Suppliers would be “disadvantaged” by National Grid Electricity System Operator’s (ESO’s) proposal for a Local Constraint Market, according to Energy UK. The trade association warns that ESO’s plan for an alternative price adjustment mechanism risks creating a price imbalance which will ultimately eat away at supplier profits. The ESO’s Local Constraint Market is designed to manage transmission constraints during peak wind energy flows by creating a local marketplace that diverts extra wind power into local assets at times when southward flows are at capacity.
