You can't magic up that extra generating capacity out of nowhere. It takes years to approve, design and build more by which point the miners will be long gone and they're left with a load of capacity doing nothing.
It's better to price the shit out of the miners or simply tell them to go away and not come back than have daily life fall apart. I can see a time when miners finance their own power generation facilities. I don't think mining and regular generation will coexist for long.
I would call this an opportunity for the local authority there to start their thinking engine inside their minds and find out a solution rather than increasing the electricity price.
Impose clean energy for new miners?
3 years to switch to clean energy for the already installed ones?...
This will benefit everyone.
The reason electricity is so cheap in WA is because of all the hydroelectric (clean energy) capacity there, so the clean energy angle is probably moot.
When miners push the grid beyond capacity, they increase the electricity price
for everyone else. It makes no sense to only view things as if the miners are helpless victims being punished by utilities.
Businesses (including mining businesses) actually pay less than residents. On average, Washington businesses pay 7.68¢/kWh while residents pay 8.53¢/kWh. Businesses are already receiving significantly subsidized electricity costs vs. residents. Why should that be?
What do these localities gain by having miners set up operations? It only makes sense to incentivize businesses if they actually help local economic growth and prosperity. If they are increasing costs of living for everyone else -- and this is the primary concern in all of these cases -- it makes sense to stop subsidizing them and to disincentivize them from operating in the first place.
Does Ephrata receive tax revenues, and how significant are they? Are miners contributing to the local economy, or do they simply drive up everyone else's electricity costs and give back nothing? If I lived there, I would only take a pro-mining stance if there were benefits for me and my community. It's irrational to take a blindly pro-miner stance because it would only mean higher electricity costs for me, and possibly an unreliable electrical grid.
