MISO wins approval for new rules to link up external transmission

Midcontinent Independent System Operator can change its rules to help pave the way for merchant high-voltage direct current transmission projects, a technology that could help move large amounts of renewable power over long distances, federal regulators decided Friday. The decision is significant because HVDC lines can help ship wind power from the Midwest to demand centers in the East, reducing negative power prices and renewable curtailments.The US Federal Energy Regulatory Commission decided late Friday that MISO can add a set of connection procedures for MHVDC projects (ER18-1410) and add injection rights for these projects. Injection rights outline MISO's ability to receive energy from a line, and the project owner can dole out the injection rights to upstream generating facilities for conversion into interconnection service.
