Bangladesh Renewable Energy Developer
Develop independent power projects as renewables become cheaper than new gas capacity.

The ask
Become Bangladesh's go-to independent power producer (IPP) for utility-scale solar and wind, originating projects of 20–200 MW, offtaking power purchase agreements from BPDB, and deploying capital as the country's fossil-fuel generation costs make new renewables the rational default.
Why now
Global renewables have crossed the threshold: new solar and wind are now cheaper than the operating cost of existing coal plants in most markets, and Bangladesh's new LNG-based gas plants are priced well above what solar can deliver. BPDB has committed to 40% renewables by 2041, but developer capacity to originate and de-risk projects lags far behind the target. The 2024–25 power sector reform opens the market to private IPPs in a way that was effectively closed for the past decade.
Why Bangladesh
Bangladesh's solar irradiation averages 4.5–5.0 kWh/m²/day — commercial-grade everywhere in the country. Rooftop demand is already large and growing; the utility-scale gap is where the capital need sits. Bangladesh is among the world's most climate-exposed nations: every tonne of avoided coal-fired generation has both local air-quality value and international carbon credit value. The country has an active carbon market relationship through the ADB and World Bank — certified emission reductions are bankable collateral for project finance.
As a business
IPP revenue is a 25-year PPA — predictable, inflation-linked, and bankable as project debt. Developer margin comes from the spread between all-in project cost (currently $0.55–0.70/Wp for utility solar in Bangladesh) and the PPA tariff negotiated with BPDB (target $0.045–0.065/kWh). A 50 MW project at ৳6/kWh tariff generates roughly ৳1.3B/year in revenue with 60–70% debt financing; developer equity IRRs of 18–22% are achievable with experienced project origination. The scaling play is a project pipeline — originate, develop to financial close, sell a minority stake to infrastructure funds, recycle capital.
Economics
Move the sliders to model a utility-scale solar IPP. Defaults are order-of-magnitude estimates — pressure-testing them is part of what a founder pitches us.

What ZEPH would back
A developer with at least one executed PPA or letter of intent from BPDB, land control for a site, and a grid interconnection study in hand. We are open to co-developing the first project alongside a founder who has the regulatory relationships but needs development capital to carry land, permitting, and engineering costs to financial close.
Impact
A 50 MW solar IPP operating at 20% capacity factor generates 87.6 GWh/yr and displaces approximately 68,000 tCO₂e annually versus Bangladesh's grid emission factor. At a 200 MW portfolio (four plants), annual avoidance exceeds 270,000 tCO₂e — equivalent to removing 58,000 cars from Dhaka roads. Each MW of solar commissioned displaces roughly $600,000/yr in LNG import costs at current BPDB generation mix, creating a compelling sovereign FX-savings argument that development banks will underwrite. Independent solar IPPs also anchor the local engineering and O&M workforce that Bangladesh's 40% renewable target requires.
