Solar Effects on Grid Operations.
Two graphs
First graph tracks the daily load or the number of megawatts of generation required throughout the day
Second graph tracks the price to supply electricity for this load in the first graph
It is unusual for the price to be higher for the morning peak than the evening peak, as the morning peak load is smaller than the evening peak load. This oddity has been happening more and more frequently and is especially pronounced during the recent cold periods.
Notice the shapes of the peaking curves. The morning curve is much steeper (load and prices ramp up and down over a shorter period of time) than the evening curve.
It is not unusual on cold mornings to see a quick ramp up as people awaken and reset their thermostats to warm the house, prepare breakfast and dash around getting ready to go to work and school.
The changing curve shapes are due to solar. Solar begins at sunrise which presently occurs at the point the curve starts ramping down. Around 7am.
Not only is there a steep ramp up, but with solar, there is a steep ramp down.
The steeper the curve, the more costly power becomes to satisfy load due to quickly changing dispatching of generation, which is all a function of attention to operations by the generators and the ISO-NE operation managers.
During solar impact on the grid (sunrise to sunset), operational acuteness is increased by nature of in and out solar output due to snow cover and changing cloud cover.
Solar can be described as a disturbance to traditional grid operations for the tiny capacity factor it possesses, especially during the winter.
The cost to the end users for operations are difficult to quantitate, but these pictures(graphs) tell a tale that cannot be ignored when considering the benefit-cost ratio of solar, in front of the meter as well as behind the meter.

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.
