Reliability Must-Run Contracts: Keeping Old Plants Alive for Grid Support

Why keep an uneconomic plant online? Reliability must-run contracts provide local voltage support while transmission upgrades or new resources are developed.

What Causes Grid Congestion: Physical Limits and Market Signals

What causes grid congestion? Thermal, voltage and stability limits can trigger redispatch, curtailment and price spreads between locations.
Renewable Curtailment: A Sign of Market Failure or a Rational Operational Choice? — wind turbines and high voltage transmission towers across a remote grassland landscape

Renewable Curtailment: A Sign of Market Failure or a Rational Operational Choice?

When is renewable energy curtailment a grid constraint, and when is it an efficient market signal? Compare congestion, oversupply and storage responses.
