[en] Real cooperation of Baltic States in energy sector is lagging behind our common political goals and our numerous declarations. What we have today in the three Baltic states as really useful common installations like common electricity grid, Dispatch Centre in Latvia, were mostly inherited from the Soviet times. Exchange of produced electricity from hydro power plants on the Daugava and Ignalina Nuclear Power Plant during different seasons of the year can be put as a very good example of mutual benefit for the two neighbouring countries and there are more similar examples

[en] West Kootenay Power Ltd is an electrical utility , serving 134,000 direct and indirect customers in the southern interior of British Columbia. The utility's asset include four hydro-electric generating plants on the Kootenay River with an installed capacity of 205 MW, and more than 6,500 kms of transmission and distribution power lines. At the end of the 1999 fiscal year the utility had assets worth $ 299 million, 1999 consolidated revenues of $ 130 million, and net earnings of $ 12.0 million. In accordance with the Utility's 20-year Transmission and Distribution Plan developed over the past several years and approved by the British Columbia Utilities Commission (BCUC) in 1998, no fewer than 25 projects valued in excess of $ 200 million will be spent between 1999 and 2004 on improving the transmission and distribution network, while rebuilding of West Kootenay Power's aging generating facilities will require a planned expenditure of about $ 100 million during the same period. Four transmission lines and generating substations were rebuilt during 1999. Over the next five years the Kootenay River Power Plants, among the lowest cost electricity producers in North America, will be fully rebuilt from water to wire, extending production by some 30 to 40 years. Major improvements have also began on the operation of the transmission system in anticipation of electricity market reform in British Columbia and adjacent jurisdictions. Significant strides have been made in addressing regulatory affairs and to continue the Utility's pioneering efforts in performance based regulation, focusing on operational improvements and innovation. Further details on operations and financial performance are provided within the annual report, inclusive of plans for 2000, which include further progress in the provision of green power, assumption of the management and operation of the Kelowna distribution system for a five-year term and participation in the Regional Transmission Organization as the province is gradually moving towards electricity market reform. The report also includes a 10-year summary of operational and financial results

[en] This article focuses on the outsourcing of water treatment by the British Nuclear Fuels Ltd.'s (BNFL) Bradwell-on-Sea nuclear power plant to Ecolochem to avoid the large initial investment cost and reduce maintenance costs. Details are given of the design of a cascade system to produce demineralized water for nuclear cooling by Ecolochem who own, operate and maintain the water treatment plant. (UK)

[en] The paper presents an algorithm for the calculation, in the frequency domain, of the induced voltages and currents on a generic metallic pipe network exposed to the electromagnetic interference from a power line or an electrified railway line. By assuming as known the voltages and the currents on the inducing line, the algorithm may be subdivided into the following main steps: a) determination of the ideal electromotive force and current generators to be applied to the induced structure in order to represent the electromagnetic influence from the inducing line; b) modelling of the pipe network by means of a suitable equivalent electric network; c) calculation of voltages and currents on the induced network

[en] A review of how the proposed electricity market in Ontario will price power once open competition begins in the year 2000 is presented. The importance for businesses to understand the patterns of their power consumption is emphasized, and the value of this knowledge is assessed. The paper also explored the role of historical energy use data, and consumption patterns, and provided some useful hints for gathering and organizing consumption data and forecasting . The importance of real time data, and of understanding how and why consumption patterns may affect the cost of power are also reviewed. 3 tabs

[en] This report describes the application of short-term models for production planning in analyses of large power systems. More powerful computers and more efficient algorithms make it possible to use detailed models in the analysis of the Norwegian electricity production system. Problems concerning short-term adjustment of supply and demand can be more efficiently dealt with. This type of model is suitable for studying availability of electric power as a function of time and price, modelling of exchange agreements, placement of reserve energy and as part of a hydro-thermal model. New functionality makes it possible to model constraints on the supply of fuel for thermal power stations and the requirements on both gradient and volume on exchange to the market. Requirements on gas deliveries affect, for instance, the marginal price in thermal systems. The possibility of adding a gradient constraint on exchange means that the interaction between Norway and the Continent can be better modelled. The biggest problem with using such a model for systems analyses is that the detailed modelling requires similarly detailed input data

[en] The application of the Ontario Hydro Networks Company (OHNC) to the Ontario Energy Board to seek approval for cost allocation and rate design methodology to recover revenue requirements for the provision of transmission services in Ontario are summarized. Insights that led to the arguments made in support of the application are also described. The paper contains an overview of plans for the operation of the transmission system, the agreement between Ontario Hydro Services Company (OHSC) and the Independent Market Operator (IMO), the stakeholder consultation process by OHNC to develop the transmission cost allocation and rate design methodology, a discussion of the major rate design issues, a summary of stakeholder opinions and a summary of OHNC's final proposal for transmission pricing. Public hearings on the OHNC application were held between February 16 and March 20, 2000. Final decision by the OEB is expected sometime in May 2000

[en] The use of microturbines for power distribution was discussed and illustrated by a series of overhead viewgraphs which accompanied this presentation. The paper presented an explanation of how microturbines work and how they can be used for onsite distributed generation. Microturbines were described as being portable and compact gas turbines of less than 100 kW, with high speed single shaft design. One of their main advantages are their capability for remote monitoring and operation. Results of microturbine testing at Suncor's Joffre Plant were presented. Some of the advantages of using Mercury Electric's IPP and TurboGenerator Distributor were also discussed. The operating modes for the unit include: (1) peak shaving for larger load customers, (2) cogeneration for base load applications, (3) emergency/standby/UPS applications, and (4) portable generation for temporary power. The unit can be used in commercial and industrial buildings and is also ideal for remote locations. The environmental benefits associated with the unit is that it can be used for cogeneration power and can utilize waste gas flares which have been associated with harmful emissions to the atmosphere. 7 figs
