Powering Progress: Decarbonization Efforts Expand in 2025 as Utilities Prepare for Data Centers

The latest quarterly update from the NC Clean Energy Technology Center (NCCETC) unveils the Q1 2025 edition of its influential 50 States of Power Decarbonization report. This comprehensive series tracks the evolution of clean energy objectives, emission reduction initiatives, generation planning, and shifts in electricity generation across the nation—including through measures such as green tariffs and facility retirements. New to this quarter’s analysis is a detailed section spotlighting how data centers and other high-demand users are reshaping resource procurement, grid connections, and bespoke tariffs.

Key Figures from Q1 2025: Regulatory Action and Legislative Highlights

Throughout the first quarter of 2025, 48 states plus Puerto Rico enacted 293 distinct measures targeting power sector emissions reduction and strategic planning, while an additional 429 bills had been introduced but had yet to clear a legislative chamber. Importantly, this quarter marks a shift in tallying actions: only passed legislation and regulatory developments are counted, while introduced bills are cataloged as supplementary material for deeper review.

When examining resource plans submitted or pending with state regulators, the energy landscape shows targeted growth in generation: 92,592 megawatts (MW) are slated for new natural gas capacity, 88,858 MW for solar deployment, 49,367 MW for wind, and 34,861 MW for energy storage, offset by 41,921 MW of planned coal plant retirements.

Dissecting the Trends: Shifting Dynamics in Decarbonization

• Three significant themes dominate this quarter’s report on the momentum of electric power decarbonization:
• Some policymakers are advocating to roll back established goals for energy and emissions.
• Utilities are crafting dedicated tariffs designed for the burgeoning needs of data centers and large-scale customers.
• There’s a pronounced push from both utilities and lawmakers to expand natural gas infrastructure.

“This marks the inaugural quarter since 2023 in which natural gas tops the list of planned resource additions in utility Integrated Resource Plans,” remarks Autumn Proudlove, Managing Director of Policy & Markets at NCCETC. She notes that this pivot is in direct response to utilities adjusting their demand forecasts in light of the anticipated surge from large tech facilities and similar enterprises.

Pivotal Policy Developments from Q1 2025

Several major milestones define this quarter’s policy arena:

• 1. Regulators in Indiana and Nevada have authorized new data center-specific tariffs.
• 2. Georgia Power has advanced its 2025 Integrated Resource Plan.
• 3. Hawaii’s Governor has issued an executive directive focusing on carbon neutrality at the county level.
• 4. Missouri’s legislative body has codified resource planning statutes.
• 5. Maine’s Governor’s Energy Office rolled out the updated Maine Energy Plan alongside a technical roadmap for implementation.
• 6. Refining the Approach to Large Load Customers

Reflecting on the sharp rise in projected energy consumption from data centers last year, utilities are responding by devising innovative tarifs and contractual mechanisms for these large consumers. “By introducing these specialized tariffs, utilities hope to catalyze investment in clean technologies, fortify grid reliability, and safeguard residential and small business customers from unfair cost redistribution,” says Justin Lindemann, Senior Policy Analyst at NCCETC. 

This adaptive strategy underscores a commitment to balancing the demands of a rapidly evolving digital economy with ambitious sustainability targets.
