CenterPoint Energy advances networked geothermal pilot project to support year-round customer energy needs and Minnesota decarbonization efforts

As part of the Company’s efforts to implement its innovation plan, CenterPoint Energy has selected the joint team of Resource Innovations and Salas O’Brien to help advance the company’s networked geothermal pilot project, supporting site selection and the system feasibility study. The joint team brings expertise in developing utility thermal energy network strategies and networked geothermal and district energy systems, including in Minnesota.

A networked geothermal system can provide heating and cooling to multiple residential, commercial and public buildings connected by underground water pipes and electric heat pumps, using the relatively constant temperature of the earth. This system will be designed to pull warmth into buildings in colder conditions and provide cooling by pumping heat into the ground during warmer weather.

“CenterPoint looks forward to developing our first networked geothermal system in Minnesota to demonstrate how this technology could support customers in both winter and summer while helping meet the state’s decarbonization efforts,” said Brad Steber, CenterPoint Vice President, Minnesota Gas. “We remain committed to advancing innovation for Minnesota’s energy future, while maintaining safe, reliable and resilient energy service for the customers and communities we’re privileged to serve.”

Since launching this pilot in late 2024, CenterPoint has been working with local governmental entities to garner interest in collaborating on this project. Over the coming months, CenterPoint expects to conduct siting and modeling efforts to identify a preferred site.

In addition to this pilot project, the company is offering incentives for large customers to partially offset costs to research, install and operate their own networked geothermal systems, as well as seeking opportunities to decarbonize existing district energy systems in a community CenterPoint serves.

CenterPoint’s innovation plan

This project is part of CenterPoint’s five-year innovation plan submitted under Minnesota’s Natural Gas Innovation Act (NGIA). The NGIA enables natural gas utilities to invest in renewable energy resources and innovative technologies to help reduce Minnesota’s greenhouse gas (GHG) emissions.

The Minnesota Public Utilities Commission approved CenterPoint’s innovation plan in 2024, which includes 17 pilot projects and seven research and development efforts. This innovation plan is expected to reduce or avoid an estimated 1.1 million tons of carbon emissions over the lifetime of the projects – equivalent to the annual energy use of approximately 150,000 homes.

CenterPoint is committed to helping residential and business customers reduce GHG emissions attributable to their end-use of natural gas by 20-30% by 2035 (from a 2021 baseline). The company’s innovation plan is designed to support customers in reducing emissions from their own energy use.

Net Zero Disclaimer

CenterPoint Energy’s Scope 1 GHG emissions estimates are calculated from GHG emissions that directly come from its operations. CenterPoint Energy’s Scope 2 GHG emissions estimates are calculated from GHG emissions that indirectly come from its energy usage, but because Texas is in an unregulated market, its Scope 2 GHG emissions estimates do not take into account Texas electric transmission and distribution assets in the line loss calculation and exclude GHG emissions related to purchased power between 2024E-2026E. CenterPoint Energy’s Scope 3 GHG emissions estimates are based on the total natural gas supply delivered to residential and commercial customers as reported in the U.S. Energy Information Administration (EIA) Form EIA-176 reports and do not take into account the GHG emissions of transport customers and GHG emissions related to upstream extraction.  CenterPoint Energy’s analysis and plan for execution to achieve its Net Zero GHG emissions (Scope 1 and certain Scope 2) by 2035 goals and its 20-30% reduction in Scope 3 GHG emissions by 2035 as compared to 2021 levels goal require it to make a number of assumptions. These goals and underlying assumptions involve risks and uncertainties and are not guarantees. Should one or more of these underlying assumptions require updating, CenterPoint Energy’s actual results and ability to make progress towards and achieve its Net Zero and GHG emissions reduction goals and the timing thereof could differ materially from its expectations. Certain of the assumptions that could impact its ability to make progress towards and meet its Net Zero and GHG emissions reduction goals and the timing thereof include, but are not limited to: GHG emission levels, service territory size and capacity needs remaining in line with company expectations (including with respect to demand for our services); the ability to appropriately estimate and effectively manage business opportunities from new customers and load growth resulting from, among other things, expansion of data centers, energy export facilities, including hydrogen facilities, electrification of industrial processes and transport and logistics in our service territories; regulatory approvals related to Indiana Electric’s generation transition plan and CenterPoint Energy’s ability to obtain such approvals; impacts on affordability of customer rates; customer demand for GHG emissions free or lower GHG emissions energy; impacts of regulations, executive action or legislation, including those related to the environment and tax matters (including the effects of the One Big Beautiful Bill Act, Executive Order 14315 and the Inflation Reduction Act (IRA) and any further changes to or the repeal of the IRA); impacts of future carbon pricing regulation or legislation; price, availability and regulation of carbon offsets; price of fuel, such as natural gas; cost of energy generation technologies, such as wind and solar, natural gas and storage solutions; adoption of alternative energy by the public, including adoption of electric vehicles; rate of technology innovation with regards to alternative energy resources; CenterPoint Energy’s ability to implement its modernization plans for its pipelines and facilities; the ability to complete and timely implement generation alternatives to Indiana Electric’s coal generation and retirement or fuel conversion dates of Indiana Electric’s coal facilities by 2035; the ability to construct and/or permit new natural gas pipelines; the ability to procure resources needed to build at a reasonable cost, the lack of or scarcity of resources and labor, the lack of any project cancellations, construction delays or overruns (including as a result of tariffs, legislation, bans, potential retaliatory trade measures taken against the United States or related governmental action) and the ability to appropriately estimate costs of new generation; impact of any supply chain disruptions; changes in applicable standards, metrics, methodologies or frameworks; and enhancement of energy efficiencies.
