Private Equity (PE) firms are investment funds that acquire significant ownership stakes, typically majority or substantial minority positions in established, more mature companies.
Unlike venture capital, which focuses on early-stage, high-risk ventures, private equity targets companies that have already demonstrated proven business models, consistent revenue streams, and often positive cash flows.
Core characteristics include:
- Significant Stake Acquisition: PE firms usually seek controlling or influential stakes (often 51% or more) to drive strategic direction.
- Operational Value Creation: Emphasis on improving efficiency, scaling operations, strengthening governance, and optimising costs and revenue.
- Finite Investment Horizon: Investments are typically held for 3–7 years, with a clear exit strategy through IPO, strategic sale, or secondary buyout.
- Active Involvement: PE teams frequently take board seats and work closely with management to implement growth plans and operational improvements.
- Leveraged Capital: Many transactions involve a combination of equity and debt financing.
Relevance to Climate Tech and Cleantech
Private equity firms are becoming increasingly active in the climate tech and cleantech sectors, particularly in scaling established businesses and project portfolios.

Their relevance includes:
- Scaling Mature Cleantech Companies: PE capital is well-suited for companies that have moved beyond the pilot stage and require significant capital to expand operations, enter new markets, or consolidate market share.
- Project Portfolio Development: PE firms invest in portfolios of renewable energy projects (solar, wind, mini-grids), clean energy infrastructure, and sustainable agriculture or waste-to-value businesses.
- Operational Improvements: They bring expertise in supply chain optimisation, project execution, regulatory navigation, and financial structuring—critical for making cleantech projects bankable and profitable at scale.
- Energy Transition Plays: PE is active in both renewable energy generation and enabling technologies such as battery storage, electric mobility infrastructure, and green hydrogen.
- Exit Readiness: PE helps prepare cleantech companies for IPOs or strategic sales, attracting further capital into the sector.
In Africa, PE activity in cleantech is growing as the sector matures, shifting from grant-heavy or early-stage financing toward growth-oriented and buyout-style investments.
Real-World Examples in African Climate Tech / Cleantech
- Starsight Energy (West Africa): Received significant mezzanine and growth capital from British International Investment (BII) to scale its commercial and industrial solar portfolio in Nigeria and Ghana.
- Powerhive (Kenya): Attracted PE-style growth equity to expand its solar mini-grid portfolio across East Africa.
- Zola Electric (formerly Off Grid Electric): Transitioned from venture capital to PE-backed growth phases to scale its solar home systems and mini-grid operations.
- Sun Exchange (South Africa): Uses a blend of crowdfunding and PE-style investment to finance and scale solar panel leasing for commercial clients.
- BioTherm Energy (South Africa): A leading renewable energy developer that has attracted private equity for utility-scale solar and wind projects.
Firms such as Actis, Helios Investment Partners, African Infrastructure Investment Managers (AIIM), British International Investment (BII), and Norfund have been particularly active in African cleantech, focusing on operational scaling and project portfolio development.
Strengths and Limitations
Strengths:
- Provides large amounts of growth capital for scaling proven cleantech models.
- Brings operational expertise and governance improvements essential for project execution.
- Supports consolidation of fragmented renewable energy markets.
- Creates credible exit pathways that attract more capital into the sector.
Limitations:
- Less suitable for very early-stage, high-risk climate innovations.
- Requires companies or projects to have reached a minimum level of revenue or operational maturity.
- Investment horizons and return expectations can sometimes conflict with long-gestation climate projects.
- Higher leverage in some deals can increase financial risk in volatile markets.
Looking Ahead
Private Equity firms play a vital role in the climate tech and cleantech ecosystem by acquiring significant stakes in more mature companies and project portfolios to drive operational improvements and scale.
In Africa, PE is increasingly supporting the transition from pilot-stage renewable energy and clean technology initiatives to commercially viable, large-scale deployments.
While venture capital and development finance institutions dominate early-stage cleantech funding, private equity provides the growth capital, expertise, and discipline needed to build sustainable businesses and infrastructure at scale.
As Africa’s clean energy transition accelerates, PE activity in this sector is expected to grow significantly.
