EVOLVE on-demand: The Rate Design Ripple Effect: From Customer Bills to Project Economics

Wednesday, June 3, 2026
12:00 AM | Central Time

Webinar details

Electricity rates were flat in real terms for 15 years. That is ending. 

Rising transmission and distribution costs, supply chain pressure on generation equipment, and load growth running five times faster than previous decades are pushing rate trajectories upward in ways that vary sharply by geography and customer class. For developers, large energy buyers, and utilities, the implications run well beyond customer bills. Rate structures shape PPA competitiveness, procurement appetite, and which generation projects pencil out. 

At EVOLVE 2026, Doug Lewin (Energy Markets Development, Texas Lead at Google), Sam Newell (Principal, The Brattle Group), and Margarita Patria (Principal, Charles River Associates) examine where rate design is heading and what it means for every stakeholder in the power value chain. 

What you’ll learn:

  • Why electricity rates are rising now after 15 years of real-term stability, and which geographies are seeing the sharpest increases
  • How new large-load tariff classes are being structured for data centers, with long-term contracts, minimum demand charges, and collateral requirements that vary by state
  • How rate design decisions ripple through PPA terms, procurement appetite, and project economics
  • Why some states are actively courting data center investment while others are imposing conditions that create significant financial exposure for large loads
  • How grid-enhancing technologies, dynamic line ratings, and demand flexibility can slow rate increases by improving system utilization
  • Why demand growth running at five times historical rates is creating stranded cost risk and complicating supply chain planning for utilities
