A heat pump is also coming in but let's get real it probably breaks even with a CCGT that isn't recovering steam. But it's straight up displacing a heat recovery steam gen which is powered off waste heat which is the worst thing you can displace...

A poster child for virtue signaling bad incentives?

Tbf that's not looking great either. And they are replacing a heat recovery stream turbine with electric resistance boilers at the Kendall cogen site 🙈

Man I thought this nonsense would go out with Gillett lol

Yeah come to think about it inducing electrical demand when an RFO burning steam plant is on the margin is crazy

My wild EE idea is that we need to have more competition for heat pump installers to bring price down...allow people to diy minisplits in the program for rebates like with mr cool?

If you save more in energy from the EE investment over the lifetime because infrastructure cost is recovered volumetrically than you save in the system reducing costs to serve by reducing peak needs then the cost shift is to all other ratepayers.

Fwiw ai says inflation was 1.5x

I mean insofar as the volumetric savings dont overwhelm the capacity savings right otherwise it too is a cost shift

Inflation has been high but come on tripling in 15 years massively outstrips that. It's gone from being a technically focused program to a boondoggle for the contractors

And we are probably paying for the RPS both and net metering and in the supply charge itself right.

Counterpoint the fact that energy efficiency spend and and net metering add up to transmission is wild and that net metering recovery surcharge seems to be shooting up
What was the level of energy efficiency funding in the early 2010s.

Vibes over substance for sure. Both sides are guilty of this

I don't disagree this seems rather extraneous.

But seriously shouldn't there be a condition that they should build for the minimum of safety and any extra consideration like aesthetics should be funded by the community. Looks like East Boston got a shakedown at the costs to the rest of us.

It's also wbur so the objectivity here is shall we say...questionable.

Of course the ratepayers are on the hook for it. Thats how it works right? That's part of the capital spend if you want to blow up the costs with requirements

I'm sure the city had a big say in making them do it tho and if they were getting paid anyways why not. Of course fighting this for ten years and blowing out those costs didn't help either...

I had missed at at first because it was so far away from what I had expected. I was thinking I would be able to see the transformers from the street!

Yeah tall poles in the tent are still pipelines and nimbyism for build right. I went by East Boston substation the other day and I wondered if they needed to make it look like a housing complex. I had almost missed it at first...
