Liberalization has improved the administrative efficiency of the electricity system, but what has been its impact on technical performance? Energy efficiency of the distribution system, its technical quality of supply and environmental performance are issues which where largely conspicuous in their absence in the debate, but maybe it is time to address them now. A discussion paper from Leonardo ENERGY.
Liberalization of electricity market scrutinised | Leonardo ENERGY - 0 views
-
Throughout the world, the deregulation of utilities like gas, railway, water and telephone is at the centre of many governments’ economic policy. The liberalisation process of electricity, however, is slower than anticipated. Both in Europe and North-America, for various reasons, a full-scale implementation of the liberalization of the market is being hindered. A lack of sufficient physical capacity to allow cross-border trade of electricity is only one of those reasons. In the long run, the prices of electricity can't be expected to go down. Or will they? A reflection based on the discussions at the World Forum on Energy Regulation, Rome, October 5-9, 2003.
White, green and black certificates: three interacting instruments | Leonardo ENERGY - 0 views
-
This paper presents three different types of certificates ('white' for energy savings, 'green' for renewable electricity, and 'black' for greenhouse gas reductions in the European Emission Trading Scheme). The current limited experiences with these instruments already allow to define some of the success factors for these new instruments. A synthesis of their current application presents how much energy is saved today due to these certificates, and how much green electricity is produced. A discussion on the methods for setting the targets, measuring the impacts on the market and the interaction between these different instruments concludes this paper, followed by a reminder of the proposal to create an international agency on global stewardship for climate change issues.
Distribution transformer efficiency in a liberalised market | Leonardo ENERGY - 0 views
-
A widespread use of high efficiency transformers could save the world 100 TWh/year. Under normal conditions, purchasing high efficiency transformers is both economically and environmentally sound. In the liberalized European energy market however, the regulatory and financial framework obstructs utility companies from making long term investments like purchasing high efficient transformers. National regulators put pressure on utility companies to do cost cutting and do not compensate with sufficient incentives for energy efficiency. According to this paper, there is a heterogeneous treatment between generation on renewable energy and transformer efficiency. Yet the greenest kWh is still the one that is saved, even when it is compared to a kWh derived from a renewable source.

Energy Saving by Reducing No Load Loss of Distribution Transformers | Leonardo ENERGY - 0 views
-
In Japan about 16 million units of distribution transformers are in service. These transformers are expending a huge amount of energy in the form of no load loss and load loss. Among these losses, no load loss is major. No load loss can be saved dramatically by changing these transformers to amorphous transformers (i.e., amorphous metal-based transformers). This paper estimates the scope of the possible energy saving and reduction of CO2 emissions by the adoption of amorphous transformers in Japan and in China.
