Malawi Mini Grids
Field and aerial
investigation
Malawi Mini Grids(Background)
• Project: Malawi Rural Electrification Public-Private Partnership (RE PPP): Mini Grids
• Client: Millennium Challenge Corporation (MCC)/Millennium Challenge Account –Malawi (MCA-M) – USA/Malawi
• Phase 1 of 2 phases
• Key tasks: To identify, evaluate and prove viability of three mini grids to be developed
in the rural Malawi
Malawi Mini Grids(Programme)
• Field investigation and
sites selection - done
• Reporting to other
teams – going on
• Aerial photography (?)
• EIA - starting
• Sites geological and
detail ground surveys
• Preliminary design

Team Project Progress:
• Malawi , Lilongwe – April 20
to April 23, 2010 – Meetings
with MCC/MCA-M and other
Malawi Government institutions
and departments: Phase 1 & 2
concepts
• Malawi, Northern Region – May 17 to June 01, 2010 – Field and
Aerial Investigation and Mini Grid Sites Selection
Malawi Mini Grids(selected sites)
1. Lufira existing
irrigation and water
supply scheme
2. Jalawe dam site and
hydropower plant
3. Bale hydropower
generation site
4. Chisanga Falls hydro
generation site
Lufira River Irrigation and Water
Supply Scheme
• LUFIRA RIVER existing irrigation and water supply scheme – no electricity available
• Northern Region of Malawi, Karonga District
• Latitude:09o48.169’S Longitude:33o47.761’E
• Planned development: intake structure on upper reaches of Lufira River, some 2,5 km of pipeline, small scale hydroelectricity plant situated in vicinity of existing irrigation off-take weir

Jalawe Dam and Hydro Plant
• JALAWE DAM and HYDRO PLANT situated on
North Rukuru River some 2 km off M26 road
• Northern Region of Malawi, Karonga District
• Latitude:09o57.464’S Longitude:33o45.413’E
• Planned development: medium size dam and
storage impoundment feeding the small scale hydroelectricity plant situated at the dam site,
access road, transmission line and auxiliary equipment

Environmental/Social Impact Assessment
• General overview of study area
• Purpose and framework of EIA
• Regulatory issues in Malawi
• Environmental issues associated with proposed mini grids development (solar, hydro, wind, etc)
• Site specific issues due to hydro development
• EIA issues associated with project activities
• Recommendations/remedial issues
