​Minneapolis – Nov. 1, 2023 – CenterPoint Energy filed an application with the Minnesota Public Utilities Commission (the “Commission") today requesting an adjustment to delivery charges in 2024 and 2025 for the company's natural gas business in Minnesota.

Known as a rate case, the proposed adjustment would help the utility not only comply with required federal regulations but also make meaningful investments to decarbonize and continue the safe and reliable operation of its 14,000-mile pipeline system. As the largest natural gas utility in Minnesota, CenterPoint Energy delivers energy to more than 910,000 residential and business customers in Minnesota.

“Our customers and communities benefit from the meaningful investments we make into our natural gas distribution system," said Christe Singleton, CenterPoint Energy's Vice President, Minnesota Gas. “The rate case is based on the need to maintain a safe, reliable system that delivers the essential and increasingly clean energy our customers count on each day, especially the coldest days."

Singleton added, “We're excited about the Natural Gas Innovation Act plan that we filed with the Commission this past June as part of our commitment to evaluating innovative solutions that help reduce emissions to support a cleaner energy future. Our innovation plan will increase access to renewable energy resources and innovative technologies such as the CarbinX technology that helps our customers reduce their onsite emissions. This rate case filing proposes to recover certain costs associated with the plan."

CenterPoint is committed to innovative, comprehensive solutions that reduce greenhouse gas emissions and advance Minnesota's cleaner energy future. In 2022, CenterPoint began producing green hydrogen, which is hydrogen made with renewable electricity, to blend it into natural gas at low levels of concentration for delivery to customers in Minneapolis. An additional project, proposed within its innovation plan, would produce renewable electricity on site for hydrogen production.

The requested increase is approximately 6.5% or $84.6 million for 2024 and an additional approximately 3.7% or $51.8 million for 2025. If approved, the requested increase would add $5.91 to a typical

residential customer's monthly delivery charge in 2024 and an additional $2.58 to a typical residential customer's monthly delivery charge in 2025. The delivery charge accounts for roughly 40-50% of a typical residential customer's monthly bill.

The rest of a customer's bill is the cost of natural gas which is passed through at cost. CenterPoint Energy does not mark up or profit from the purchase or sale of natural gas. For the 2023-2024 winter season, natural gas costs are estimated to be lower than the 2022-2023 winter season, assuming normal winter weather, that would flow through to mitigate customer bills.

CenterPoint Energy is asking the Commission to review and approve the proposed new rates, which are likely to occur in early 2025. A proposed interim rate increase of approximately 5.3% would take effect on Jan. 1, 2024, while the rate case is pending. Additionally, an interim rate would apply starting on Jan. 1, 2025, for an additional 2.4% increase.
