The Acumen Hardest-to-Reach (H2R) Initiative represents a bold leap in impact investing, with the Acumen Fund successfully raising $246.5 million to fuel clean energy access in sub-Saharan Africa’s most remote areas.
Launched as a blended finance strategy, this effort backed by the Green Climate Fund and other partners targets off-grid solar solutions for 10 million people by 2030.
Through Acumen Ventures and its patient capital approach, the initiative is transforming lives in regions where 600 million lack electricity, driving economic growth and sustainability.
The H2R Initiative: Bridging the Energy Gap
The Acumen Hardest-to-Reach programme, spearheaded by the Acumen Fund, focuses on the “last mile” of energy access rural communities overlooked by traditional infrastructure.
With $246.5 million secured on September 24, 2025, including a $100 million anchor from the Green Climate Fund, the initiative deploys catalytic capital to scale solar mini-grids and pay-as-you-go systems.
This blended model leverages grants, loans, and equity from Acumen PEII (Private Equity Impact Investing) to attract private investors, reducing risks in high-potential but underserved markets.
Acumen International plays a pivotal role, coordinating with local entrepreneurs to deploy affordable solar kits that power homes, schools, and clinics.
Early pilots in Kenya and Nigeria have lit up 500,000 households, cutting kerosene use by 70% and saving families $50 annually.
The Acumen Academy complements this with training for 1,000+ energy entrepreneurs, promoting a self-sustaining ecosystem.
As part of the broader Acumen community, the initiative empowers Acumen employees and partners to innovate on the ground, ensuring solutions fit local needs.
Why Sub-Saharan Africa?
Sub-Saharan Africa holds 60% of the world’s best solar resources, yet only 5% of global solar investment flows there. The H2R Initiative asks: Why are we not taking advantage of solar in Africa?
The answer lies in barriers like high upfront costs and sparse populations, which the Acumen Fund addresses through de-risked financing.
By 2030, H2R aims to mobilise $1 billion in follow-on capital, powering 10 million off-grid users and creating 50,000 jobs in solar manufacturing and distribution.

The Green Climate Fund’s involvement signals global commitment, blending $100 million in grants with Acumen Ventures equity to support scalable models.
In Tanzania, for instance, H2R-backed mini-grids have boosted school attendance by 20% via evening study lights, while in Uganda, solar irrigation has doubled crop yields for smallholders.
This patient capital from Acumen PEII ensures long-term viability, turning energy access into economic opportunity.
Building the Acumen Ecosystem
The H2R Initiative thrives within the Acumen community, where Acumen Academy courses equip leaders with skills in impact measurement and scaling.
Acumen employees, numbering 200+ across hubs in Nairobi and Mumbai, drive on-the-ground execution, collaborating with local innovators.
Acumen International extends this reach, forging partnerships with governments and multilaterals to align with national electrification plans.
Challenges like supply chain disruptions persist, but the initiative’s blended finance mitigates them by attracting diverse funders.
As Acumen Fund CEO Jacqueline Novogratz noted, “H2R isn’t just about lights,it’s about dignity and opportunity for the world’s poorest.”
With Oman’s renewable energy 2030-style ambitions, H2R positions Africa as a solar superpower.
A Brighter Future for Energy Access
The Acumen Hardest-to-Reach Initiative is rewiring sub-Saharan Africa one connection at a time, blending finance, training, and innovation through the Acumen Fund.
By tackling ‘Why are we not taking advantage of solar in Africa?’, it unlocks untapped potential, fostering resilient communities and sustainable growth. As Acumen Ventures scales, expect ripple effects across the continent’s energy landscape.
