ISO-NE will require wind, intermittent hydro to bid into day-ahead energy markets

Dive Brief:

ISO New England now requires wind- and intermittent hydro resources with a capacity supply obligation to offer into the grid operator’s day-ahead energy market, the grid operator announced Tuesday.
The grid operator called it “another milestone” in its efforts to incorporate renewables into the regional marketplace. The requirement, effective June 1, comes three years after the ISO launched the Do Not Exceed (DNE) dispatch project, enabling those resources to take electronic dispatch instructions from the grid operator.
Requiring DNE resources to participate in day-ahead markets will improve resource commitments and the price convergence between the day-ahead and real-time markets, according to the ISO.

Dive Insight:

ISO-NE has been working for years to efficiently integrate renewables, and officials say the new day-ahead requirements are an important step in efficient price formation.

The grid operator said the new requirements will also help address curtailment issues which occur when the potential output of a group of resources exceeds system capacity, “leading to the resources being dispatched down or even off line in order to avoid overloading the transmission system.”

But moving forward, the ISO’s new rules mean power from resources that clear in the day-ahead energy market will not be curtailed until all the real-time-only generations are curtailed during a period with transmission constraints.

“In essence, obtaining a position in the Day-Ahead Energy Market gives the resources a better chance of being dispatched and not curtailed,” the ISO explained in a blog post.

DNE dispatchable generators must install remote terminal units which can automate the “determination and communication of real-time telemetered DNE dispatch instructions,” the ISO said on its project page.

In April, lower gas prices and reduced electricity demand led to average New England wholesale power prices that were down 40.1% in the day-ahead energy market and 38.2% in the real-time market, compared with the previous year.

If a generator files an amount of output in the day ahead market and then fails to deliver, it must pay the the cost of the real time output required to make up the difference. 

Hannah Pingree on the Maine expedited wind law

"Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine."

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?

We have the facts on our side. We have the truth on our side. All we need now is YOU.
