Grid tariffs are the main source of income for distribution system operators (DSOs). Reductions of tariffs increase the cost pressure on DSOs; assuming they work efficiently tariff reductions potentially lead to a decrease of the electricity system's quality if no reliability of supply criteria are incorporated in the regulatory system. Our statistically analysis shows that the correlation betw...

Micro CHP, installed in individual homes, will in time remove a substantial electricity demand on a dynamic basis at the low voltage level, and may, in some instances, neutralise or even reverse the power flows in distribution transformers. This will clearly have economic consequences for the Distribution Network Operator (DNO) in terms of lost revenue, but will also have profound consequences ...

1 This paper benefited from discussions with Dr. Ignacio PerezArriega of the Spanish Electricity Regulatory Commission who organized a workshop on the subject of capacity payment that motivated this work and from the presentations of Larry Ruff and Harry Singh at that workshop. The positions expressed in this paper,however, are the author's own views. 2 Department of IEOR, University of Califor...

In recent years, coal price has risen rapidly, which has also brought a sharp increase in the expenditures of thermal power plants in China. Meantime, the power production price and power retail price have not been adjusted accordingly and a large number of thermal power plants have incurred losses. The power industry is a key industry in the national economy. As such, a thorough analysis and e...

This work describes a framework that is being used to fulfil one of the main objectives of the ESPRIT project ELEKTRA : the discovery of the generalised patterns of change management for re-using them in similar settings in other electric supply companies. The term ‘pattern’ refers to such knowledge that may be repeatable from one situation to another, and shareable by many different users. Thi...

The reliability standards for electricity supply in a developing country, like Nigeria, have to be determined on past engineering principles and practice. Because of the high demand of electrical power due to rapid development, industrialization and rural electrification; the economic, social and political climate in which the electric power supply industry now operates should be critically vie...

Incorporation of radio controller units into heavy equipment used in the electricity industry provides numerous advantages including: improved electrical isolation between plant and operator, ability to incorporate an additional remote operator, and reductions in vehicle wiring and hydraulic hoses for equipment control. However, secure operation of vehicles and plant incorporating radio control...

This paper documents the approach used to update the U.S. geothermal supply curve. The geothermal supply curve analysis undertaken in this study estimates the supply of electricity generation potential from geothermal resources in the United States and the levelized cost of electricity (LCOE), capital costs, and operating and maintenance costs associated with developing these geothermal resourc...

As the vital link between sellers and buyers, transmission has long been a focus of academia and industry. With the unveiled power systems deregulation, the changing structure of the electricity supply industry and the emergence of independent power producers and independent customers are bringing transmission pricing into a new focus. Past capital investment must be recognized and future expan...
