Our paper (@MatthiasFripp @imelda_econ) on how much real-time pricing lowers the cost of clean energy integration in Hawai'i was finally published in AEJ Policy.
Cleaner is cheaper, especially with RTP!
So why can't we just do this?

I don't know who needs to hear this, but even if we were all gung ho on direct air capture of CO2 and could do it for less than the social cost of CO2 emissions, that doesn't mean we'd want to continue business as usual and just pay for DAC on the back end. /1

This makes sense because these changes are—by definition—cheaper than DAC. Why emit at current rates and then pay $160-$200/tCO2 to clean up all those tons, when you could avoid them at a lower cost by building a better power system? /3

👀This isn't just about electricity planning models.
It's an intercomparison of4⃣open-source, state-of-art models, and a data pipeline that feeds them. Replicable, extensible.
There's more coherence and similarity in findings than any intercomparison I've seen.
RSVP!
Join our virtual #ClimateWeekNYC event next week to learn how electricity planning models work and how they can play a part in our journey to 100% clean energy 💡. RSVP: mailchi.mp/edf/modeling-clim…

The NYC Climate Week event will present our work with researchers from @Princeton, @CarnegieMellon, @UHawaiiNews & more to make these models more approachable and demystify this type of modeling. mailchi.mp/edf/modeling-clim…

This is a great idea, so great that I am aware of multiple companies looking to bring something like this to market, such as VoltQuant or Yottar.
Lack of grid capacity is already a key barrier to deploying renewables & electrification.
A solution: grid hosting capacity maps.
Here's our @RegAssistProj @EmberClimate proposal for what this could look like in Europe 👇

Berkeley folks: Read this excellent thread and pls email Berkeley City Council; details in thread. Having just returned from London where I deeply appreciated how much housing density is LIFE—in the streets, for small businesses, for safety, I strongly endorse the new plan.

Huge but under-appreciated issue: As gas demand is expected to fall what do we do with the gas grid?
Regulators increasingly consider accelerated depreciation of gas pipes. This means paying off the gas grid early to avoid stranding of assets in the future and allow for decommissioning.
@ofgem has just decided that rather than using a usual 45 year depreciation timeline future gas grid investments will be depreciated by or before 2050. This may also apply in the future to all existing gas pipes rather than just new investments.

A wonderful example of how jacked the incentives of the regulated-utility industry:
1. Generators tell the utes: "Listen, we will pay up front all the money you say you need to interconnect us to your grid"
2. Ute, returning check: "No. We insist on financing these projects."

A reminder to nuclear supporters. You can only have 2 of the following 3 things:
1. deep decarbonisation of electricity using mostly nuclear
2. no reliance on storage to manage variability of demand & supply
3. a nuclear fleet with high capacity factors

Fusion powered SMRs are scaling faster than any other source of electricity in history.

Important thread from @tylerhnorris showing the unfair treatment of solar by utilities: no capacity credit for RA, but then required to be deliverable in the interconnection process (NRIS). So solar pays for network upgrades but gets no RA credit. Not right.
Anyone know how hard it would be for oil companies to switch from mainly making fuels to mainly making chemicals? I think this means producing much less fuel or switching to using it as a feedstock, e.g., for plastics. Could this run on electric heat? Thinking of CO2-free world.
