Nyika Hydropower Group Limited (NHG) has signed a Transmission Connection Agreement with the Electricity Supply Corporation of Malawi (ESCOM). The agreement formalises how the planned 51MW North Rumphi Hydropower Cascade will connect to Malawi’s national grid. The project is a run-of-river development on the North Rumphi River in Rumphi District, comprising three schemes: the 13MW Phoka, 18MW Munonono and 20MW Chiweta plants.
According to NHG, the cascade is expected to generate about 276,000MWh of electricity per year. NHG estimates the cascade could serve demand equivalent to about 2.7 million people. It would also increase Malawi’s installed generation capacity by roughly 9.2%.
Grid deal anchors a rare hydro diversification
Industry reporting describes North Rumphi as Malawi’s first large hydro plant not sited on the Shire River, where most existing hydropower capacity is concentrated. As a result, the project points to genuine geographic diversification of hydro resources. That matters in a system that has seen repeated drought-related outages on Shire River plants.
The grid agreement follows the signing of 25-year power purchase agreements in May 2025, which locked in long-term offtake for the project. Together, the PPAs and Transmission Connection Agreement give the project a clearer commercial and technical framework. With firm grid access and contracted revenue, NHG has signalled that it will now focus on completing remaining project agreements, detailed engineering and financing work to reach financial close.
For investors, this sequence reduces development risk. It also indicates that the project is moving into a more bankable phase.
What does the Malawi hydro deal mean for investors?
Under the agreed connection plan with ESCOM, the cascade will be built and connected in phases. This allows early power delivery while the full scheme is completed. In the first phase, the Phoka plant will connect at 66kV through a short loop-in/loop-out line into the Livingstonia–Bwengu transmission line.
Later, double-circuit 33kV lines will link Chiweta to Munonono and then on to the planned Haniniya substation. Power will be stepped up and transmitted at 132kV to New Bwengu over a new 54km line. This design helps stage capital deployment and supports progressive revenue generation, which is attractive to lenders and equity backers.
Meanwhile, Malawi is trying to ease power deficits by importing up to 50MW from Mozambique over a new interconnector, with potential future imports of 100–200MW. At the same time, EGENCO and government partners are pushing battery energy storage and new solar capacity to cut reliance on Shire River hydropower. In this context, North Rumphi’s contribution looks modest in absolute terms but significant for resilience: it expands capacity, shifts part of the supply base away from one river system, and adds a private-sector run-of-river asset structurally aligned with climate risk concerns.
The deal also sits alongside the larger 350MW Mpatamanga Hydropower Project on the Shire River and EU-backed investments aimed at rehabilitating existing hydropower and strengthening Malawi’s grid. Therefore, Malawi’s generation and transmission pipeline now includes a mix of large river-based dams, smaller cascade projects, solar plants and cross-border interconnection. Across the region, similar trends are reshaping how utilities and investors approach long-term power contracting, as the Eastern Africa Power Pool’s $40bn trading ambitions illustrate.
For institutional investors, that mix signals gradual normalisation of project structuring. Long-tenor PPAs, clear grid plans and blended public–private financing are becoming more standard.
A more bankable power system takes shape
One analyst summary captures the investment angle clearly: Malawi’s latest hydro agreements show that the country is moving from ad hoc crisis responses towards a more bankable, diversified power system built around long-term contracts and targeted grid upgrades. As NHG turns to engineering and funding, investors will watch for progress on financial close, the timing of first power from Phoka, and how the project’s risk allocation compares with future Malawian independent power producers across hydro, solar and storage.
Quick answers
The North Rumphi Hydropower Cascade is a 51MW run-of-river hydropower project on the North Rumphi River in Rumphi District, comprising the 13MW Phoka, 18MW Munonono and 20MW Chiweta plants, expected to generate about 276,000MWh per year.
Nyika Hydropower Group Limited (NHG) and the Electricity Supply Corporation of Malawi (ESCOM) signed the Transmission Connection Agreement, following 25-year power purchase agreements signed in May 2025.
It is reported to be Malawi’s first large hydro plant not sited on the Shire River, diversifying the country’s hydro resources and adding roughly 9.2% to installed generation capacity while reducing vulnerability to drought-related outages.
