Canadian wildfires impacting solar production, electricity demand in New England

In recent days, smoke from wildfires in Canada has traveled to New England, significantly lowering production from solar resources in the region compared to what ISO New England would expect absent the smoke.

Most solar resources in New England are connected to the distribution system and reduce demand on the regional grid when they are producing electricity. Decreased production from these resources has the effect of increasing demand on the regional grid.

ISO New England forecasters have worked to adjust consumer demand forecasts to account for these differences, as modeling software, which relies on weather forecasts, is anticipating greater production than what ISO operators are observing in real time.

The smoke has also lowered actual temperatures in New England compared to what weather models are forecasting. This leads to lower demand on the regional grid, as there is less need for things like air conditioning.

These two factors—decreased production from solar resources and decreased consumer demand due to lower temperatures—has made forecasting demand for grid electricity challenging.

It’s difficult to determine the exact impact of each of these factors, given that there are many variables affecting consumer demand for electricity at any given moment.

In forecasting real-time and future demand for electricity, ISO New England relies on historical data from similar days, adjusting for changing system conditions. Because these smoky conditions are unprecedented in the region, there is little, if any, historical information to rely on, creating further complications in generating accurate forecasts.

Despite these complications in forecasting, ISO New England continues to manage the regional grid under normal operating conditions, and does not anticipate this changing. The ISO has long-established procedures in place to maintain system reliability, should they be needed.

Increased temperature increases evaporation and cloud cover, thus reducing temperature

That is the way the earth deals with variations in solar radiation output reaching the earth, regardless of whether CO2 is present in the atmosphere or not

The temperature influence of any CO2 presence is completely overwhelmed, by about a factor of 80, by the temperature influence of the evaporation/cloud formation process

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.
