For nearly two days during Winter Storm Fern, petroleum surpassed natural gas as New England's primary source of electricity—a massive spike for a fuel that typically accounts for less than 1% of total US power.
For context: About 41% of the region's natural gas capacity is "dual-fuel," meaning plants can switch to burning distillate fuel oil when natural gas supplies are constrained or diverted for home heating.
