Talen Energy has completed construction of its first data center building in close proximity to its nuclear power plant in Pennsylvania (USA). According to DataCenter Dynamics, the first stage of the data center with a capacity of 48 MW and an area of almost 28,000 m2 is ready to receive the first customers. The area of the entire Cumulus Susquehanna campus is about 485 hectares, and the total capacity of the data center will be about 475 MW. The campus is expected to house hyperscalers and crypto mining companies.

The capacity of the Susquehanna Steam Electric Station nuclear power plant (2.5 GW) can also be supplemented with 400+ MW green solar power plants. The construction of two facilities on the territory close to the nuclear power plant was started in 2021. To do this, Talen Energy formed the Cumulus Growth structure in 2020 to invest in two types of activities: the Cumulus Data division is responsible for the hyperscaler data center, and Cumulus Coin, together with TeraWulf, for cryptomining. Talen promises to help customers achieve zero carbon footprint with a carbon-free data center platform in Pennsylvania.

This is not the only company implementing data center projects directly related to the use of nuclear energy. For example, last year Microsoft signed a Power Purchase Agreement (PPA) with Canada's Ontario Power Generation, which owns the nuclear power plant. Blockchain company Standard Power, which already receives energy from Energy Harbor in Ohio (USA), intends to build a 900-MW campus near the Beaver Valley nuclear power plant (Pennsylvania, USA).
