Session 1 Assessing Low Head Hydro Availability
• The choice of method strongly influences the answer!
• Local data is best, but…
• hydrological expertise is required for better results

Session 2 Technologies
• Low heads roughly 2 to 35m
• Large range of turbine products available - (axial type and radial type)
• Often low speed turbines - (approx. 100 to 500 rpm)
• Low speed direct coupled generator > good but expensive
• Gear box can make a project feasible > reduction generator investment
• Fish friendly turbine concepts
• Risks - Power loss due to grass or algae
- Incorrect Design on the intake/drafttube side –
- High head loss

Where, and how suitable is the ‘Grid’?
• Tend to be in awkward locations
• Consider during initial feasibility
• Can be a go/no-go decision maker
Look at:
Distance
Voltage
Local Loads
Single / 3 Phase
Switchgear and Ratings
Accommodation

Session 4 Planning &
Public Acceptability
LDNPA
• support small scale and community based hydro schemes
• promote the use of renewable energy sources and new technologies that reduce carbon use
• are developing policy that promotes community-level solutions to reducing carbon emissions
• see hydro schemes as part of this future approach

Session 4 Planning &
Public Acceptability
What are appropriate strategies?
- Not ‘one size fits all’
- Staged & structured approach?
• scoping impacts/potential concerns
• key informants and interest groups (e.g. other river users)
• local publicity
• local meetings, consultation, participation
• community benefits
