Thanks to its pivotal role in the value chain, its expertise and its commitment to the energy transition, we are an effective advisor not only to all its stakeholders but to all civil society as well.

One of the goals of ours is to increase public knowledge about energy management. It therefore allocates part of its resources to supporting research programs on new development models for energy efficient solutions, behaviour studies, or new equipment in home automation, heating, ventilation, etc. and share this information and techniques with the public in an effective manner.


  1. 1. Energy Efficiency Improvement in Establishments

Continuous energy efficiency improvement and conservation programmes in industrial and commercial sectors are very important to realise energy savings in the particular sectors. We are implementing a long-term programme catering to this need, and Energy Managers appointed by institutions in these sectors under the relevant regulatory provisions, coordinate and implement the programmes under the guidance of our organisation. Capacity building, project implementation assistance by way of providing the necessary technological guidance, etc. are provided by us.

Accredited Energy Auditors provide technical assistance and advice for implementation of energy efficiency improvement measures in major energy consuming institutions. Energy Services companies (ESCos) are involved in carrying out energy audits and implementation of energy efficiency improvement projects. ESCos that are under registration with us are the approved companies for providing the particular services. Further, for capacity building of energy managers and energy auditors, institutes providing such services are assessed for their capacity in the relevant subject and their calibre in conducting training programmes at prescribed standards and registered for conducting such training programmes.

Most of the energy management activities are engaged with measuring and recording of energy usage. Hence, availability of measuring equipment without any shortage and affordable cost is of paramount importance for ESCos as well as energy consuming organisations. Therefore, to cater to the requirements of institutions, consultants, professionals and ESCos, a well-equipped instrument bank is maintained by us.  

Energy auditing and consulting services has been identified as a key element in achieving energy consumption reduction targets. We provide services in energy auditing and related consulting tasks including ISO 50001 EnMSAudits in government and other organisations.

  1. 2. Establishment of Specific Energy Use (SEU) Benchmarks

Benchmarking is the practice of comparing the measured performance of a device, process, facility, or organisation to itself, its peers, or established norms, with the goal of informing and motivating performance improvement. When applied to energy use, benchmarking serves as a mechanism to measure energy performance of a single product or service over time. We have published energy consumption benchmarks for five key sectors. Based on survey inputs, targeting organisations to go for incremental levels of energy efficiency these benchmarks are revised, and the revised benchmarks are expected to be published this year. If a product or service performs lower than the standard, the benchmark offers a realistic energy goal. Then systematic energy management - establishing action plan, implementing strategies, monitoring energy consumption and continuous improvement - can be practiced.


  1. Data collection, processing, analysis and compilation
  2. Publishing of revised benchmarks

Benchmarking is useful for state and local government property owners and facility operators, managers, and designers. It facilitates energy accounting, comparing a facility's energy use to similar facilities to assess opportunities for improvement, and quantifying / verifying energy savings.

  1. 3. Energy Efficiency Improvement in Built Environment

Benchmarking energy consumption in commercial buildings is a basic element of an organisation's energy management strategy because you can't manage what you don't measure. Across many commercial building markets, the practice has become a standard operating procedure as energy costs and associated environmental and sustainability issues have raised awareness around the importance of energy management.

Catering to this, the Code of Practice for Energy Efficient Buildings was published in 2008. In recognition of the fact that energy efficient technologies are developing fast, the Code must be revised considering the modern technologies available in the market. Also, the minimum energy performance values mostly based on international standards have not been verified yet. Therefore, it is required to verify these values and update the specified limits and incorporate the new energy efficient technologies initially. With the revision of the Code, awareness and training programs will be carried out for professionals employed in the construction sector in order to make them adhere to the Code prior to making it mandatory. Public Awareness on energy efficient guideline for residencies will also be carried out.

  1. 4. Energy Conservation in Transportation

The transport sector is a key area of energy consumption. There have been certain initiatives for energy efficiency improvement in the transport sector; however, formal programmes for energy efficiency improvement are yet to start. Initiatives are being taken to introduce a broad programme in this line, and some of the interventions will be introduced this year.


  1. Preparing ToR for web-based tool for bus passengers
  2. Procuring a company to develop a web-based tool
  3. Purchasing of bicycles for distribution


  1. 5. Energy Efficiency Improvement in the Tea Industry

We initiate, promote, conduct and coordinate research, surveys and investigations regarding specific aspects of energy efficiency, conservation and management, as per clause 35 (h) of our Act. The tea industry, which is one of most important industries in Sri Lanka, needs modernisation. The tea withering process alone consumes about 2% of the country’s bulk electricity consumption. Fixing of efficient motors, VSDs can be done to reduce energy consumption. However, due to various configurations of the withering troughs the assessment of energy saving has been difficult. Therefore, it was proposed by the Tea Research Institute (TRI) to develop a standard withering trough, which would help in accurately evaluating the energy performance of new technologies. Therefore, the TRI with our assistance, expects to develop a standard withering trough including a modified duct, radiators, process control and spreading mechanism.

As a major step, we are designing a prototype of a standard tea withering trough which includes modified ducts, radiators, process controls and spreading mechanisms with the assistance of the Tea Research Institute, which would help in accurately evaluating the energy performance.

  2. Installation of withering fans with VSD
  3. Installation and testing of the sensors and control systems
  4. Training of factory officers and other stakeholders


  1. 6. Feasibility Study for Tri-generation in Industrial Zones

Tri-generation or Combined Cooling, Heat and Power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from a single source of energy. In this case, 80% of the energy of the primary fuel can be utilised for tri-generation. This is one of the best methods available for maximum utilisation of energy. In this context, we have decided to explore the possibilities of introducing tri-generation in industries.

We have carried out a feasibility study in tri-generation for the hotel industry in 2015. As an outcome of this, it has been identified that there is a potential for implementing tri-generation systems in industrial zones. Purpose of this project is to explore the feasibility of implementation of such a system locally, and to train and create awareness on the concept of tri-generation among stakeholders. The feasibility studies are planned to be conducted in the Katunayake and Biyagama export processing zones. The project is being implemented in collaboration with the Industrial Services Bureau (ISB).

In practice, tri-generation can be used as the process by which some of the heat produced by a cogeneration plant can be diverted to generate chilled water for air conditioning or refrigeration. An absorption chiller is linked to the combined heat and power plant to provide this functionality.

There are several benefits to tri-generation including:

  • On-site, high efficiency generation of electricity and heat
  • Reduced fuel and energy costs
  • Lower use of electrical energy during peak demand periods
  • The production of steam from hot water reusing the heat of the engine, for on-site usages
  • Significant reductions in greenhouse gas emissions
  • Absence of harmful chemical pollutants since water is used as the refrigerant
  • Beneficial for improving the building's overall energy efficiency

As such we are exploring the possibilities of introducing tri-generation for sectors such as hotels, textile and apparel and industrial zones and the final evaluation for the selection of proposals is in progress.

Final report of the feasibility study is presented to SLSEA, showcasing the virtues of a central thermal energy supply utility for industrial zones with added on-site power generation capability. Main contents of the report are Background data including Energy Survey, Details of the Factories selected for the survey, Energy Consumption Scenario at Biyagama Export Processing Zone (BEPZ), Combine Cooling Heating and Power (CCHP) Technology, Changes needed for the Energy Consumption at BEPZ, Proposed Tri-generation Architecture for BEPZ including detailed Technical and Financial Feasibility and Sensitivity Analysis , Evaluation of Technologies Abbreviations and the Annexures.
