Milwaukee Will Pursue Data Center Moratorium
Milwaukee is moving forward with plans to implement a moratorium on new data center development. This policy decision represents a regulatory action targeting the data center industry at the municipal level. The moratorium will restrict or pause new facility construction and development permits in the city. This reflects growing municipal concerns about data center expansion, likely related to power consumption, land use, or infrastructure impacts.
Oracle sues Wisconsin over $7B collateral requirement for data centre campus
Oracle is challenging a Wisconsin Public Service Commission ruling requiring it to post more than $7 billion in collateral for power infrastructure serving its 1GW, four-building data centre campus in Port Washington. The utility calculated collateral against net book value of dedicated power plants rather than unpaid bills, creating the country's most stringent requirement. The case signals a new pricing model for hyperscaler risk and reflects broader regulatory pushback against ratepayers subsidizing data centre growth.
OpenAI-Oracle Data Center Project in Wisconsin
Developers have acquired over 1,500 acres in Port Washington, Wisconsin, for Vantage Data Centers to build a campus for Oracle and OpenAI's Stargate expansion. The project, valued at over $15 billion, is expected to be completed by 2028 and create more than 1,000 jobs.
Brookfield-Bloom $25B Financing Bundle Ties Capital to Power Delivery
Brookfield and Bloom have structured a $25 billion financing package that bundles capital with guaranteed power delivery from day one, enabling hyperscalers to advance data-center projects without waiting for utility connections. This strategic shift in capital provision allows projects to maintain schedules while securing energy certainty upfront. The model addresses a critical pain point in data-center development by decoupling project funding from grid interconnection timelines.
