First Geomagnetic Standard Update at PC

The first update on the Federal Energy Regulation Commission’s rule on geomagnetic disturbance events was one of several presentations at the Planning Committee at its March 9 meeting.

The FERC finalized the TPL-007-1 reliability standard on geomagnetic disturbance events last fall, accepting the two-stage process under which the North American Electric Reliability Corporation established the standard.

PJM has been working with stakeholders on the standard’s five-year implementation plan, including coordination and collection of the appropriate modelling data. The standard establishes establish requirements for transmission system planned performance during geomagnetic disturbance (GMD) events.

During a GMD event, geomagnetically induced currents may cause transformer hot-spot heating or damage, loss of reactive power sources or increased reactive power demand. Failing to plan for these events could result in poor transmission system performance, degradation to reliability, damage to equipment and potential interruption of customers.

PJM presented the latest on the Transmission Expansion Advisory Committee redesign with the rollout of the new Planning Community tool. Stakeholders may soon receive responses to questions submitted to via the tool, which the redesign group will introduce the tool at the Tech Change Forum March 21 and 22.

After several years of implementing the FERC’s Order 1000 on competitive bidding, PJM developed a new manual – Manual 14F: Competitive Planning Process, which it presented for a first read. The manual gives PJM a single source to detail the process and decision-making information regarding the implementation of the order. The majority of the manual’s content already in exists in PJM materials, just not in manual documentation. PJM will continue to solicit stakeholder input for the manual.

PJM presented the progress of the Designated Entity Design Standards Task Force. The task force looks at minimum engineering design standards (including geography, physical and local needs such as noise level and undergrounding requirements). The standards would apply to projects that are competitively solicited and would address transmission lines, substations and system protection, control design and coordination.

PJM also reviewed the winter season resource adequacy and capacity requirements issue charge and its three key work activities – winter peak load forecasting, winter season resource adequacy and winter season reliability requirements.

Other Committee Business

  • Update on the Generator Interconnection NOPR (Notice of Proposed Rulemaking)
  • Update from NERC and regional coordination
  • Updates to the ComEd Planning Criteria
  • A review of documentation for NERC MOD-032, which establishes consistent modeling data requirements and reporting procedures for development of planning horizon cases
  • Administrative update for Manual 14B: PJM Region Transmission Planning Process

After providing an overview on future Planning Committee meetings topics (such as methodology updates), PJM asked members to provide feedback for other topics for future PC consideration.
