ENERGY PARKS

The document introduces energy parks as a strategy to meet rising electricity demand by integrating wind, solar, and storage with co-located loads like hydrogen electrolyzers and data centers. It outlines the evolution from simple solar farms to complex hybrids and identifies key barriers, including interconnection queues and utility monopolies. The authors propose a 'digital resource' paradigm shift and new state legal frameworks to enable these projects.

• Energy parks are defined as large-scale microgrids that combine generation assets, complementary resources like storage, and co-located loads, all connected to the grid at a single point of interconnection (POI).
• Co-locating loads within energy parks provides several economic advantages, including reduced equipment costs through shared high-voltage transformers, a 2-5% reduction in transmission and distribution losses, and faster 'time to power' by bypassing bulk power system constraints.
• The report identifies a historical evolution of energy parks in three stages: first, using high inverter-loading ratios (ILR) to manage overgeneration; second, the emergence of solar-plus-storage hybrids; and third, the diversification into multi-resource hybrids like the Wheatridge facility, which combines wind, solar, and batteries.
• Hydrogen-producing energy parks are particularly viable due to the Inflation Reduction Act's (IRA) $3/kg production tax credit, which allows projects to super-scale generation to maximize credits during a 'tax-subsidized era' before transitioning to a 'post-subsidy era' dependent on very cheap electricity.
• Thermal batteries can be integrated into energy parks to convert variable electricity into industrial heat, potentially serving 75% of U.S. industrial non-feedstock energy demand and allowing parks to export higher-value energy to the grid while meeting on-site heat needs.
• Energy parks face significant regulatory hurdles, including overwhelmed interconnection queues, a lack of standardized modeling for hybrid resources, and conflicts with state-granted utility monopolies over retail sales and distribution.
• The authors propose a paradigm shift toward treating energy parks as 'digital resources' using a 'universal participation model' that focuses on operational outcomes (like ramp speeds and energy limits) rather than the specific internal technology of the park.
• To resolve monopoly conflicts, the report suggests that state legislatures amend utility codes to allow private ownership of power lines behind a single POI or create pro forma agreements for utilities to accommodate energy parks.
