, an array of new technologies will help us take advantage of a more decentralized approach.
But are utilities ready to handle this change? Although some are eager to try, the answer under most current utility business models is a resounding “no.” This is because current business models promise utilities profit for putting more steel into the ground and selling as much energy as possible – the exact things DERs help avoid.
Despite all this, can we find ways for utilities and DERs to be friends? We think so. Meet the “Bring Your Own Battery” (BYOB) model. Developed by San Diego Gas & Electric (SDG&E) and collaborators at Rocky Mountain Institute’s eLab Accelerator, it capitalizes on the emerging movement of customers bringing their own batteries to the grid. What’s more, it creates a role for the utility to facilitate rather than fight the expansion of DERs.
