As June approaches, some TOs will submit formula rate filings for rate year June 2026 - May 2027. Please remember to add your June 2026 - May 2027 Formula Rate Data into TC Planner by May 15, 2026. This is critical for TC Planner to function well. Application background, action items and available resources are provided below:

Background:

On April 11, 2024 at 3 p.m. EPT PJM launched a new tool, TC Planner tool. Transmission Cost Planner (TC Planner) replaced the previous Transmission Cost Information Center (TCIC). It helps PJM stakeholders in understanding current transmission costs and estimating future transmission costs.

Actions Requested:

1. Access Request: To add formula rate data into TC Planner for your company, write access is needed.

- An existing account in the PJM Account Manager will automatically grant users read-only access to the TC Planner. No additional access requests are required beyond having a valid Account Manager account.
