Burning Through Emissions Limits -- Faux Environmentalists -- We Don't Need No Pipelines; We Don't Need No Fracking; We Don't Need No Coal -- The Road To New England -- January 6, 2018

From the EIA: northeastern winter energy alert

And then this, a re-posting. This is simply such an incredible story on so many levels, I did not want it "lost" as an update to an earlier post.

As a reader suspected -- dual-fuel units are switching to oil, burning through emissions limits A huge "thank you" to another reader for spotting this.
New Yorkers and New Englanders are cranking up their thermostats to stay warm amid an extreme cold snap, but New England's grid overseer and its generators are finding that dual fuel generators are burning through not only needed wintertime oil supplies but also emissions allowances for the rest of the year.

ISO New England spokesperson Marcia Blomberg said the regional power system is operating under normal conditions but the extreme cold weather is increasing demand for natural gas for heating, creating pipeline constraints, driving up natural gas prices and causing dual-fuel generators to switch fuels. As a consequence, oil- and coal-fired power plants are generating much more power than usual and wholesale power prices have soared, said Blomberg.

As of 10:30 a.m. on Jan. 2, 34% of New England's electricity was being supplied by oil-fired generation (which over a given year supplies less than 1% of the region's generation), followed by natural gas at 25%, nuclear at 23%, renewables at 9%, coal at 6% and hydro at 4%. Of the renewable generation, 62% of it was supplied by greenhouse gas-emitting wood-, refuse- and landfill gas-fired generation, with wind supplying 38% and solar less than 1%. According to data from SNL Energy, ISO-NE's internal hub clocked a day-ahead power price of $210/MWh at peak on Jan. 2, up from a Dec. 22 peak of just $66.25/MWh.

In neighboring New York, which also faces wintertime gas capacity constraints, grid overseer New York ISO said the state has sufficient generation capacity and reserves to meet Jan. 2's projected peak demand of 24,500 MW, with some dual fuel units switching to oil as a result of increased demand for natural gas and both higher gas and wholesale electricity prices. According to the NYISO, dual fuel resources supplied nearly 30% of the state's generation at 12:15 p.m. on Jan. 2, followed by nuclear at roughly 28%, hydro at almost 15% and natural gas at approximately 14%.

New York's Hudson Valley saw power prices skyrocket to $205.50/MWh for Jan. 2 day-ahead markets compared with just $35/MWh on Dec. 22, while New York City area day-ahead prices increased to $215.25/MWh compared with $35/MWh on Dec. 22, and Western New York day-ahead prices soared to $195/MWh from $29.75/MWh on Dec. 22.
