“…The Culligran site is located in a Scottish National Reserve where a 17 MW, 10 blades Deriaz turbine is coupled with a 2 MW Francis turbine [20]. Scottish and Southern Energy plc invested in an 18-month project to refurbish the 43 years old, Deriaz turbine in order to extend the plant's operating life by a predicted further 30 years' without further major refurbishment or significant capital expenditure and to maximize efficiency and output.…”

The growing importance of the efficiency and operational range of pumped hydro energy storage (PHES) installations, especially for variable load operations, calls for the use of more efficient turbomachinery designs. Deriaz turbomachines are promising candidates, since, among other advantages, they can operate as reversible pump-turbines with high hydraulic efficiency over a wide range of operational loads. Deriaz pump-turbines are largely absent from the literature and this paper gives an overview of their design, application and performance features. Particular attention is given to the hydraulic characteristics and design of a downsized model (6-21 kW) suitable for micro-scale PHES applications. This paper provides a practical and easily-built method to implement a micro Deriaz pump-turbine runner which gives a good outline for design at high yield (about 90%). The analysis is supported by extensive numerical simulations for different working conditions and validated by experimental data. The results confirm the superior characteristics of Deriaz pump-turbines and validate the design process, which is described here for the first time.

The second half of the 20th century saw over 60 large concrete dams built in Britain for a wide variety of water supply and hydroelectric reservoirs. However, with increasing social and environmental concerns about such projects, the Maentwrog gravity dam built 10 years ago could be the UK's last. The late Geoffrey Binnie described the development of concrete and masonry dams in the UK up to 1942, from Vyrnwy to Haweswater. This paper aims to complete that history. It describes the development of concrete dams, from simple mass-concrete gravity structures to prestressed and double-curvature arch designs, and the effect of improving technologies. It also looks at how the expertise of UK dam designers has been exported worldwide and concludes with a brief review of the World Commission on Dams report.
