ISO-New England: Electrocute Everything
Go Pats and three alternatives to the chair
In 1903, as part of his campaign against alternating current, Thomas Edison helped stage the public electrocution of Topsy the elephant at Coney Island.
Topsy was killed after her owners and handlers at Luna Park concluded she was too dangerous and too expensive to keep following a series of incidents, most notably the fatal injury of a handler in 1902. Rather than relocate her or carry out a quiet euthanasia, park management chose to turn her death into a public demonstration.
Today, five of the six New England states are pursuing a policy agenda that can fairly be summarized the same way: electrocute everything—mandating rapid decarbonization of the electricity sector while simultaneously requiring the electrification of home heating and transportation.
Luckily, there are alternatives to this Pachyderm-like pain, and they are all laid out in a handy-dandy report published by a coalition of New England public policy groups1 entitled “Alternatives to New England’s Energy Affordability Crisis,” written by the team at Always On Energy Research.
Crunching the Numbers
Our report calculated the cost and reliability implications of “electrifying everything” in New England under four scenarios.
The Renewable scenario: Detailed in this article, this scenario attempts to meet rising demand using onshore wind, offshore wind, solar, battery storage, and existing nuclear and natural gas facilities.
Nuclear scenario: This scenario uses existing gas and builds new natural gas and nuclear plants to meet demand, with nuclear accounting for 90 percent of the electricity mix by 2050.
Natural Gas scenario: This scenario adds new natural gas plants and pipelines to meet rising demand, with gas accounting for 83 percent of generation in 2050 and existing nuclear accounting for 12 percent.
Happy Medium: This scenario adds nuclear and natural gas capacity, resulting in 47 percent nuclear, 47 percent natural gas, and 3 percent hydro and “other” in 2050.
According to ISO-New England, electrifying home heating and transportation will increase the peak demand to around 57 gigawatts (GW), up from the all-time peak of 28 GW. Unlike the current peak, the forecast peak in 2050 will be in winter, not summer, due to the massive need for electricity for home heating.
Our analysis praises the wisdom of New Hampshire because it is not pursuing an electrification agenda, so we downwardly revised our system peak demand to 52.5 GW to reflect the common-sense approach to energy policy taken in the Granite State.
Meeting this 52.5 GW of future winter demand will require a massive increase in installed capacity for all scenarios. The Renewable scenario would require the most capacity, needing 225 GW to meet demand due to the intermittency of the wind and solar resources, while each of the other three scenarios could meet the projected peak with a little more than 60 GW, maintaining a healthy reserve margin.
This means the Renewable scenario required 3.75 times more capacity than the scenarios that used nuclear and natural gas to meet growing demand.
Building out this additional capacity for the region’s electrification efforts will be expensive, and the cost of electricity will rise for consumers in every scenario. However, the Renewable scenario takes the cake at an additional $815 billion, compared to $415 billion for the Nuclear scenario, $196 billion in the Happy Medium scenario, and just $107 billion in the Natural Gas scenario, as you can see in the graph below.
These costs will get passed on to ratepayers.
The Nuclear scenario would increase prices by 64.8 percent, the Natural Gas scenario by 13 percent, and the Happy Medium scenario by 26.5 percent. In comparison, prices in the Renewable scenario would increase by 126.4 percent, with massive impacts for New England families.
In 2024, residential customers paid an average yearly cost of $2,100 for their electricity. Under the Renewable scenario, residential electricity prices would more than double by 2050, increasing New England families’ annual electricity costs to $4,610. Bills would rise to $3,339 annually in the Nuclear scenario, $2,302 in the Natural Gas scenario, and $2,569 in the Happy Medium scenario by 2050.
Despite the massive cost of the Renewable scenario, it is the least reliable of the four scenarios studied.
Outgoing ISO-New England CEO Agrees, Renewables Won’t Keep the Lights On
On December 31st, Gordon van Welie —who we are reliably told is a silver fox—stepped down as the President and CEO of ISO-New England. Prior to exiting the stage, he did not mince words about the reliability challenges being posed by public policies in New England.
"We cannot operate the system in the wintertime without a dependable energy source that can balance the system when the sun doesn't shine, and the wind doesn't blow. I think policymakers sometimes lose sight of that fact.”
Mr. van Welie’s statements match very well with the results of our analysis. We found that of the four scenarios we studied—the Renewable, Nuclear, Happy Medium, and Natural Gas scenarios—only the Renewable scenario would have rolling blackouts, while the other scenarios easily meet the rising demand for electricity to power electrified home heating.
After stress-testing the ISO-New England across different weather years and wind and solar output, ISO-NE would experience a six-hour blackout in the Renewable scenario if the hourly wind and solar capacity factors matched those observed in 2019
The other scenarios, however, would constitute what Meredith Angwin calls a “boring” electric grid with no reliability drama. But we ask our readers, where’s the fun in that?
Levelized Cost of Resources
We also conducted our “Always On” Levelized Cost of Energy Analysis to compare the cost of serving load with each energy resource in the scenarios studied.
As we detailed in our previous piece, attempting to meet this heightened demand in the Renewable scenario with offshore wind would cost $436 per megawatt hour (MWh), solar would cost $357 per MWh, and onshore wind would cost $240 per MWh.
Meeting the demand in the Nuclear scenario with small modular reactors and large advanced nuclear reactors would cost $253 per MWh and $185, respectively. It’s important to note that the increased cost of SMRs in the Nuclear scenario is driven by the fact that the units would not be utilized as often, as they are partly used to provide ramping ability to meet peak loads. This is shown in the “ramping” portion of the stacked bar chart.
In comparison, the Natural Gas and Happy Medium scenarios use traditional natural gas peaking resources, thus saving billions of dollars, and there is no need to ramp the SMRs because they can run at full speed.
Lastly, the costs of $46 and $47 per MWh in the Happy Medium and Natural Gas scenarios provide the lowest-cost power to the system.
Conclusion
Of course, each of these scenarios is expensive, so any common-sense individual might question the merits of attempting to electrify home heating and transportation at all, given the huge increases in electricity generation capacity that will only be used for five to six months per year.
We’re not optimistic that New Englanders will exhibit that much common sense. But our hope is that this report can restart the conversation about nuclear and natural gas pipelines in the Bay Area for the first time in a very long time.

ISO New England CEO says region needs firm dispatchable generation by S&P Global

It's interesting, as an MIT alumnus, I recall there being an entire community of incredibly intelligent folks on the campus, all steeped in the realities of physics and how it impacts life, and yet Massachusetts is at the heart of this insanity. this is further evidence, in my mind, of just how much of a cult the climate fanaticism has become.
Good luck to them, but I sincerely hope we don't have to spread the costs of their idiocy throughout the rest of the country
Very interesting and timely article having grown up in Maine in a house with electric heat. I vaguely remember a comment about the electric bill being $3,000.....I believe per year in 1970's $. This lead to measures such as heating only 2 rooms of the house to 68 and everyone having an electric blanket as the rest the house was kept at 60. Similarly, the lack of air conditioning meant several very warm nights each summer with fans to combat the heat and humidity.
I'm curious what the incremental capacity value of the renewables is under the renewable scenario. I'm guessing it would approach the single digit ELCC value I've seen for CASIO leading to massive capacity cost metrics.
Expanding the nuclear resource portion of the portfolio to the point of needing to cycle SMR's is ill-advised given the cost and reliability impact. My initial project in the nuclear space was driven by the temporary belief that we would need to cycle Palo Verde due to increasing solar penetration (driving mid-day load below the capacity of our baseload assets). The analysis prudently focused on an alternate use for the extra capacity/energy (production of hydrogen to use for hydrogen peaking units) as opposed to cycling the plant. My suggestion is that it would be preferable to find alternates loads for excess baseload capacity as opposed to cycling the units.
It seems to me that CAISO New England's current trajectory is directly toward the renewable heavy/electrification scenario, with just a few people starting to speak up with words of wisdom (Gordon van Welie, the groups funding the study). Per last week's article, CAISO New England's customers will be exposed to high cost and reliability risks for years to come......even with an immediate pivot to the Happy Medium portfolio.
