If You Had A Microgrid, You Wouldn't Be Waiting For The Power Company

Why spend billions on restringing, burying, or waterproofing power lines? True post-storm resilience lies in onsite renewable energy.

Last week, 8.5 million people in the Northeast lost power, most for days, due to Hurricane Sandy. A week later, with temperatures dropping, nearly 2 million people are still in the dark. Estimates of the cost in lost business alone start at $20 billion—to say nothing of the elderly and vulnerable trapped in public high-rises without elevators or flushing toilets.

Despite the emerging political consensus that Sandy was the first of a trend, the discussion around our power grid has focused on restoring business as usual: stapling lines back on poles, pumping out flooded substations, putting natural gas and coal-fired power plants back in operation, and, at most, investing billions to bury power lines or waterproof the ones that are already buried. But there is another way, one that doesn’t involve rewarding the electric utilities with more money from you, the ratepayer.

Three years ago, I wrote a story for Fast Company, "Why The Microgrid Could Be The Answer To Our Energy Crisis," which lays out another way: Replace vast, centralized power plants with local clean and renewable energy, whether methane, rooftop solar, or nearby wind, combined with onsite storage from a battery or fuel cell.

'Distributed generation’ means a redundant, resilient, secure infrastructure—that’s why military bases and hospitals have their own power plants. Micropower can be more reliable, given that 98% of all blackouts originate in the grid. And it creates thousands of local jobs near population centers in design, installation, and maintenance.

Earlier this year, the U.S. military, which knows a little something about risk assessment, announced plans to open up 16 million acres of its own land to onshore and offshore renewable energy installations to make its bases more self-sufficient in case of power outages. The Marine Corps Air Station in San Diego, known as the Top Gun flight school, switched on a renewable methane power plant in June that provides half of its energy and is on its way to being fully self-sufficient. James Newcomb at the Rocky Mountain Institute, which has been at the forefront of micropower research and advocacy for years, also points to UC San Diego, which was able to "island" itself from the larger power grid and keep the lights on during the major Southern California blackout in September 2011 thanks to an onsite natural-gas-powered heat and electricity plant. Denmark, which relies heavily on wind, is likewise rebuilding its entire grid on a "cellular control" model. Individual "cells" will be able to operate independently if the grid is knocked out elsewhere.

Battery technology is getting better. So is "smart grid" software to manage variable and multiple supplies of power. Rather than rely on dirty, expensive backup diesel generators, shouldn’t New York City’s hospitals be investing in fuel cells, solar, and co-generation? As FEMA pays out to the hundreds of thousands of homes and small businesses affected by the storm, shouldn’t they include incentives for weatherproofing and solar leasing to make these communities more efficient and self-sufficient? If I had insurance money coming from a home in Brooklyn or the Jersey Shore, I might be looking upstate to , a development of newly built zero-net-energy homes in four different neighborhoods in New Paltz. Never fear an outage again when your home sips energy from the sun.

Historically, utilities have openly opposed this kind of development because their business model depends on centralized production and distribution of energy. But before we throw more good money after bad to rebuild those private companies’ assets, this is a moment of opportunity. Governor Cuomo has already threatened utilities’ rights to operate in the state if they come up short in the repair process. Why not tighten the screws to get them to invest in a real solution before this happens again?

    Hmmm... Wonder what Sandy would have done to solar rooftop panels and "nearby wind." Nothing like a turbine blade slashing through your house....

    Do more fact checking rather than relying on movies. Miramar has been a Marine Corps Air Station going on two decades now, after being reclaimed by the Marines. "Top Gun" is a Navy program and is located in Nevada or Arizona - some land-bound state.

    Sorry, I don't normally make a comment on such articles, but I'm afraid I don't understand EXACTLY how you would replace the current grid/ utility support structure with alternative energy production. Could you please produce a sequel to this piece, explaining on a technical basis just how you would be able to produce the quantity of electricity necessary to support the storm stricken areas. It should include something of the physical laws of nature with regards to solar, wind and fuel cell production against the current mode of operation, as well as an inkling of the enormous costs involved and who will bear those costs. Science please?

    If you read the original article, there are numerous citations to support the idea that up to half of American houses could be providing their own energy. A key part of this evolution has to do with retrofitting homes to consume far less electricity in the first place, a process that pays for itself at current electric rates. As does rooftop solar, which is why solar leasing operations such as Sungevity  will put panels on homes and businesses for free.
    A good resource on the topic is Rocky Mountain Institute's book Small is Profitable. http://www.rmi.org/Knowledge-C...
