International Experiences of Nodal Pricing Implementation

This research paper by the Climate Policy Initiative examines the implementation of nodal pricing in power markets, primarily drawing on experiences from US Independent System Operators (ISOs) and the Iberian power market. It addresses the costs of transition, mechanisms for hedging locational price differences, the role of ISOs in system security, and the integration of variable renewables like wind and hydro power.

• US Independent System Operators (ISOs) that transitioned to nodal pricing typically recovered their one-time implementation costs within a single year of operation. These costs primarily consist of personnel training and specialized IT hardware and software, while benefits include improved grid reliability, better congestion management, and increased retail competition.
• To manage the financial risks associated with locational price differences, nodal pricing systems utilize Financial Transmission Rights (FTRs), which provide compensation for congestion and loss rents. To further enhance liquidity, some US markets use Auction Revenue Rights (ARRs), which offer longer-term hedging options, sometimes extending up to 30 years for transmission expansion.
• Nodal pricing does not necessarily undermine forward market liquidity; in the US, liquid trading hubs have emerged based on stable average prices across nodes. For example, PJM's Western Hub is described as likely being the most liquid forward electricity market globally, with significant proportions of energy-to-serve load contracted one to three years in advance.
• To protect retail customers from high price volatility caused by nodal calculations, many regimes aggregate nodal prices into regional averages. While generation and large loads face specific nodal prices, retail customers are often charged a regional average, though the granularity can be increased if customers become more price-responsive.
• The Iberian power market manages high wind penetration through a combination of integrated forecasting and a liquid intraday market with six sessions. This allows for flexible response adjustments up to three hours before dispatch, keeping demand for balancing services constant despite increased wind deployment.
• The document argues that the US ISO model provides a more transparent framework for information sharing and system security than the European TSO model. In the US, ISOs act as not-for-profit entities that separate the natural monopoly of market operation from commercial trading, whereas European power exchanges often hold monopoly positions.
