[en] In this paper we discuss some of the special features of electricity that should be taken into account when assessing investment incentives, giving special emphasis to the role played by firms strategic behaviour. Furthermore, we assess the potential for some regulatory instruments to induce firms to undertake the efficient investments in the marketplace. In particular, some of the questions that this paper discusses are the following: Is the market alone the best mechanism to induce the right investment levels? How does the public good nature of security of supply interact with the provision of generation capacity? Are there regulatory measures to improve investment choices, reducing both the risk of blackouts as well as inefficient over investment?. (Author). 12 refs

[en] Prospects for the development of small and medium power reactors were reviewed at a symposium attended by more than 150 participants from 35 countries and five international organizations, held in Oslo in mid-October. Discussion centred on the current technical and economic status of reactors having an output of more than about 500 MWe, which might find application in the comparatively small electricity supply grids which are generally associated with areas where industrialization is not very far advanced.

[en] With the acceleration adjustment of China’s energy structure, the development of nuclear power plants in China has been going back to the fast track. While as the trend of slowing electric power demand is now unmistakable, it enforces the power system to face much greater pressure in some coastal zones where the nuclear power plants are of a comparative big proportion, such as Fujian province and Liaoning province. In this paper, the capability of load following of nuclear power plants of some developed countries with high proportion of nuclear power generation such as France, US and Japan are analysed, also from the aspects including the safety, the economy and their practical operation experience is studied. The feasibility of nuclear power plants to participate in the peak regulation of system is also studied and summarized. The results of this paper could be of good reference value for the China’s nuclear power plants to participate in system load following, and also of great significance for the development of the nuclear power plants in China.
