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
