KenGen as a responsible business entity seeks to mainstream its environmental sustainability goals within all its operation areas as a part of its corporate strategy to enhance our core mandate of generating sustainable power for the nation. KenGen therefore continues to comply with applicable environmental laws and regulations.

KenGen’s Environmental sustainability involves making decisions and taking actions that are in the interest of protecting the natural world, with emphasis on preserving the capability of the environment to support human life. KenGen recognizes that its operations have impacts on the environmental, social and economic aspects at the national and global level and hence the need to mainstream environmental sustainability objectives in all its operations and activities.

KenGen’s Environment sustainability focuses on:-

  1. Social Safeguards
  2. Project appraisals & monitoring
  3. Climate change services
  4. Environment management
  5. Environment Sustainability

Social Safeguards

KenGen recognizes that social safeguard policies are essential tools to prevent and mitigate undue harm to people within our project areas. When identifying and designing a project, safeguards help us to assess the potential social risks and impacts (positive or negative) associated with a development intervention.

Implementation of Olkaria RAP land project is our flagship social safeguard project that is supported by World Bank.

Projects Appraisal & Monitoring Section

The section conducts preliminary ESIAs, appraisals and environmental and social monitoring for proposed project sites. These include the biodiversity studies for the proposed sites, project stakeholder management and Environmental sustainability reporting. The studies are carried out prior to the full ESIA studies. The studies are carried out to establish comprehensive baseline information on socio-economic status and on fauna and flora of the proposed project area and to determine the Terms of Reference to be used in the full ESIA studies. The section also undertakes post feasibility/ESIA appraisals.

Currently projects being undertaken by the section include:-

  1. Closure of Olkaria IV RAP activities
  2. Ngong Wind III - Currently the biodiversity studies are being undertaken
  3. Proposed Meru wind
  4. Prefeasibility studies for Proposed Marsabit Wind farm
  5. Prefeasibility studies for upgrading of Gogo Power Station.
  6. Update of feasibility studies for Raising of Masinga dam.

Implementation of Climate Change Mitigation Projects 

KenGen has revamped its Good to Great transformation strategy with focus on achieving environmentally sustainable development in discharging its mandate of generation of reliable, safe, quality and competitively priced electric energy in the Eastern Africa region.

To enhance sustainable development, KenGen has to date developed and registered six (6) Clean Development Mechanism projects (CDM) under the United Nations Framework Convention on Climate Change (UNFCCC). These projects are:-

  1. Olkaria II Geothermal Expansion
  2. Redevelopment of Tana Hydropower project
  3. Optimization of Kiambere Hydropower project
  4. Olkaria IV Unit 1 & 2
  5. Olkaria I Additional Unit 4 and 5
  6. Ngong Wind 5.1 MW

The annual estimated CER’s from KenGen’s registered projects are as indicated in the table below:-

ProjectMWEstimated tCO2 equiv/year
Olkaria II (Unit 3) 35 149,632.00
Tana 19.6 25,680.00
Kiambere 20+ 41,204.00
Ngong 5.1 9,941.0
Olkaria I, AU 4&5 140 635,049.00
Olkaria IV 140 651,349.00
Total 359.7 1,512,855.00


The CDM projects have resulted to environmental and social benefits to KenGen and communities around the projects through commitment of 10% of the CDM revenue to Community Benefits Programs from the World Bank’s Emission Purchase Agreement for the Olkaria II, Tana and Kiambere CDM projects.

CDM projects have contributed to benefits for KenGen’s stakeholders through Community Benefit Projects funded by part of the revenue from the CDM projects. An example of the beneficial projects is the Redevelopment of KenGen’s Tana Power Station that was registered as a Clean Development Mechanism (CDM) project in October 2011. KenGen, through an Emission Reductions Purchase Agreement (ERPA) with International Bank for Reconstruction and Development as Trustee of the Community Development Carbon Fund (CDCF) used part of its CDM revenue to implement the Community Benefit Projects.

Some of the Community Benefits Projects that have been implemented include Mirira and Kiambaa Primary Schools which are the beneficiaries of upgraded classrooms, landscaping, new desks, and a refurbished water tank; while the residents of Mirira now have a brand new footpath courtesy of the implementation of the CDM projects at Tana Power Station. It is through the plant’s recent redevelopment that additional renewable energy is annually generated, which resulted in the reduced use of fossil fuels, and consequently reduction of greenhouse gases [GHG] emissions.

Going forward, KenGen intends to enhance its portfolio of climate change mitigating projects by registering new climate change projects including the following:-

  1. Olkaria V
  2. Olkaria I additional unit 6
  3. Olkaria I rehabilitation

Environment conservation 

KenGen is committed to environmental conservation and sustainably safeguarding the environment it shares with other communities at its areas of operations - for today and generations to come. The company has invested in long-term programs dedicated to sustainable environmental conservation and promoting a tree planting culture within the organization.

Environment conservation involves sustainable management of ecological resources. KenGen strives to be a leading organization within the energy sector in limiting negative and, where possible, having positive direct and indirect impacts on biodiversity and natural ecosystems so that its practical performance in this area matches its conservation aspirations. KenGen recognizes the significance of ecological restoration and enhancement in areas where the company operates and derives its generation resources.

Since 1986 KenGen has been running three tree nurseries with a total annual output of 350,000 seedlings. These seedlings have over years been used in CSR activities and in protection and restoration of Tana and Mau catchment areas thus enhancing sustainability of KenGen hydropower generation.

The Schools’ Green Initiative Challenge (GIC) is a flagship environment program that is being implemented through KenGen Foundation. GIC is a unique project, implemented in partnership with Better Globe Forestry and Bamburi Cement Ltd. KenGen is also establishing tree buffer zone projects around the hydro dam in Eastern region with a purpose of reducing encroachment and effects of siltation and restoration of ecosystems in Ngong wind farm and in Olkaria Geothermal project area.
