PJM-style Locational Marginal Pricing

A centrally optimised nodal market in which wholesale prices reflect marginal energy cost, transmission congestion and losses, supplemented by capacity and ancillary-service markets.

Critiques

Open questions, objections and unresolved design issues.

Critiques

Key questions include:

  1. How computationally and institutionally complex should central optimisation become?
  2. How should nodal-price volatility be hedged?
  3. Does nodal pricing provide a sufficient investment signal without additional capacity mechanisms?
  4. How should distribution networks and DER be integrated?
  5. Is interval-based reoptimisation responsive enough for increasingly continuous cyber-physical processes?
  6. Does marginal pricing provide the desired conception of fairness?
  7. Does treating users at the same node identically ignore differences in service history or system value?

LMP is best understood as a powerful transmission-level coordination architecture, not automatically a complete end-to-end electricity-system design.
