On Subsidizing Millstone

July 2020 was the month that a lot of Connecticut residents noticed a significant increase in their electricity bills. The reason turns out to be that CT's Public Utilities Regulatory Authority (PURA) approved (and the governor signed) in September 2019 a requirement that Eversource and United Illuminating - CT's two major power providers - purchase electricity from the financially-torn Millstone Nuclear Power Plant.

Of course, as soon as everyone saw their monthly bills increase - about 7c/kWh or almost 50% - the screaming started and "investigations" were called for and as of this post it is rumored to get rolled back, at least temporarily:

The idea of subsidizing Millstone seems to grate on a lot of people's nerves, especially given the significant diametric positions many have on nuclear energy.

But let's go back and read a quote from the opening paragraph in that first link:
“Had this contract not gone forward, the facility would be in danger of closing down which would have increased greenhouse gas emissions by 25 percent across the New England region,” Governor Lamont said. “This important step keeps Connecticut and all of New England from back sliding on addressing climate change. Now we can renew our focus on offshore wind and other renewable energy resources to fully transition to a clean energy grid by 2040.”
(My emphasis...wow, something I agree with Lamont on...is that bacon flying overhead...?)

The one thing we're forgetting about all this: the societal value of keeping Millstone Nuclear online.

How many of us have thought (or declared) that we're willing to pay extra for energy to support sustainable sources like wind and PV to replace fossil fuels? Probably a lot of us. Maybe most of us. And subsidizing energy from Millstone is a step in the direction of an environmentally-friendly future.

Wait, wut? Yep.

What's the biggest problem with PV and solar? It's inconsistent. You are highly unlikely to get power from it at night (zero chance with PV) so you either need energy storage for use at night or alternative sources of energy. The technology for macro-scale storage solutions are way, way off right now* so the other alternative sources of energy are fossil fuel-based. If we want to transition to larger-scale PV and wind, then off-peak generation has to be by these fossil fuels: natural gas, oil, and coal. All exhaust carbon.

But wait...what about Millstone Nuclear? It's carbon-free, just sits there making power -- and it's already there. With nuclear, we could throttle it down during the day when we're generating with PV and wind, and when the sun starts to go down we throttle it back up to provide nighttime energy. In the meantime, technology advances toward true macro-scale energy storage solutions. There is no other environmentally-friendly carbon-free alternative right now.

But due to regulations, nuclear energy is expensive (long gone are the days of "too cheap to meter"); Millstone is losing money, and is at risk of being shut down. If we let it shut down, then its output will have to be replaced with carbon energy. So unless we drop our concerns with its existence (or allow more installations using newer technologies) nuclear is not getting any cheaper. Further, Millstone's life is finite; each plant has a regulated licensed life limit (I believe Millstone 2 is 2035, and Millstone 3 is 2045; Millstone 1 is already shut down). So the clock is ticking...

If your end goal is carbon-free environmentally friendly production of energy, you'll never get there unless/until the technology is developed for reliable, affordable macro-storage -- or you embrace nuclear. Otherwise we have to use more fossil fuel.

You've declared that you're willing to pay more to get to environmentally-friendly/sustainable energy. Subsidizing Millstone is an effective, immediate transitional step toward that environmentally-acceptable future. Let's embrace it.

08/04/20 Edit: Another factor in Connecticut spiking energy costs is the state's decision to adhere to stringent Renewable Energy Portfolio Standards.

"Green energy" ain't (yet) cheap energy...

*A nice "battery" solution is the old, but still functional, Rocky River Pumped Hydro Station along Route 7. The lake was created when they damned up the Rocky River to create the pumped hydro facility, creating Candlewood Lake.

"Pumped hydro" uses turbines powered by the cheaper overnight off-peak energy to pump water from the Housatonic River up into Candlewood Lake; during the day the plant releases water down from the lake to drive the same turbines to generate power and sell it back at the higher day rate. Its efficiency is incredible, exceeding most other storage sources, and Rocky River is still functional nearly a century later.

It's a big energy battery.

To support PV and wind, that concept can be turned up to 11: we could use excess PV/wind-generated energy during the day to pump the water up into the lake, then at night drain the water to generate electricity when PV/wind cannot.

Alas, that particular station - the first ever pumped hydro in the USA, I believe - is not big enough for the electrical loads that we'll all need at night, and there's just no way in Hades anyone would ever get approval to build another one today. So...off to further development of chemistry battery technology we go...

Thank you for your rapt attention on Yet Another Greg Rant. Time for beer.

An Interesting GTSB (Greg Transportation Safety Board) Report

An Interesting GTSB (Greg Transportation Safety Board) Report (Subject to revision) On August 29, 2024, at approximately 6:30PM (EDT), the engine in the #33 Porsche 914 suddenly stopped as it was slowly driving away from the town green of Falls Village, CT. Hearing a large noise (discernable by nearby onlookers), the driver immediately disengaged the drivetrain via the foot clutch and car coasted to the side of the street. Initial attempts to restart the engine were met with a starter that would not rotate; attempts to push the car while the transaxle was engaged were met with full resistance. It was quickly determined that the engine had locked up. After minimal roadside investigation, it was determined that the dry sump tank oil valve, which supplies oil to the engine oil pump, was in the closed position and it was obvious that the engine had been run without a supply of oil. As a result, the car was "flat bedded" back to Lime Rock Park and retained as a paddock display for...

On "Microsquirting" the Porsche 914

Bosch D-Jetronic The Bosch D-Jetronic system is pretty cool, especially when you consider it was designed in the 1960s. "Computer"-controlled electronic fuel injection with manifold pressure sensor, intake temperature sensor, crankshaft (well, distributor) angle sensor, and throttle position sensor/switch. It uses constant fuel pressure and flow, so only injection duration needs to be modified to control air/fuel mixture. It measures incoming airflow by monitoring the intake manifold pressure; engine speed, temperature, and other factors are monitored for the purpose of fine-tuning injection duration. Ignition is by a standard cam-driven distributor with an internal D-jet-specific pickup for the crank/cam angle position. This "speed-density" D-Jet system was used on many cars of the period, including Volvo, Jaguar, Volkswagen, and of course, the Porsche 914 (1.7L and 2L engines only; the 1.8L used L-Jetronic -- "L" for "luft" or "air...

On "Accusumps"

(This is another blog in a series of thoughts/ideas that I commonly see, created as a placeholder for future reference so I don't have to re-write it each time. I totally understand the limited audience and for such a post, but I invite feedback from those who have interest in this arcane subject...) -------------------------------------------------- This was posted in response to someone inquiring about PDM control, pressure sensors, switches, valves to manage an Accusump in his race car... You're making this wicked too complicated...and significantly failure-prone. An Accusump (AS) is a passive hydraulic/mechanical oil pressure accumulator (thus, "Accu"sump). Its purpose* is to provide oil flow when the pickup tube in your engine becomes unported due to side loads oil "slosh" or flow away from it. First, note that an AS is a "BandAid" for a design flaw in your road race engine. That design flaw is the unporting of the oil pickup. The ultimate res...
