ERCOT’s Board of Directors has approved staff’s proposed 765-kV Eastern Backbone project and its $9.4 billion capital cost price tag, making it the most expensive project in the grid operator’s history.

The SPP board has approved the RTO's 2025 Integrated Transmission Plan that includes four 765-kV projects.

At a time when MISO’s long-term planning is under fire, the Organization of MISO States’ annual meeting featured speakers who vouched for the power of planning.

SPP stakeholders have endorsed the RTO's 10-year transmission plan and some of its proposed 765-kV lines, trimming about $2.5 billion in costs from the portfolio.

SPP staff have reiterated their position to defer part of the RTO's planned 765-kV transmission overlay, setting aside about $7 billion in regional projects from its 2025 transmission assessment.

SPP says accelerating load projections will result in a 2025 transmission plan that dwarfs the previous year’s record $7.65 billion portfolio — so much so that it is considering deferring some projects until 2026.

SPP’s Board of Directors has approved a pair of contentious measures that were put aside during its August quarterly meeting, a tariff change to integrate and operate high-impact large loads and a revised cost estimate for a 765-kV transmission project.

SPP and its members are working together on a draft 765-kV transmission overlay as part of its 2025 Integrated Transmission Planning assessment that will dwarf 2024's record study.

SPP’s Board of Directors agreed to defer action on a 765-kV transmission project with a ballooning cost estimate and staff’s large load integration policy, both the source of much stakeholder discussion.
