The problem is the trajectory of the transition from fossil fuel generators to solar and wind. The siting of more pipelines in the region is intensely controversial. The problem is especially acute during extended cold spells in the winter, when natural gas is used to heat homes and buildings, as well as generate electricity. But gas-burning power plants are dependent on just-in-time energy supplies from pipelines and trucks. In two decades the use of fracked gas has tripled. Inefficient, polluting fossil fuel plants and expensive-to-maintain nuclear stations have been shutting down at an increasing pace due to price pressure from relatively inexpensive natural gas. Says van Welie, “We have rapidly moved to what we're now defining as an energy limited system.”

The fuels for those plants were stockpiled on the site of large, centralized power generators.īut increasingly, our energy supplies are insecure. What concerns van Welie is energy security - reliably keeping the lights on during the transition to the new, greener grid.īack in the old, predictable days 20 years ago, climate-killing fossil fuels and carbon-free nuclear plants generated most of our electricity. “This era that we're entering into I think is going to be one of the most challenging eras of our history,' he says.

Gordon van Welie, president and CEO of ISO New England, echoes Dolan’s warning. The massive digital display is a real-time image of the region’s power grid. A view of ISO New England’s control room in Holyoke. Electricity is a commodity produced by generators, bought by utilities. How we do that is still very much an open question.'Īs grid operator, ISO New England ensures the flow of electricity runs reliably 24/7 all year, and it also maintains the online wholesale competitive marketplace. 'We have mandatory requirements to cut carbon emissions economy-wide 80% by the year 2050. 'Carbon reduction and carbon abatement overhangs everything,' he says. One thing Dolan does see clearly is the urgent need to reduce climate-disrupting emissions from the burning of fossil fuels.

It's about as cracked and cloudy as anyone else's.' 'My crystal ball doesn't see that far out. How New England's energy mix has changed since 2000 - before Pilgrim's closure (Courtesy of ISO New England)īut predicting the future mix of energy that will be used to generate our electricity, even just five years out, is difficult, even for an expert like Dolan. Renewables accounted for 6% in 2000 today it’s 9%. The closing of Pilgrim last week reduced the region’s nuclear capacity from 25% to 20%.

Meanwhile, natural gas produced 13% of our electricity now it’s 40%. They use nuclear, natural gas, hydro, wind, solar and waste to produce electricity.Īccording to the grid operator, ISO New England, 20 years ago oil generated 19% of the region’s electricity, and coal 15%. He says the system is more complex and less predictable than the grid we had just a few years ago.ĭolan's association represents 90% of electric generators in the region.

The problem: We're creating a hybrid power grid, an electric-generating network that runs on a changing combination of fuels and technologies. (Robin Lubbock/WBUR)ĭan Dolan, president of the New England Power Generators Association, says the region has a problem: “It's really hard to be half pregnant, but we're trying.” Facebook Email The closure of the Pilgrim Nuclear Power Station removes a source of carbon-free energy from the region.
