From possibility to policy: Charting Kenya’s BESS journey

Kenya is no stranger to innovation in energy. With geothermal-rich Rift Valley, world-class wind corridors in Marsabit and a solar belt that stretches across vast regions, the nation has made bold strides in green energy. As it stands, the share of electricity generation capacity in Kenya is 92% renewable. As impressive as Kenya’s renewable portfolio may be, there’s a growing need to bridge the gap between resource abundance and energy demand.

Kenya is also suffering from grid instability, struggling to balance daily demand variations and an ageing transmission network with increased generation from wind and solar resources, which are intermittent in nature. Kenya has ambitions to get to 100% green generation by 2030, and will BESS be part of the solution is a big question the sector is facing…

Kenya is reaching a pivotal cross-road: to be proactive or reactive?

Kenya’s peak electricity demand hit 2.36GW in August 2025, with just 3GW in effective supply capacity (assuming the wind is blowing and the sun is shining!). With power outages on the rise and a freeze on new Power Purchase Agreements (PPAs) only just appearing to be lifted, the pressure to stabilize supply without reverting to expensive thermal generation is mounting.

Moreover, the surplus generation from geothermal (especially during off-peak hours) is often vented—literally released into the air—because the grid cannot absorb it. This not only wastes valuable renewable energy but also reduces the sustainability of geothermal wells.

The energy sector has been on a standstill since the 2021 PPA Taskforce was appointed by the government, however after much stakeholder deliberation ‘a lifting of the moratorium’ seems imminent. Meanwhile, development of power generation projects has fallen behind the country’s power planning cycle.

In addition, the priority has shifted to focus on developing baseload power in particular hydro and geothermal assets in order to rebalance the grid after years of developing wind and solar assets. Gas power is also under consideration. While baseload assets are desirable for grid stability and reduction in overall cost of power, they take years to develop and operationalize.

As such, there is a clear and present danger that the gap between demand and supply will continue to grow, leading to critical load shedding, as seen in other markets such as Zambia and South Africa. Any situation like this will constrain GDP growth and force C&I players to consider increased uptake of off-grid solutions, further weakening the underlying economic stability of the on-grid sector.

The proactive solution to mitigate a possible power crisis is to act quickly – and includes the acknowledgement of the role of Battery Energy Storage Systems (BESS) in augmenting the development of large-scale wind and solar assets. This is through the integration of BESS as either stand-alone units at key nodes in the grid or in a well-defined manner into new, low-cost assets – e.g. as part of quick-to-build solar and wind projects.

How BESS can help Kenya

BESS is not just a backup plan—it’s a strategic enabler:

  • Grid stability: Acts like a buffer, smoothing out the peaks and troughs of electricity demand and supply, reducing frequency and voltage issues which occur daily.
  • Reduce transmission loss: Kenya Power lost 24.2% of purchased power in H2 2024, above the 17.5% threshold recommended by EPRA, the country’s energy regulator. BESS can act as a ‘Virtual Power Line’ to help reduce such losses.
  • Economic efficiency: Reduces the need for high cost fossil-fuel backups and diesel generators.
  • Renewable maximization: Stores excess renewable energy and releases it when most needed, decreasing the need for Time of Use tariffs and for ‘venting’ geothermal assets.
  • Industrial competitiveness: Lowers electricity costs, enabling more affordable manufacturing and business operations.

With the upcoming Eastern Africa Power Pool (EAPP) opening up regional energy trade and the 2024 Energy Regulations enabling market participation, Kenya has a further potential benefit of BESS adoption – providing ancillary services and trading capabilities on a wholesale market. A differentiator from neighboring countries that currently have significant excess supply from large-scale Hydros.

Challenges to consider

However, transitioning to BESS won’t be plug-and-play. There are critical hurdles to overcome:

  • Tariff structures: Kenya’s current electricity pricing models are not optimized for storage. There is a need for cost-reflective tariffs if IPPs are being asked to incorporate BESS into new-build assets, or there is a need for appropriate incentivization for BESS developers to participate in ancillary service markets.
  • High capital costs: While battery costs are falling, upfront investment remains substantial, especially when revenue mechanisms are undefined.
  • Fast-paced innovation: BESS technology has already been proven with countries such as the UK showing global leadership at grid scale. The UK has limited interconnection capacity and heavy reliance on wind energy, with a resulting rapid increase in BESS adoption to stabilize its electricity system and increase energy security.
  • Grid integration: Without careful planning, any BESS will be inefficient. Placing these systems at key ‘weak points’ of the grid (e.g. key substations or aging transmission lines) will increase their impact and any Value for Money analysis.

South Africa has built upon the success of its market leading Kenhardt BESS project, with 13 projects since selected under the BES IPP programme’s Bid Window 1 and Bid Window 2. Alongside ESKOM’s own sites, this programme is encouraging private sector investment and driving competitive tariffs, at strategic grid locations.

What needs to happen next

Kenya must act decisively:

  1. Define regulatory frameworks: Clear licensing, monetization and procurement rules will de-risk investment and promote competition and investment. Learnings from international and regional programmes, such as BESIPP, can only help.
  2. Encourage private sector innovation: Incentives and risk guarantees (e.g. ATIDI, GuarantCo, Dhamana) can crowd in both foreign and local capital. Transparent Public Private Partnerships can enable the deployment of large scale infrastructure in a manner that is beneficial for both tax payers as well as investors
  3. Promote local assembly & skills development: Companies like Canto, Roam and BasiGo show what’s possible with the BESS supply chain in Kenya; let’s expand the ecosystem further.
  4. Place BESS at key grid nodes: Instead of individual IPPs shouldering the cost and pivoting their technical expertise, strategic grid-wide storage hubs (acting as Virtual Power Lines and Ancillary Service Providers) can ease congestion and improve scalability, utilising technology leaders with existing experience in the delivery of BESS.

Final thoughts:

Kenya is already a champion of renewable generation. With the right mix of policy, innovation, and investment, it can become a continental leader in energy storage too. BESS can not only stabilise the grid but also accelerate investments into Kenya’s abundant renewable resources for domestic and industrial use and for export.

Let’s not just generate clean power—let’s make sure we keep it for when it is most needed.
