CRI leads successful effort to prepare Maryland for the widespread use of smart inverters

CRI’s leadership of the smart inverter work group in Maryland’s grid modernization docket has resulted in the adoption of important new interconnection regulations in the State.  Regulations adopted on March 31, 2020 require Maryland’s utilities to propose standard approaches to voltage control and ride-through for smart inverters, and require all inverters installed after January 1, 2022 to comply with the new IEEE 1547-2018 standard.  The new requirements will boost distribution system hosting capacity, help assure the safe and stable operation of the distribution grid, and allow PJM to operate more reliably as distributed generation expands.

CRI Provides Expert Witness Testimony in Smart Inverter Docket

The Center for Renewables Integration is supporting the Natural Resources Defense Council, providing expert testimony in Pennsylvania on smart inverter deployment. PPL Electric Utilities filed a petition with the Pennsylvania Public Utilities Commission in 2019, requesting authorization to require all new DERs equipped with inverters to install communications equipment linked to PPL’s distributed energy resource management system (DERMS). PPL’s request would also authorize the utility to control the inverters remotely at its discretion. CRI witness educates the Commission on risks of that approach and recommends establishing a statewide stakeholder process to determine new smart inverter standards, in line with the National Association of Regulatory Utility Commissioners’ recent resolution, and advocates taking maximum advantage of IEEE-1547-2018 compliant inverters’ autonomous capabilities.
