Core Insights - NIPSCO Generation plans to construct up to 3 GW of gas-fired generation and battery storage to support Amazon data centers, with an estimated investment of approximately $7 billion [1][2]. Group 1: Project Details - GenCo will build two 1.3-GW gas-fired power plants and a 400-MW, 4-hour battery storage system for the data centers, while NIPSCO anticipates a non-data center load of about 2.3 GW by 2028 [2]. - The Indiana Utility Regulatory Commission (IURC) approved the GenCo framework to ensure existing customers do not bear the costs of infrastructure for large customers like Amazon [3]. - NIPSCO is expected to start providing power to Amazon data centers by January 1, 2027, with capacity deliveries increasing to 2.4 GW by the end of 2032 [6]. Group 2: Financial Implications - The 15-year agreement with Amazon is projected to generate around $1 billion in savings for NIPSCO's ratepayers, translating to approximately $7 in monthly savings for residential customers [4]. - NIPSCO and GenCo have requested IURC approval for a "special contract" and a power purchase agreement (PPA) related to the arrangement with Amazon [5][7]. Group 3: Infrastructure and Operations - NIPSCO will construct, own, and operate the necessary transmission infrastructure for the Amazon data centers, with costs kept separate from the utility's rate base [8].
