Victoria Dam (Sri Lanka)
The Ceylon Electricity Board
Traditionally, power sectors across the Asia region were monopolies which were generally state-owned. During the last decade this situation has changed significantly, and power sectors are being restructured and reformed in order to create competition, attract private investment, and improve operational efficiency. Sri Lanka is no exception, where they have identified a need to develop a policy package in keeping with the current trends.

Cost of electricity is a key element in attracting foreign investment into the country for its economic development. Further, electricity has a direct bearing on the competitiveness of local industry in international markets. Therefore, the power prices should be comparable and have a competitive edge in relation to prices elsewhere in the region including South Asia and South East Asia.

The Ceylon Electricity Board use SYSIM from PWSC for simulating and optimising operation of the integrated Sri Lankan hydro-thermal power generation and irrigation supply system to help achieve this goal.

With a power generation installed capacity of some 79 GW, larger than the UK, Brazil is one of the largest electricity markets in the world. It is by far the largest in South America, with the Brazilian total primary energy consumption being twice as large as the aggregated figures for Argentina, Bolivia, Chile, Paraguay and Uruguay. There are approximately 50 million customers and total consumption has increased from 70 to 300 TWh in the last 20 years. Currently, some 95% of the Brazilian households have access to electricity.

During 2001 Brazil experienced a major electricity supply crisis triggered by a severe drought. The hydroelectric power plants that had generated 90% of Brazil’s electricity supply were left with dry reservoirs. However, the Government’s rationing programme successfully minimised the social and economic impact of the crisis. Since then, rainy seasons have been plentiful and the reservoirs returned to comfortable levels.

The new Government inaugurated in January 2003 is proceeding with the re-evaluation of the power sector policies initiated by the last administration after the 2001 crisis. The target is to solve regulatory bottlenecks, and overcome investment problems in the sector. As part of all this, PWSC's has been working in association with PriceWaterhouseCoopers to develop simulation and optimisation models of the countries combined power & water systems to support development of future policy and practice.


River Dee, Wales

The River Dee is a 70 mile (110 km) long river, which rises in the hills above Llanuwchilyn in Merioneth (Gwynedd) Wales, then passes through Bala Lake, over the man-made Horseshoe Falls and through Llangollen. East of Llangollen, Thomas Telford's Pontcysyllte Aqueduct, of 1805, carries the Shropshire Union Canal 120 feet overhead. At Farndon the river crosses into England and then passes through Chester. Below Chester, the river flows along an artificial channel, excavated when Sealand and Shotton were reclaimed from the estuary. This 'canalised' section runs in a straight line for five miles and passes beneath two road bridges at Queensferry. The first is a modern fixed cable-stayed bridge, the second, the Queen Victoria Jubilee Bridge, is of the rolling bascule type. A mile further on is the Hawarden railway bridge, originally constructed as a swing bridge but now never opened, carries the Chester - Wrexham line over the river. The name derives from the Celtic name for the river (Afon Dyfrdwy).

United Utilities and the Environment Agency use MOSPA from PWSC for simulating operation of the River Dee system.
