Generation Adequacy and Investment Incentives in Britain: from the Pool to NETA

Three years after the controversial change of the British market design from compulsory Pool with capacity payments to decentralised energy-only New Electricity Trading Arrangements (NETA) market framework, we compare the two designs in terms of investment incentives. We review the biases of the Pool capacity payments design, the drought of investment following the introduction of NETA, and the reaction of the market during the first “stress-test” of NETA during the winter 2003. In an energy-only market such as NETA, it is essential that price signals are right and the system operator has a crucial role in contracting ahead for reserve. We recommend that NETA adopt a single marginal imbalance price as dual imbalance pricing distorts price signals in times of scarcity. The lack of long-term contracting that causes hedging and financing difficulties for power projects can becompensated by vertical and horizontal reintegration at a cost of increased market power

The Environmental Responsibility of the Regionalizing Electric Utility Industry

In this Article, I will address environmental issues in the context of our rapidly evolving understanding of restructuring. The market for electricity is fast becoming a series of regional marketplaces for wholesale transactions, operating on bid-based systems that move power at the lowest cost. There are plenty of states where power is still delivered as it has been for decades: by bundled service provided by vertically integrated utilities. However, the trend is toward regionalization, where independent entities control the transmission grid and play a major role in determining how power is delivered. These market participants, confusingly, have been known by a number of names and acronyms, though the most recent one is regional transmission organizations ( RTOs ). The trend toward regiona

Merchant Transmission Investment

We examine the performance attributes of a merchant transmission investment framework that relies on �market driven� transmission investment to provide the infrastructure to support competitive wholesale markets for electricity. Under a stringent set of assumptions, the merchant investment model appears to solve the natural monopoly problem and the associated need for regulating transmission companies traditionally associated with electric transmission networks. We expand the model to incorporate imperfection in wholesale electricity markets, lumpiness in transmission investment opportunities, stochastic attributes of transmission networks and associated property rights definition issues, the effects of the behaviour system operators and transmission owners on transmission capacity and reliability, co-ordination and bargaining considerations, forward contract, commitment and asset specificity issues. This significantly undermines the attractive properties of the merchant investment model. Relying primarily on a market driven investment framework to govern investment is likely to lead to inefficient investment decisions and undermine the performance of competitive markets
