‘Dependence on solar panels hindering national power grid stability’

Published

By Ifham Nizam

As Sri Lanka accelerates its transition to renewable energy, particularly through the widespread adoption of rooftop solar installations, it is encountering significant hurdles in maintaining the stability of its national power grid.

While the country’s commitment to sustainability aligns with global trends, the increasing reliance on intermittent sources like solar energy has introduced complex challenges, especially during periods of low industrial demand such as weekends and holidays.

A senior electrical engineer, speaking to The Island Financial Review, raised alarm over the escalating frequency fluctuations and instability in the power system, particularly on sunny Sundays when energy demand plummets. The high penetration of non-despatchable renewable energy (NCRE), such as solar power, has reduced system inertia, putting the grid at a heightened risk of failure during these low-demand periods.

He said one critical example was on September 22, 2024, when the national grid registered its lowest demand of 670 MW at 10:53 AM. To keep the grid stable, the Ceylon Electricity Board (CEB) had to curtail 160 MW of solar power and other NCRE sources between 10:00 AM and 3:00 PM. This action was taken to elevate the grid demand to 820 MW, thus ensuring the dispatch of higher-inertia power plants that provide more stability.

Despite these efforts, the CEB has warned that continued low demand could lead to more frequent instances of under-frequency load shedding (UFLS). In extreme cases, the instability could even result in the tripping of large thermal power plants, such as the Lakvijaya Power Plant in Norochcholai.

The CEB has identified a series of interventions aimed at mitigating these risks and ensuring the power grid remains stable:

New Tariff Structures for Industries: The CEB proposes incentivized electricity rates for industries during weekends and holidays to encourage higher electricity consumption, helping to balance demand fluctuations.

Hydropower as a Stability Solution: Large hydroelectric plants, including Victoria, Kothmale, and Samanalawewa, could be operated in synchronous condenser mode, which would allow them to provide reactive power support without generating electricity, bolstering grid stability.

Gas Turbine Generators for Inertia Support: The operation of the Kelanitissa Gas Turbine 7, with its high inertia, in synchronous condenser mode is being considered to provide further grid stability.

Fast Frequency Response and Energy Storage: Investments in energy storage technologies such as battery energy storage systems (BESS), flywheel storage, and fast-acting gas turbines are seen as critical for stabilizing frequency fluctuations quickly.

NCRE Control Desk Implementation: A dedicated monitoring and forecasting unit for renewable energy generation will help to manage the fluctuating supply of renewable energy more effectively.

Review of Spinning Reserve Requirements: The CEB is reassessing the adequacy of the current hot spinning reserve of 5%, considering the growing proportion of renewable energy on the grid.

Regulatory Framework for NCRE Curtailments: The establishment of a regulatory mechanism to control the dispatch of renewable energy, particularly from plants larger than 5 MW, will be essential in ensuring grid stability.

Optimization of Power Plant Operations: The CEB is exploring ways to optimize the operations of hydro and thermal power plants, particularly concerning their minimum operating power levels and ramp rates, to increase the overall inertia of the system.

Business, economic heavyweights converge in Colombo

Published

on

Senior business leaders, economists and international development experts, alongside the Prime Minister of Sri Lanka, will headline the Sri Lanka Economic & Investment Summit 2026, organised by The Ceylon Chamber of Commerce on 12 and 13 October at the Shangri-La Colombo.

Krishnakumar, Chief Executive Officer, Reliance Consumer Products Ltd, who brings more than four decades of experience in the consumer brands and FMCG sectors. Having previously served as President of Coca-Cola India and Southwest Asia, with extensive experience in building businesses and driving growth across emerging markets, Krishnakumar, more popularly known as Kk, now leads Reliance Consumer Products as it expands across categories and builds new customer, partnership and market opportunities.

Day 2 will bring together four international perspectives across discussions on economic resilience, regional connectivity, sector growth and digital transformation.

Lilia Aleksanyan, Senior Country Economist for Sri Lanka at the Asian Development Bank, will open the day’s discussions with a focus on Sri Lanka’s economic resilience. Her work covers the country’s macroeconomic outlook, policy advice and macro-fiscal and financial-sector reform. Her international policy experience also includes roles at the French Ministry of Finance and the French Central Bank.

The Summit will then turn to Sri Lanka’s connections with regional markets, with P. D. Singh, Chief Executive Officer, India & South Asia, Standard Chartered Bank, delivering the keynote for the session on trade corridors and value chains. Singh counts close to three decades of experience in banking and finance, with senior leadership roles spanning Standard Chartered, JPMorgan Chase Bank and HSBC.

The Sector Deep Dives will bring international perspectives to discussions on healthcare and energy.

Tushar Shroff, Chief Financial Officer, Zydus Lifesciences Ltd, will deliver the keynote for the healthcare discussion, drawing on more than three decades of experience in corporate finance, strategic investment and financial transformation. His career spans senior finance and leadership roles with ABB, Piramal Healthcare, Intas Pharmaceuticals and Vedanta Group, giving him a broad perspective on the business and investment decisions shaping the healthcare sector.

For the energy-focused deep dive, Edore Onomakpome, Regional Infrastructure Industry Manager for Bangladesh, Sri Lanka and Nepal at the International Finance Corporation, will bring extensive experience in infrastructure investment and project finance across emerging markets. Since joining IFC in 2013, she has held senior roles across Africa and South Asia, including managing IFC’s infrastructure portfolio across 16 countries.

The Summit will conclude its keynote programme with Prime Minister Dr. Harini Amarasuriya, who will deliver the keynote for “Nation Building in the Digital Age.” The Prime Minister also oversees the Ministry of Education, Higher Education and Vocational Education, bringing a direct policy perspective to discussions on digital transformation, innovation, education and the skills needed for a changing economy.

Together, these perspectives will bring regional, international and policy insight to SLEIS 2026 as Sri Lanka considers how to strengthen economic resilience, attract investment, deepen regional connections and develop new sources of growth.

Held under the theme “Positioning Sri Lanka in a Changing Global Economy: Resilience, Reform, and the Future of Economic Policy,” SLEIS 2026 will take place on 12 and 13 October 2026 at the Shangri-La Colombo.

The Sri Lanka Economic & Investment Summit 2026 is supported by its valued sponsors and partners. Platinum Sponsor – Standard Chartered Bank Sri Lanka, Gold Sponsor – VISA Worldwide (Pvt) Ltd., Bronze Sponsor – South Asia Gateway Terminals (Pvt) Ltd., Strategic Development Partner – Asian Development Bank, Telecommunication Partner – Dialog Telecommunication, Television Partner – Dialog Television, Session Sponsors – David Pieris Motor Company (Pvt) Ltd., Hemas Holdings PLC, Sunshine Holdings PLC, International Construction Consortium (Pvt) Ltd., Microsoft Sri Lanka (Pvt) Limited, Official Logistics Partner – Hayleys Advantis Limited, Official Airline – SriLankan Airlines Ltd., Official Hospitality Partner – Shangri-La Colombo, Airline Partner – China Eastern Air Holding Co. Ltd.

Registrations for SLEIS 2026 are now closed. The Ceylon Chamber looks forward to welcoming participants to the discussions on Sri Lanka’s future trajectory on 12 and 13 October.
