Scottish Water seeks construction of small hydro plants

State-owned water utility Scottish Water invites expressions of interest from firms to design, build, equip, operate, and maintain small hydroelectric projects throughout Scotland. Responses are due October 7.

Scotland’s first minister proposed legislation in September that would give Scottish Water new powers to build hydropower projects, wind farms, and “green” power stations in partnership and competition with established energy companies.

Scottish Water seeks expressions of interest from firms to participate in five-year framework agreements with a maximum of four companies to build small hydro projects for a total cost of 10 million pounds (US$15.6 million).

Scottish Water outlined separate lots for design, construction, and commissioning; supply of mechanical, electrical, and control equipment; and ongoing maintenance of about 30 mini-hydropower generating plants on Scottish Water sites. However, it said agreements could combine the tasks within the framework agreements.

Most plants are to be less than 100 kW, with some of capacities up to 500 kW. A range of different turbines are to be used.

Firms submitting expressions of interest will be asked to complete a pre-qualification questionnaire from which a short-list of about seven firms will be invited to proceed to the next stage of the tender process.

Expressions of interest are due by 2 p.m. October 7 by e-mail to For information, contact Steven Carvel, Commercial Contract Manager, Scottish Water, Watermark, Alba Centre, Alba Campus, West Lothian, EH54 7HH Livingston, United Kingdom; (44) 1506678703; Fax: (44) 1506678624; E-mail:; Internet:
