Hydro Power

Hydro Power in Kenya

  • Kenya hydropower sector has been playing a key role in meeting energy demand as a renewable source of energy.
  • Since 1990s, hydropower has dominated over 70% of the total installed generation capacity and 80% of the total electricity generation.
  • However the sector has not been without challenges especially related to natural causes like drought.
  • The theoretical hydropower potential of Kenya is estimated at 6000 MW installed capacity or 30,000 GWh/year, while the technical potential is estimated at only 9,000 Gwh/year (2100 MW).
  • Small hydro potential is estimated at 3,000MW of which it is estimated that less than 30MW have been exploited and only 15MW supply the grid.
  • By June 2016 the total installed large hydropower capacity was 820 MW.

 

Number of installed MegaWatts

The Government is carrying out phased feasibility studies to establish the capacities of potential hydro power sites across the country. The Least Cost Power Development Plan has identified a number of sites where hydro power could be developed effectively.

Planned large hydropower schemes

Electricity generation by hydropower power is strongly affected by the prevailing hydrology. However, the advantage that they provide power at low operating costs. Large schemes with storage facilities are able to react very fast to variations in electricity demand caused by short ramp-up times and are thus very valuable for the provision of peak load capacity at low costs. In the long-term, there are several plans of developing large hydrological schemes, the majority of the projects are planned to be constructed as multipurpose scheme

Small Hydro Power Plants

  • In 2016, the small hydro plants contributed 14.5 MW to the national grid.
  • The energy policy of 2004 defines small hydropower (SHP) as run-of-river power plants with installed capacities below 10 MW.
  • These are further broken down into small, micro or pico hydropower.
  • It is estimated that at least 3,000 MW of potential SHP capacity exists in Kenya. However, only approximately 32 MW is currently installed, representing 5 per cent of the total installed hydropower capacity in the country.
  • Existing SHP plants have varying ownership structures including private, community or public ownership models.

Policy Framework

Feed in Tariff: The Feed in Tariff policy provides for stepped fixed tariffs for electrical energy supplied in bulk to the grid operator at the interconnection point.

The tariffs shall apply for 20 years from the date of the first commissioning of the small hydro power plant. The small hydros 0.5 MW is offered a tarrif of 0.105 US $ /kWh and 0.0825 US $ /kWh for 10 MW. This tariff also applies for projects with great than 10 MW and maximum cumulative capacity of 100MW.

Standards

All hydro power plant are requires to meet the standards stipulated by Kenya Bureau of Standards.  Some standards that relate electrical distribution and transmission of hydropower include;

KS 1878-1:2010: Electrical power transmission and distribution – Guidelines for the provision of electrical distribution networks in residential areas – Part 1: Planning and design of distribution systems.
KS 1859-3:2010: Electrical power transmission and distribution- High-voltage operating regulations – Part 3: Model regulations-Recommended model regulations relating to power systems for operating, access control and

KEBS and Stakeholders are developing Small hydro standards for Kenya.

Studies

  • Small hydro Scoping Study Kenya : The objective of this scoping report is to provide the basis for understanding what the  potential for hydro power development is in the proximity of tea factories, the interest expressed by the tea companies, present electrical practices, potential for replication, potential for rural electrification, CO2 emission reduction and the existing know how and regulatory framework are for such projects to evolve.
  • Policy and regulatory framework conditions for small hydro power in Sub-Saharan Africa Discussion paper – June 2010: outlines the potential of Micro Hydro Power (MHP) and its current positioning in terms of existing and planned MHP projects in Sub-Saharan Africa. As a second step, the main barriers for MHP sector development are briefly described and wherever possible underlined with some examples from the field. For each main barrier, several potential and existing mitigating strategies are outlined and good practices are identified. The report concludes with some preliminary recommendations of how the gap between existing top-down regulation and regulatory needs of MHP projects can be overcome in order to deploy MHP in Sub-Saharan Africa on a larger scale.
  • Kenya National Hydropower Atlas: The objective of this project is to develop and established a national database and information retrieval system for the national hydropower development and undertake detailed feasibility studies for ten sites, which will have been selected using the instruments of the atlas.
