It plans to add 18,000 square feet to its lease at the site in January 2027. The company also repeated earlier benchmark claims against single-phase cooling and said a 375 kW-capable multi-rack unit will follow the MR250, with details still to come. The benchmark and energy figures are vendor claims.

The company's own release claims up to 40% lower compressor power at the same cooling capacity. That figure is a manufacturer claim and the release does not state the rating conditions behind it.

NiSource's generation company will add about 1,100 MW of new generation resources, and Microsoft funds the generation and transmission needed to serve its load. In connection with the deal, the generation company has contracted 600 MW of battery storage under a long-term tolling agreement, to be built by an AGP Group affiliate. NiSource says the structure raises expected savings for existing NIPSCO electric customers to about 1.75 billion USD over the life of its data centre contracts. That savings figure is the utility's own estimate.

DCD later added an account from a source familiar with the project: the transformer fire was in December 2025 and destroyed switchgear, temporary generators kept the cooling running, the leak was fixed within weeks and the cooling system was completed more than three months ago. That source accepted there was an overall delay. DCD reports 6.4 MW of a planned 30 MW is operating. Nscale had not commented to DCD at the time of publication.
