How I kept cool with NYC’s free battery program for window AC units

My family has spent four summers participating in demand response programs whereby utility companies pay customers to reduce energy use on the hottest summer days. Most summers have involved carefully precooling our New York City apartment before switching off the air conditioners and sweating it out during the designated demand response periods.

But this year, we kept our window air conditioners running throughout a heat dome event that drove daytime temperatures into the triple digits and made the nights oppressively hot. The difference was that we powered the air conditioners through two household batteries tucked away unobtrusively in the corners of our living room and bedroom.

We were among about 1,000 New York City households that took part in a free and growing program offered by the local startup Every Electric. The company’s proposition is simple: Get one or more batteries delivered to your home, plug the batteries into a standard wall electrical outlet, and then plug your window air conditioners into the batteries. Households can keep running air conditioners as usual during peak demand periods while also earning money through the local demand response program with the utility company Con Edison.
