The United States’ electrical grid is old and vulnerable – power outages are on the rise. Each new natural disaster or powerful storm exposes that vulnerability. For New York it was Hurricane Sandy. Three years ago the storm blacked out many coastal areas for weeks. Now the state is looking for strategies to re-make and strengthen its electrical system.
At Frank’s Pizza, on Main Street in Port Washington, Long Island, Linda Colombo does not stop working for an interview. While she talks with me, she slices pizza, pulls food in and out of ovens, and folds her famous pepperoni rolls.
Take away the electric lights, and add a headlamp for Linda and a crowd of hungry Long Islanders, and you have the picture of what the pizza place looked like the day after New York was hit by Superstorm Sandy.
“The first day I had my miner’s hat on, because I didn’t have a generator yet,” Colombo said. “The first night, it was like, crazy.”
Frank’s only lost power for a few days, but other Port Washington residents were out for much longer. On Long Island alone, of the 1.1 million customers served by the Long Island Power Authority – or LIPA – 90 percent lost power during Sandy. In the aftermath, New York’s Governor Andrew Cuomo came down on the utility – hard.
“LIPA is broken,” he said in 2013. It is the status quo and it’s failed.”
The state brought in a private utility company to take over most of LIPA’s operations. To upgrade service, that company blanketed Long Island with replacement utility poles, hundreds of which were in the Port Washington area.
“This charming seaside community, all of the sudden with no notice we woke up to these 80-foot poles strung with wires,” said Mindy Germain, director of Residents for a More Beautiful Port Washington. “You just felt like you were in a prison.”
The town didn’t like that solution. So now, along with 83 other communities, they’re competing in a statewide contest to develop something different – a microgrid. The contest is part of a multi-billion dollar project in New York designed to strengthen critical infrastructure.
A microgrid is a standalone electrical system that can operate independently of the larger grid during a storm or power outage.
New York wants communities to develop them for critical services like hospitals and water treatment centers – and to keep residents’ lights on.
“What we like about the competition,” Germain said, “is it’s an opportunity for us to island off critical resources. But it’s also an opportunity to look at renewables. And that’s what we really are fascinated by.”
And she is not alone. Up until recently, interest in microgrids has mainly focused on resiliency – keeping power on when the main grid fails.
Francis O’Sullivan, director of research for MIT’s Energy Initiative, says that’s a natural fit for microgrids.
“But increasingly,” he said, “with the development of lower cost photovoltaics that can be deployed at the rooftop or at the community level, coupled to the availability of lower cost storage technologies, there’s this broader suite of applications for microgrids opening up.”
It’s a suite of applications that will substitute diesel generators – currently the option of choice for powering many microgrids – with more green solutions.
O’Sullivan says we don’t yet know what that might look like from place to place. But the number of examples is growing.
Connecticut’s Wesleyan University has a microgrid, Alaska runs over 200, some as old as 50 years. Utilities in California are looking to microgrids as well, as a way to meet the state’s requirement that 50% of energy supplies should come from renewable sources, by 2020.
“Only through that kind of learning by doing will we actually begin to understand what the practical benefits of microgrids will ultimately look like,” O’Sullivan said.
In Port Washington, Germain says they’re looking at options like using the high school’s roof for solar, and looping the library and a senior housing center into the grid.
A plan in the Bronx aims to protect New York City’s largest food distribution center. Towns elsewhere in the state want to incorporate tidal power, or use local dams to provide hydroelectric energy. Ultimately, fewer than 10 of the 83 projects under development will receive state grants for construction.
In the meantime, Linda Colombo says she and her neighbors aren’t waiting around. They’ve taken resiliency into their own hands.
“Since Sandy, I bought by generator,” she said. “I never had to use it. We’re waiting for the next one, you know?”
