Duke Energy Indiana's $103 Billion Capital Plan Is Already in Your Bills
The IURC approved new Duke Energy Indiana rates in early 2025, adding roughly $295.7 million in annual revenue. For customers, that works out to an overall average bill increase of about 11%, phased in as approximately 8% in February 2025 and another 3% in early 2026. Duke had originally requested around $491 million. The OUCC recommended a lower number. Duke has filed for reconsideration, so that rate case is not closed.
Duke's five-year capital plan totals $103 billion across its six-state footprint, the largest of any regulated utility in the U.S. Duke's CEO has said publicly that hyperscalers are required to cover their own infrastructure costs under Indiana's "growth pays for growth" framework. The stated position is that your rate pressure is coming from grid hardening and transmission investment, not from subsidizing data centers. Watch Duke's reconsideration filing and any new rate case that follows, pay particular attention to how C&I tariffs are structured relative to residential and large industrial rates.

- Q
Given Duke's $103 billion capital plan and ongoing rate case activity, how accurate are our three-to-five-year energy cost forecasts?
Duke's rate increases are not finished, the utility has filed for reconsideration and its capital deployment runs through 2030. If your facility-level forecasts assume flat or modest rate growth, they are likely too optimistic. Build your scenarios around the high end of any reasonable range.
