MEng Gp Proj 13 - Hampton Lucy Micro-hydro Scheme
Notes for Initial Meeting
Under the leadership of the Parish Clark, Mr Scaife, Hampton Lucy (Civil) Parish Council would like to investigate the possibility of generating "sustainable" electric power from the River Avon running next to the village. The School has "offered" the services of an MEng Group Project to evaluate the possibilities.
The Avon already supplies nearby hydro-power, since for some 200 years (perhaps much more) there has been a watermill close to the village. The mill is still operating (grinding maize flour for chapattis); the miller is Mr John Beddington who has been working the mill (two undershot water wheels) for about 20 years. The civil works for the watermill - main dam across the river, 300m leat, diversion channel etc may be partly available for the new project. However no significant (i.e. over say 6cm) drop in the water level at the watermill intake is tolerable.
Rough plan of potential site:
- Where is the best site for a hydro plant, taking into account flooding (and flood reduction), economics, the interest of the miler etc?
- At what flow and head should it be rated?
- Should it somehow connect directly to electricity users in the village or just to the local electricity distribution network?
- What will the plant cost and how can benefit:cost ratio (or internal rate of return) be maximised?
- How might the plant be financed, owned, and managed?
- Who are the stakeholders in this project and how can their interests be accommodated in the decision making?
- What statutory constraints apply?
- What should the detailed civil, mechanical, and electrical design be?
