Startling revelations have come to the fore as to how the present administration of the Ceylon Electricity Board (CEB) is attempting to promote thermal and coal power by curtailing renewable power generation.
For the first time in the history the CEB, it has switched off all rooftop solar plantsa over 100kW and instructed all rooftop and ground mounted solar system owners to switch off their inverters voluntarily to ensure the reliable and stable operation of the national grid during recent New Year season. The CEB claimed that this decision was taken due to the significantly low demand observed in the system.
However, most of the roof top solar owners disregarded this unusual directives. It is now reported how the CEB Engineers have forcibly entered ground mounted solar farms in many parts of the country during the festive season and switched off their inverters from 9am to 4pm for five consecutive days.
Giving various unacceptable explanations as to why Renewable Energy (RE) has to be curtailed, the CEB maintains that this curtailment was facilitated to maintain an adequate level of dispatchable generation and improve sufficient system inertia.
“All these unacceptable explanations are given perhaps for two reasons. The first could be to conceal their inability to manage the system and the second reason is because a group of CEB officials connected to the diesel mafia are heavily losing their ‘income’ when electricity is generated from solar. When coal and thermal generations are minimised, these vested parties do not get their ‘commission’ as solar generation does not benefit them although it benefits the country. This is the first time orders were given to switch off not only roof top solar inverters, but also ground mounted solar as well,” a highly reliable source from the Sustainable Energy Authority told this newspaper.
Development Master Action Plan
Sri Lanka Sustainable Energy Authority (SLSEA) and the CEB drafted the ‘Renewable Energy Development Master Action Plan (REDMAP) 2023/ 2026’ in 2022 highlighting the importance in adding renewable energy (RE) to the national grid, especially from wind and solar. This was part of the Long-Term Generation Plan (LTGEP) that was drafted in line with the government’s policy to target achieving 70% RE by 2030, and to ensure timely implementation of RE additions to the system. CEB’s decision to ignore the instruction given in these reports and purchasing diesel and coal at a higher cost has raised eyebrows amongst their own engineers.
“When purchasing solar power, we- the CEB -- pay them with rupees whereas we have to pay in dollars when purchasing coal or diesel power to procure the fuel. Just because this group of CEB Engineers are receiving commissions from this coal and diesel generation, but not a cent from solar generation, they opt to purchase power generated from coal and diesel,” sources said.
As per the REDMAP, the proposed plan was to generate 1,795MW solar and 575 MW wind and other RE from 2023 to 2026. Having issued a report as such, what was the reason for the CEB to curtail RE and go ahead with costly thermal and coal power?
“When drafting the REDMAP, Consultancy service to the Asian Development Bank (ADB) was provided by the Resource Management Associates (Pvt) Ltd (RMA) which is also known as RMA Energy, which was headed by the present Chairman of CEB Dr. Thilak Siyambalapitiya until September 2024 and presently by his wife.
RMA Energy provides consultancy services to ADB and World Bank (WB) on the country’s power sector. Having recommended to add more RE generation to the national grid at the time the report was drafted, this decision was ignored once he became CEB chairman and he wanted to purchase costly coal and thermal power by curtailing RE generation. It was even alleged that he was attempting to tender rooftop solar and ground mounted solar which is less than 10 MW for an unknown reason,” the Sustainable Energy Authority source told on condition of anonymity.
As per the CEB and Public Utilities Commission of Sri Lanka (PUCSL) official data, from the time the REDMAP was issued and up to now only 793 MW Solar plants have been commissioned, a figure which includes rooftop solar units.
US$ 1 million paid
According to sources, it was the ADB that gave the grant to prepare this report ‘Way Forward of Integration of Renewable Energy Resources to the National Grid from 2023 to 2026 by Means of Appropriate Business Models’. Director General Power Sector Reform Secretariat and member of the Energy Committee, Eng. Pubudu Niroshan Hedigallage, has made a status most on his Face Book account, adding that US$ 1 million has been paid to RMA Energy for the consultancy services provided.
However, when this newspaper contacted Eng. Hedigallage to find out about the US$ 1 million payment to RMA Energy for the consultancy service provided for this project, and also to know how Dr. Siyambalapitiya could change his stance regarding RE addition to the grid after assuming duties as Chairman CEB, the former accused this newspaper of slinging mud at him.
“I know who is behind this mud slinging campaign. You can write anything you want, but I am not scared of mud slinging,” Eng. Hedigallage said.
Meanwhile questions have been raised as to how Dr. Siyambalapitiya’s wife Namalee Siyambalapitiya continued to work for RMA Energy in the capacity of director even after the former had resigned from his post to accept CEB Chairmanship.
“RMA earns hundreds of thousands of Dollars from these consultancies annually related to Sri Lankan power sector. What sought of conflict-of-interest policy has he adopted before he took over office at CEB? Has he divested of his interest in RMA Energy? Has his wife divested of her interest in RMA Energy? Have they resigned from all operations of RMA Energy and handed over the RMA Energy Management and technical control of the company? Since RMA is currently consultants to Offshore Wind Power on pre-feasibility assessment, have they recused themselves from this engagement or any project related to the country’s power sector? Is Tharaka Siyambalapitiya who is the senior project engineer of this company an offspring or a relative of the CEB Chairman?
