Alliant Energy asked the Public Service Commission to approve an individual electric service contract with Meta affiliate Degas LLC covering 220 megawatts of power for the Beaver Dam data center over a 10 year term. Regulators approved it on May 7, 2026 but criticized the secrecy around the filing, including nondisclosure agreements, heavily redacted documents and a corporate pseudonym, and said they want less of a black box approach and longer contract terms in future cases. Alliant says the deal makes Meta cover the full cost of serving the site so other customers are not harmed.
What it means for your bill: Meta says the contract means other Alliant customers will not pay for the energy used by its Beaver Dam data center, though consumer advocates say the secrecy around the deal makes that hard for the public to independently verify.
