@ElephantEating @JesseJenkins @mackaymiller In Tompkins County we are advocating for the electrification of heat to avoid a new pipeline. Recent study used AEF for converting from ff to heat pumps. Should MEF be used for heat electrification?

Great question! Short answer is that it is complicated and depends on how marginal your new load really is. I think MEF is safely better than AEF, but even that has issues. See this thread I recently wrote on the topic:https://twitter.com/ElephantEating/status/978436206613680129?s=19 …

Eric Hittinger @ElephantEatingA few comments on estimating the emissions effects of electricity use changes (like when we ask what the emissions of charging an EV are). Short version: it is pretty complicated, and I end this with a question mark. Longer: read on https://twitter.com/bradplumer/status/978342252014686209 …Show this thread2 replies 2 retweets 2 likes -
Thanks - very helpful thread. I especially like the idea of thinking about it as marginal new generation over time, instead of simply marginal unit currently.

Remember though: nationally, we are long on generation, load is flat, and RE is being added due to RPS. So new demand rarely triggers new build, rather it changes the dynamics of retirement.

Replying to @mackaymiller @bertbland and
In the short run 'electrification = marginal new generation' is incorrect. For example, in areas with nuclear retiring early (Illinois! upstate New York!) new EV load doesn't equate to new gas+RE, rather deferred nuclear retirement.

But, in the long run, Beneficial Electrification will result in a need for additional generation.
