IIRC the heat pump is water source so the economics are probably better than you might think, but yeah, still not sure why displacing cogen makes any sense

Haha the electric resistance boiler thing does see crazy to me. Aren’t they also supplementing that with a HP?

Anyway get ready cause a lot more funding for this is coming (though not ratepayer funded... for now...): portal.ct.gov/deep/energy/...

it's certainly crazy if what you care about is affordability, reliability, etc., but that's not the policy goal of that of course. its craziness from a decarb perspective depends on your assessment of what the marginal gen looks like for the ~15 years AFTER the HP install :)

I would still argue that MOSTLY heat pumps aren’t EE! They’re building decarb… which is not a resource alternative!

Oh you mean participant to non participant cost shift. Sorry couldn’t get that through my head though it is in retrospect obvious. Yes, absolutely true

So maybe “closer to double” wasn’t fair but it’s a big impact regardless

Yeah my quick math was 1.5 bil in 2010 spend is about 2 bil in 2025 dollars

Hm I’m not sure I’m following the cost shift thread… cost shifts to who? Regardless I think this is generally a non-issue for actual traditional EE programs for which you would define your benefit cost screens to account for this

Oh of course it outstrips that I wasn’t trying to attribute it to inflation haha. It’s just closer to double than triple when you take inflation into account

Yeah probably. As I think we’ve covered before I think actual EE (which a ton of massave spend still covers) is pretty different than RPS stuff. Actual EE (not heating fuel switching) is just a cheaper resource alternative!

The first MassSave plan was 1.4 billion from 2010-2012 (prior to that EE was individually run by utilities), so we’ve tripled or so in the last 15 yrs, though if you adjust that for inflation it’ll take out a sizeable chunk

I *am* in favor of making the emissions targets nonbinding though, Vermont is going through it right now with lawsuits about their versions of the GWSA and there's just no way that getting lawyers paid on this stuff is helpful

While I wouldn't call it nutty, I remain personally of the opinion that we should not be providing efficiency rebates for new customer-sited equipment that actually uses natural gas (e.g. condensing furnaces), though there are good arguments on both sides for that point.

To be fair I always like to read energy media that misunderstands the root causes of what the problems are because if anything it just makes my points better for me!

article suggests that Eversource bait and switched on the "community benefits agreement" but again it's old so IDK. I've never seen anything like this before!
