National Grid Electricity System Operator (ESO) and Ofgem have launched reviews of Locational Marginal Pricing (LMP) as a potential basis for GB market reform. This focus on LMP has been prompted by the rise in balancing mechanism costs and a belief that constraint costs will continue to escalate in a high renewable energy, net zero scenario. A parallel Review of Electricity Market Arrangements (REMA) being carried out by the Department for Business, Energy and Industrial Strategy (BEIS) also plans to consider LMP, but is taking a broader view of potential market reform to deliver net zero electricity by 2035, ranging from radical change to a more incremental modification to existing arrangements.
This insight paper looks at existing LMP markets in the US to better understand: LMP working in practice; the impact that this type of market design may have on both low carbon generation and strategic network investment; and whether there are lessons that can be learned and applied to the reform of the GB market.
