Electrical market

In restructured electric markets, the vertical electric monopoly vill no longer be the sole provider of electricity. The generation, transmission, distribution, and customer service functions will be separated. The upstream generation function will be competitive, allowing new, any power producer to produce and sell electricityin any service territoi"y. The transmission and distribution functions will continue to be regulated, but will be required to allow access to power suppliers and marketers. This separation or unbundling of the industi"y is necessai"y to provide nondiscrimina-tory access for all suppliers of electricity. Customers will have their choice of electric suppliers. 

In these restructured electric markets, prices will be determined more by market forces and less by regulatory proceedings. To some, introducing competition will promote more efficient markets, providing the proper financial incentives for firms to enter or leave the industiy. In this way, consumers will benefit from lower production costs and, hcncc, reduced electricity prices. To others, restructuring will increase electricity prices for some customers, sacrifice the current environmental and social benefits, and jeopardize system reliability of the status quo. 

Wlieli initially adopted, TOU rates were based on projections of future costs by season, month, day, or hour. However, advances in metering and communications technology now afford utilities the ability to transmit prices to customers based on actual operating costs and to read meters in real time. This realtime TOU pricing is one of the most important aspects of many of the restructuring efforts to date. They can provide customers with direct access to the prices arising in competitive electric markets. 

As the size of markets have increased and the optimal size of electricity generation units have decreased more electricity markets are being privatized and restructured to allow more competition into the markets and less government control over pricing. 

Today s situation is virtually the reverse. No new nuclear power plants are under construction in countries that have a competitive electricity market Also, because of World Bank and other lenders reluctance to assist construction of nuclear plant, there are questions how many of the 25 or so reactors, now under construction, will be completed. In countries where public opinion matters, people perceive the risks, but see few benefits, whilst the electricity industry and governments, with a few exceptions, such as France and S. Korea, are too concerned about the vociferous opposition to this power source to do anything, but sit on... 

Nuclear plants operate in 17 of the 24 states that have opened their electricity markets. The nuclear facilities in those 17 states account for 60 of the 103 operating reactors in the United States.

The situation may be illustrated well by the development of the public discourse on hydropower in Switzerland over the past few years. As 60% of Swiss electricity generation stems from hydropower, its environmental impacts have time and again raised political debates over the past 50 years. More recently, the liberalization of electricity markets has opened up new windows of opportunity for the development of new approaches of mitigation. One example of an integrative concept was developed by an interdisciplinary team of researchers in the late 1990s. It has been implemented in the currently operating eco-label for sustainably produced electricity in Switzerland (naturemade star). 

After the law passed, the political debate about the sustainable management of hydropower came to a standstill. The law could only be applied in the context of a renewal of the water use licenses. In Switzerland these licenses typically run over 80 years and therefore no major changes in operation could be expected before the year 2020. Furthermore, the deregulation of electricity markets begun to shape expectations in Switzerland. This new market order put pressure on hydropower operators to reduce cost and to act as competitive firms. Environmental requirements were considered as a direct threat to economic survival of the plants. 

Nevertheless, the new market order also opened up opportunities for utilities to deal with environmental problems. Experience from other countries with deregulated electricity markets showed that consumers are willing to pay extra for electricity with low environmental impact. A number of incumbent electric utilities, as well as newly emerging green power marketers, began developing green power products to differentiate themselves from other suppliers [11].

To illustrate the impact of new entrant allocation, we calculate the long-term investment equilibrium for a competitive electricity market. Section 3.3 will subsequently assess the impact in real electricity markets, where existing generation assets do affect the generation and price structure. 

According to the latest observations on the EU electricity market and to the emerging windfall profits debate in the EU, we assume that power generators have the ability to pass on to electricity customers 100% of their extended cost rise. For the sake of convenience, this rise in a given country equals the C02 price multiplied by the national unitary emission of the power sector, whatever the allocation method for the cement industry may be - as if the allowances in the electricity sector were always grandfathered. 

The ideal trade-off between ensuring a competitive auction with low transactions costs and providing steady liquidity is difficult to judge before we have gained more experience with allowance auctions. If auctions were to be based on experience with electricity markets, then a frequent uniform price auction (e.g. weekly), would allow small participants to directly acquire the allowances they need to cover their emissions in the auction.34 High frequency would ensure that bidders pay a price close to the price on the secondary market at the time of emission, thus limiting risk exposure. In electricity markets this approach has been successfully implemented with low transaction costs (various pool type market designs).
