PRESENT STATE OF GEOTHERMAL EXPLORATION AND
DEVELOPMENT IN MALAWI
  • PRESENTED
  • BY
  • JOSHUA JOSEPH CHISAMBI

INTRODUCTION
  • Malawi lies in south-eastern Africa between
    latitudes 9o S and 17o S and longitudes 32o E and
    36o E.
  • The country lies at the southern end of the
    Western branch of the East African Rift System.

  • The geology of the country is mainly comprised of
    metamorphics of Precambrian to Lower Palaeozoic
    age.
  • Volcanism associated with the rifting is well
    developed to the south of the country.

5
CURRENT OUTLOOK OF MALAWI'S HYDRO-ELECTRICITY
  • Hydroelectricity is the single largest source of
    power in the country contributing to almost 99
    of the country's electricity
  • This is generated on the Shire River, Lake
    Malawi's outlet and the largest river in the
    country

6
  • With installation capacity of 285 MW
  • But current generation is at 275MW
  • Sometimes it riches as lower as 175MW
  • While the base electricity demand is at 347MW
  • A lot of blackouts.

7
  • These problems have negatively affected the
    industrial sector
  • This has forced the government to consider
    alternative sources of power such as geothermal
    energy

8
GEOTHERMAL DEVELOPMENT STAGE IN MALAWI 
  • Malawi is at reconnaissance stage of geothermal
    exploration.
  • Our main objective is to identify promising
    areas and to rank them for detailed surface
    exploration.
  • Currently we have identified over 20 geothermal
    prospect areas and we would like to perform
    detailed investigations including drilling.

CHALLENGES MALAWI FACING TO DEVELOP GEOTHERMAL
ENERGY
  • inadequate skilled manpower and equipment for
    geothermal exploration and development
  • Inadequate policy and regulatory framework to
    attract private developers.
  • large upfront cost of geothermal resource
    exploration and development.
