EPA: Data Center Power Can Bypass Pollution Rules
EPA says power for data centers can sidestep pollution laws
The U.S. EPA issued guidance clarifying that the Clean Air Act's Acid Rain Program does not apply to "islanded" power generation facilities—those not connected to the public grid. This move, aligned with President Trump's Ratepayer Protection Pledge, gives data center developers more flexibility in building new facilities while aiming to protect communities from utility price hikes. The guidance expands opportunities for companies to power data centers with their own generation, potentially sidestepping certain pollution regulations.
Ensuring that the United States maintains our artificial intelligence dominance is essential to national security and economic prosperity.

> Clean Air Act (CAA) Acid Rain Program (ARP) does not apply to power generation facilities that are not connected to a public electricity grid, commonly referred to as “islanded” power generation facilities.
This of course makes no sense whatever, as whether or not a power generator is connected to the grid has nothing to do with its environmental impact.

Hmm... rules for thee but not for me. Sounds like the beginning of the end for the EPA. Two tiered rules breed resentment. There are already plenty of people that don't like the EPA. Making exceptions just makes it easier to argue the EPA is useless or just a tool for oppressing the little guy.

What a disgrace. Abysmal leadership in this country.

There are big benefits to having power generation grid connected.
It is more reliable (due to many possible generation sources). It is more eco-friendly (solar in daytime, wind when the wind blows). It is more cost efficient (no need to overbuild for peak usage, generators don't sit idle when computers are off for maintenance).
Yet our electricity grid has such a mass of regulations attached that people are choosing to lose these benefits - and with it we lose the benefit of them connecting to our grid.

Surely this is going to cement the reputation of datacenters as a blight.

What's frustrating is that the title in this thread is very misleading. This is the way the laws have been: Separate laws for generators feeding into the grid.
Why this is, I don't know. I suspect it's because the vast, vast, majority of non-connected generators were, (until now,) backup generators that only ran occasionally. I even have a "fancy" portable generator in my garage that probably emits way more pollution per kwh than a typical fossil fuel plant, but I probably only run it ~10 hours a year at most.
What's more disappointing is that this loophole is being promoted instead of closed; but everyone here seems to think that laws were weakened.
