An old Cleantechnica writer (actually, our previous editor), arielschwartz/, wrote a great article this week on how a nascent smart grid helped to prevent brownouts and blackouts in New York during a record-breaking heat wave earlier this month.
Although our nation’s electricity grid has a ways to go before we can really call it a smart grid, it is great to see that initial updates and changes are already making a difference.
Here’s the part of the article about how New York City’s utility, Con Edison, used smart grid technology to help keep the grid up:
It wasn’t easy for New York City’s utility Con Edison to prevent brownouts and blackouts as the heat wave mounted. The utility went so far as to call individual customers, pleading with them to turn off nonessential appliances.
But Con Ed had a backup weapon in its fight against blackouts: an initiative that lets the utility reprogram thermostats in 20,000 homes and businesses outfitted with central air-conditioning systems. When the heat wave began, Con Ed sent radio signals to the thermostats, triggering them to cycle on and off every half hour. The initiative saved 25 megawatts of energy during peak demand last week—enough to at least partially prevent the grid from collapsing.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
