Purpose

The bill amends the exemptions to the certificate of need (CON) requirement for energy projects in Minnesota. It adds and clarifies which energy facilities and transmission upgrades can proceed without a CON, aims to streamline permitting, and sets specific capacity and condition-based thresholds.

Main Provisions (What the bill changes)

• Exemption threshold for cogeneration or small power production:
  • Applies to facilities at a single site with combined capacity under 80,000 kilowatts (kW), or any case where federal law preempts the state CON process.
• High-voltage transmission lines serving a single customer/location:
  • Exempts lines proposed mainly to serve a single customer, unless the applicant asks the public utilities commission to determine a need under the CON process.
  • Applies similarly to upgrades raising voltage on existing lines serving a single customer, with an opt-in for a need determination.
• Short connecting transmission lines:
  • Exempts high-voltage lines of one mile or less that connect a new or upgraded substation to an existing line.
• Fuel source conversion:
  • Exempts projects converting the fuel source of an existing electric generating plant to natural gas.
• Efficiency improvements to existing plants:
  • Exempts modifications that increase efficiency as long as capacity does not increase by more than 10 percent or 100 megawatts (MW), whichever is greater.
• Large wind and solar projects (site permits):
  • Exempts large wind energy conversion systems (WEC) and large solar energy generating systems for which a site permit is submitted by an independent power producer under the state’s wind/solar provisions (Chapter 216I).
• Repowering projects:
  • Exempts repowering of large WEC or solar systems if the project does not increase nameplate capacity beyond the most recent interconnection agreement (or, if it does increase capacity, there is a signed generator interconnection agreement showing the expected net power increase).
  • This involves the Midcontinent Independent System Operator (MISO) processes and interconnection agreements.
• Energy storage systems:
  • Exempts energy storage systems from CON requirements.
• Transmission lines directly interconnecting WEC/solar/storage to the transmission system:
  • Exempts lines that directly interconnect these facilities to the wider transmission system.
• Relocation of HV transmission lines:
  • Exempts relocation of an existing HV line to a new right-of-way (ROW) as long as new structures are not designed for and cannot operate at higher voltage.
• Upgrading/rebuilding lines to 115 kV:
  • Exempts upgrading or rebuilding an existing electric line to 115 kV from less than 100 kV, if the upgrade primarily uses existing ROW.

Definitions and Clarifications

• Repowering project:
  • A project for large WEC or solar systems that increases efficiency without increasing nameplate capacity, or involves replacing turbines or other changes that increase capacity.

Significant Changes to Existing Law

• Expands and specifies multiple categories of energy projects that do not require a CON, including certain cogeneration, wind/solar, energy storage, and specific transmission work.
• Introduces capacity thresholds (e.g., 80,000 kW; 10% or 100 MW) and interconnection requirements that determine whether an exemption applies.
• Ties exemptions to interconnection agreements and MISO processes for repowering and capacity increases.
• Requires consideration of federal preemption where applicable; certain exemptions may be affected if federal law preempts state processes.

Potential Impacts

• Accelerates approvals and development for many energy facilities and upgrades by reducing or waiving CON requirements.
• May shift more project review to other processes (site permits, interconnection agreements, MISO coordination) and rely more on private/independent planning.
• Could affect regulatory oversight, project timing, and reliability considerations for certain energy projects.
