What Anergi Group does

Anergi Group is a privately-held, African-owned power infrastructure company that develops, finances, owns, and operates electricity generation assets across sub-Saharan Africa. The company was originally established in 2004 as Aldwych International Limited, was wholly acquired in 2008 by Pan-African Infrastructure Development Funds managed by Harith General Partners, and was rebranded as Anergi in Mauritius in 2017–2021. Anergi is the holding entity for a portfolio of six power generation assets spanning thermal (gas, dual-fuel, combined-cycle gas turbine) and renewable (wind, solar) technologies, with a combined gross capacity of approximately 1,518 MW across Ghana, Kenya, Nigeria, South Africa, and Sierra Leone. Its generation stack includes Azura-Edo IPP (461 MW, Nigeria), Kelvin Power (360 MW, South Africa), Lake Turkana Wind Power (310 MW, Kenya — comprising 365 turbines and ~17% of Kenya's installed capacity), Twin City Energy (200 MW, Ghana), Rabai Power Plant (90 MW, Kenya), and the Nant Project (108 MW under construction in Sierra Leone, with financial close reached in November 2024 and first power targeted for Q3 2027).

The company monetises capacity through 20–25 year Power Purchase Agreements (PPAs) with sovereign and quasi-sovereign counterparties — including EDSA in Sierra Leone, KPLC in Kenya, GRIDCo and the Volta River Authority in Ghana, Benin Electricity Distribution Company / Edo State Government in Nigeria, and the City of Johannesburg — providing contracted, predictable revenue denominated in USD or local currency. In 2025, Anergi extended its go-to-market beyond utility-scale grid offtake by co-creating Decentralised Energy Limited (DEL) with Viathan, a distributed energy platform in Nigeria serving industrial, commercial, and residential customers via private electricity networks and virtual CNG pipelines. Anergi is also the co-founder (with Harith General Partners) of the $300 million Pan-African Renewable Energy Fund (PAREF), repositioning the group as both asset owner and capital allocator for Africa's energy transition.

Anergi is wholly owned by Harith InfraCo Ltd and the Pan-African Infrastructure Development Fund 2 (PAIDF-2), both managed by Harith General Partners, and is governed through board representation with day-to-day operations led by CEO Maria Stratonova (ex-Goldman Sachs). The group maintains corporate offices in London and a registered address in Ebene, Mauritius, while operating power assets and regional subsidiaries across West, East, and Southern Africa. Its competitive positioning rests on long-dated capital from parent funds, deep institutional relationships with DFIs (DFC, World Bank, Norfund, FMO, IFU, MCC, EBID), and a leadership team with multi-cycle IPP origination and financial-close experience.

Revenue model

1. Power Generation and Sale (PPA-based): Anergi generates revenue by developing, owning, and operating power generation assets across sub-Saharan Africa. Revenue is derived from long-term Power Purchase Agreements (PPAs) with national utilities, electricity distribution authorities, and government entities, typically spanning 20-25 years. The PPAs provide contracted, predictable revenue streams denominated in USD or local currency. Additional revenue comes from operating and managing power infrastructure for portfolio companies.
