Advancing solar PV integration: A vision for a sustainable energy future

Published

on

During the Eng. (Prof.) R. H. Paul Memorial Oration 2025, Prof. Lilantha Samaranayake emphasised the urgent need for advanced solar photovoltaic (PV) integration to create a resilient and sustainable energy future. Speaking on the Future of Renewable Energy, he highlighted projections from the International Energy Agency (IEA) that forecast global renewable electricity generation will exceed 17,000 TWh by 2030, representing an almost 90% increase from 2023. Solar PV is anticipated to become the leading source of renewable electricity, followed by wind and hydroelectric power.

Sri Lanka has set an ambitious target of achieving 100% renewable energy. Policymakers are working towards a people-centric, equitable, and affordable energy transition. The government also aims to reduce electricity tariffs by 30% within five years, though no specific timeline has been set for net-zero emissions.

Challenges in Solar PV Integration—While renewable energy adoption is increasing, challenges remain. A major issue is grid stability due to solar energy’s intermittent nature. Grid stability refers to the ability of an electrical power grid to maintain a consistent voltage and frequency while balancing electricity supply and demand. One of the main challenges with integrating solar energy into the grid is its intermittent nature, meaning that solar power generation fluctuates depending on sunlight availability. This variability can cause instability in the grid.

Why is Solar Energy Intermittent? Solar panels generate electricity only when exposed to sunlight. At night, there is no generation, requiring alternative power sources. Cloud cover, rain, and seasonal changes affect solar energy output. On cloudy days, solar generation can drop suddenly, causing fluctuations in power supply. Unlike conventional power plants that provide a steady output, solar energy can vary within minutes, making it challenging to maintain a stable power flow.

How Does This Affect Grid Stability? The Electricity grids operate at a specific frequency (e.g., 50 Hz or 60 Hz). A sudden drop in solar power generation can lead to a decrease in frequency, potentially causing power outages. Solar energy injections can cause voltage levels to rise or drop unpredictably, affecting equipment performance and consumer supply quality. Traditional power plants have rotating generators that provide inertia, helping to stabilise the grid. Solar PV systems do not have this natural inertia, making the grid more susceptible to instability.

Prof. Samaranayake explained that Sri Lanka’s current power generation mix, as of November 2024, includes:

27% from hydroelectric power

19.6% from rooftop solar

14.3% from coal

13.6% from oil

5.1% from private oil plants

Smaller contributions from wind, biomass, and other renewable sources

A key concern is the lack of inertia in renewable energy sources. Unlike conventional power plants, solar and wind do not provide inherent grid stability, leading to frequency fluctuations.

Prof. Samaranayake proposed an innovative solution for grid stability: implementing Virtual Inertia using advanced power electronic control systems. This approach mimics the stabilising effect of traditional rotating generators, ensuring a steady frequency supply in the grid.

Other potential solutions include:

Adding rotating machines such as LNG or nuclear power plants

Energy storage systems like pumped storage, flywheels, and large-scale battery systems

Enhancing grid regulations to support the integration of rooftop solar PV systems

The introduction of advanced Virtual Inertia technology is expected to complement regulatory changes that relax statutory voltage limits and improve the quality of electricity supply.

Another controversial yet forward-looking strategy discussed was the possibility of nuclear energy. According to sources from the Sri Lanka Atomic Energy Board (SLAEB), the country’s first nuclear power plant, leveraging integral pressurized water reactor (iPWR) technology, could be operational by 2032. Given Sri Lanka’s proximity to India, which already operates nuclear plants, proponents argue that nuclear energy could be a viable option for stabilizing the power grid.

Prof. Samaranayake stressed the need for a holistic approach, as solar PV continues to be vital to Sri Lanka’s energy future. This involves investing in energy storage, enhancing grid infrastructure, and enacting regulatory reforms. He called on policymakers, engineers, and the public to collaborate in creating a more sustainable and resilient energy landscape.

The Eng. (Prof.) R. H. Paul Memorial Oration reminds us of engineering and innovation’s critical role in tackling global energy challenges. With strategic planning and technological advancements, Sri Lanka can pave the way for a cleaner, more sustainable future.

The oration paid tribute to the late Prof. R. H. Paul, a distinguished academic and former Dean of the Faculty of Engineering, University of Peradeniya, who made significant contributions to electrical and electronic engineering in Sri Lanka. His legacy continues to inspire advancements in the energy sector.

EU’s new anti-greenwashing rules pose major challenge for Sri Lankan exporters

Published

on

This new directive applies to businesses across multiple sectors, of any size, that export products or services to the EU market.

Countdown to September 2026 begins

Sri Lankan exporters selling into Europe may soon face one of the most significant regulatory shifts in recent years as the European Union prepares to enforce sweeping new rules aimed at eliminating ‘misleading’ environmental and sustainability claims.

The regulation, known as the Empowering Consumers for the Green Transition Directive (EmpCo) – Directive (EU) 2024/825, will become fully enforceable across all EU member states from September 27, 2026. While the directive is primarily designed to protect European consumers from so-called ‘greenwashing,’ and it carries important implications for exporters worldwide, including those in Sri Lanka.

Compliance experts warn that many local businesses remain largely unaware of the new requirements despite their potential impact on market access, brand reputation, and regulatory compliance.

The directive introduces a simple but demanding principle: companies must be able to substantiate environmental and sustainability claims with credible evidence. Generic descriptions such as ‘eco-friendly,’ ‘green,’ ‘sustainable,’ ‘responsible,’ ‘carbon neutral,’ or ‘climate friendly’ may no longer be used freely unless they can be verified through reliable data and supporting documentation.

For Sri Lankan exporters, this represents a significant shift. Sustainability claims increasingly appear on product packaging, websites, social media campaigns, annual reports, tourism marketing materials, and corporate communications. Under the new framework, such claims could face scrutiny from regulators, consumers, retailers, and civil society groups.

The directive also places particular emphasis on future environmental commitments. Claims such as ‘Net Zero by 2040’ or ‘Carbon Neutral by 2030’ may require businesses to demonstrate clear implementation plans, measurable milestones, and systems for monitoring progress rather than relying on aspirational statements alone.

An environmental compliance expert told The Island Financial Review that this transforms sustainability from a communications exercise into a governance issue. “Responsibility will no longer rest solely with sustainability departments. Company directors, senior executives, marketing teams, procurement professionals, and compliance officers will all have roles to play in ensuring that public claims can withstand regulatory scrutiny. The potential costs of non-compliance are considerable. Under the directive, penalties may include fines of up to four percent of annual turnover generated within the relevant EU member state, restrictions on marketing activities, increased regulatory investigations, and challenges from consumer organisations and commercial partners.”

“The reputational consequences may prove even more damaging. In highly competitive export markets, trust has become a critical business asset. Companies found to be making unsubstantiated environmental claims could face long-term damage to relationships with buyers, retailers, and consumers.”

“The timing is particularly important for Sri Lankan businesses because compliance preparations, reporting frameworks and adjustments are needed before the enforcement date arrives.”

“Businesses supplying European markets are therefore being encouraged to begin assessing their exposure now rather than waiting until the last minute. Early preparation could help exporters safeguard market access, maintain buyer confidence, and strengthen their competitive position in an increasingly sustainability-conscious global economy.”

“For Sri Lanka’s export sector, the message from Europe is becoming increasingly clear: sustainability claims will no longer be judged by how compelling they sound, but by how convincingly they can be proven,” he said.

As the countdown to September 2026 begins, exporters may need to ask themselves a critical question: Are their sustainability claims ready for a new era of accountability?
