Oracle is facing a $7 billion cost for powering its AI hub in Wisconsin.

      Oracle is constructing a large AI data center in Port Washington, Wisconsin, in collaboration with Vantage and OpenAI. The Lighthouse Campus, which will nearly reach one gigawatt, represents an investment of approximately $15 billion. However, Oracle must first satisfy local regulatory requirements to obtain the necessary electricity, which is turning out to be costly.

      In a sworn affidavit, Oracle claims that adhering to the regulations would necessitate posting a letter of credit “surpassing $7 billion,” resulting in an annual expense that “might exceed $100 million.”

      Reasons for the regulator's firmness

      In May, the Public Service Commission of Wisconsin tightened the conditions, removing the utility's authority to waive guarantees on a case-by-case basis. It also established an exemption threshold that is difficult to achieve: a credit rating of A-/A3.

      Since then, the commission has “declined to take any action” on Oracle’s request to revisit the ruling, stating to the Financial Times that the regulation is meant to protect current customers. The reasoning is straightforward; a massive data center would utilize the generation capacity of an entire power plant. If it fails to fulfill its commitments, someone has to bear the cost, and the regulator seeks to ensure that it is not the ordinary ratepayers.

      Inopportune timing

      Oracle argues that it is financially robust, although concerns in the market have arisen. On July 9, S&P downgraded Oracle from BBB to BBB-, attributing the change to its AI infrastructure investments and declining cash flow.

      This new rating falls below the A-/A3 exemption threshold and arises as Oracle experiences significant cash outflows. The company has projected capital expenditures of $90 billion to $95 billion for this fiscal year, alongside an anticipated free cash flow deficit of around $42 billion.

      Furthermore, there is an overarching concern regarding OpenAI. S&P estimates that the startup constitutes about half of Oracle’s $638 billion in expected future revenue. If OpenAI is unable to pay, S&P cautions that Oracle may be left with data center leases that remain unoccupied, a default risk that Wisconsin is attempting to mitigate.

      Oracle's proposal

      Oracle is not remaining silent on this issue. Its affidavit contends that firms rated BBB fulfill their obligations 99.87% of the time. It highlights that Oracle stands among the 20 largest companies globally, with approximately $600 billion in equity, and points out that it raised $30 billion in a single day earlier this year.

      In response to the regulatory demands, Oracle has proposed a compromise: posting 10%, roughly $700 million, as a letter of credit and securing the remainder with a parent guarantee. Additionally, the company positions this as a national security concern, arguing that China is advancing more rapidly in grid and AI development while U.S. projects are hindered by bureaucratic hurdles.

      An impending broader conflict

      This issue extends beyond a single data center. As AI data centers proliferate, regulators are questioning who assumes the risk if financial obligations persist beyond the growth phase. Wisconsin's approach is to require the tech giant to provide the collateral rather than the local community. The critical question is whether this strategy protects ratepayers or merely incentivizes builders to relocate to other states.
