Driving Sri Lanka’s Clean Energy Transition: The WindForce Story

Diyajanani Floating Solar Project

BESS Facility in Anuradhapura

As Sri Lanka marks World Sustainability Day 2026, few local success stories illustrate the country’s clean energy progress as clearly as WindForce PLC. What began in July 2010 as a team of five members with a single ambition, to drive and manage renewable energy development in Sri Lanka, has grown into the nation’s largest Independent Power Producer (IPP) in the renewable energy sector, with an installed capacity of 288 MW spanning wind, solar, mini hydro and battery energy storage (BESS).

Since commissioning its first wind power project in 2010, WindForce has built an enduring presence across Sri Lanka’s energy landscape, managing the full life cycle of renewable projects, from feasibility studies and engineering design through to construction, commissioning, and long-term operations and maintenance. That growth has been underpinned by a strategy balancing short, medium and long-term priorities, delivering sustainable growth while safeguarding stakeholder interests. The footprint has since expanded beyond Sri Lanka’s shores, with wind, solar and hydro assets now operating in Pakistan, Uganda and Ukraine, reflecting the Company’s ambition to grow as a regional renewable energy player while staying firmly rooted in its home market.

This growth has been driven by a team of skilled professionals with deep expertise across engineering, procurement, construction and operations, leveraging advanced technologies to deliver efficient, environmentally responsible energy solutions that meet international standards.

This year has been a particularly significant one for the Company’s growth pipeline. In September 2026, WindForce commissioned Diya Janani (Pvt) Ltd, a 5 MW floating solar power project at the Dambulu Oya Reservoir and one of Sri Lanka’s pioneering private sector floating solar developments. Built on water rather than land, the project reflects a growing shift towards innovative, land efficient solar solutions, adding a new dimension to the Company’s diversified renewable portfolio.

The same month saw WindForce reach a landmark in energy storage, commissioning the Anuradhapura Battery Energy Storage System (10 MW/40 MWh), the first completed facility within a wider portfolio of thirteen standalone BESS projects (130 MW/520 MWh) secured under Sri Lanka’s first grid-scale BESS initiative, led by the National System Operator (Pvt) Ltd. This momentum continued into October, with the commissioning of two further BESS facilities in Mahiyanganaya and Vavuniya (20 MW/80 MWh). Development and implementation work continues steadily across the remaining locations, with each facility built under a 15-year Build, Own and Operate model. Together, these projects represent a combined investment exceeding Rs. 22.5 billion and are expected to play an important role in enhancing grid stability, supporting renewable energy integration, and easing pressure on the national grid during periods of peak evening demand.

Beyond its operating assets, WindForce maintains a robust development pipeline exceeding 260 MW. The 100 MW Rividhanavi Solar Park in Siyambalanduwa continues to progress towards implementation, while the proposed 50 MW Mullikulam Wind Power Project through Aeroforce (Pvt) Ltd and a 10 MW wind power project being developed through Safe Power International (Pvt) Ltd remain under active development. Collectively, these projects underline the Company’s continued commitment to diversifying its generation mix and strengthening Sri Lanka’s long term energy security.

Looking ahead, WindForce has also been exploring ways to expand the role of energy storage within its existing solar footprint. Six of its project companies recently participated in a Government tender for 150 MW / 600 MWh of Battery Energy Storage Systems to be integrated with existing ground mounted solar PV plants on a Build, Own and Operate basis. The bids submitted fell within the winning threshold, representing a potential additional BESS capacity of 28 MW / 144 MWh. While the formal award process is yet to be completed, the Company views this as a natural extension of its existing solar assets, should it materialise.

As Sri Lanka continues its transition towards a cleaner, more resilient power system, WindForce’s journey, from a small team with a single wind project to the country’s largest renewable energy IPP, reflects the kind of long term, patient investment that sustainable development requires. It is a journey built not only on megawatts, but on a sustained commitment to economic, environmental, social and governance responsibility. With a diversified portfolio across wind, solar, mini hydro and BESS, and a pipeline that continues to grow, the Company remains focused on supporting Sri Lanka’s renewable energy ambitions while contributing to enhanced grid stability, energy security and sustainable economic growth for the years ahead.
