The Democratic Socialist Republic of Sri Lanka has received financing from the World Bank towards the cost of the Installation of a 75 MVA synchronous condenser at New Habarana GSS and intends to apply part of the proceeds for the following consulting services.

\n\n

The consulting services (“the Services”) include: (a) site assessment and data collection, including review of existing grid studies and operational data, and identification of technical;  spatial, and integration constraints; (b) evaluation of system requirements covering grid stability, reactive power and voltage control needs, future expansion scenarios, and determination of key synchronous condenser technical parameters, including excitation, flywheel sizing, short-circuit contribution, and environmental and seismic considerations; and (c) development of technical specifications and procurement support, including detailed specifications for design, auxiliaries, protection and control, SCADA integration, testing and commissioning, warranties and spares, and delivery of a structured knowledge-sharing program for National System Operator (NSO) staff. The detailed Terms of Reference (TOR) for the assignment is attached to this REOI.

\n\n

The assignment will be carried out by a multidisciplinary team of experts comprised of an Electrical Engineer / Synchronous Condenser Specialist, Mechanical Engineer (Large Rotating Equipment), Protection, Control and Automation Engineer (P&C/SCADA), and Grid Studies and Power Quality Specialist, with complementary expertise covering synchronous condenser design and performance, excitation and auxiliary systems, mechanical and vibration aspects of large rotating machines, protection and control systems for transmission substations, SCADA and communication interfaces, and power system stability and dynamic performance analysis. The assignment is expected to span 45 calendar days from the start date, with an anticipated commencement in first quarter of 2026.

\n\n

The NSO now invites eligible consulting firms (“Consultants”) to indicate their interest in providing the Services. Interested Consultants should provide information demonstrating that they have the required qualifications and relevant experience to perform the Services.

\n\n

The best qualified firm to carry out the services will be selected in accordance with the Consultant’s Qualifications Based Selection (CQS) method set out in the Regulations and based on the following criteria: (a) proven experience in power system studies and grid integration of synchronous condensers in high-renewable transmission networks; and (b) demonstrated experience in specification and design of synchronous condensers of similar size or larger.

\n\n

The attention of interested Consultants is drawn to paragraph 3.14, 3.16 and 3.17 of the World Bank’s Procurement Regulations for IPF Borrowers, sixth edition, February 2025 (“the Regulations”), setting forth the World Bank’s policy on conflict of interest.

Preparation of Technical Specifications for Installation of a 75 MVA Synchronous Condenser at New Habarana Grid Substation and Support with Procurement Process

\n\n

Terms of Reference

\n\n
    \n\t
  1. Background
    2. \n
\n\n

In line with Sri Lanka’s commitment to sustainable development, the government has set ambitious energy policy targets, aiming to achieve 70% of electricity generation from renewable energy sources by 2030 and reach carbon neutrality by 2050. Sri Lanka’s electricity demand is experiencing sustained growth driven by economic development, and tourism growth. In the meantime, the government aims to decrease dependence on imported fossil fuels and lower electricity costs by diversifying the energy mix and leveraging the country’s extensive renewable energy resources. These developments necessitate enhancements in grid stability, reliability, and operational flexibility to support both current needs and anticipated future expansions.

\n\n

In July 2025, the World Bank’s Board of Directors approved the Secure, Affordable and Sustainable Energy to Sri Lanka project (SASE, P505052), which will finance critical grid investments.  SASE is the World Bank’s flagship initiative aimed at strengthening Sri Lanka’s power sector infrastructure to deliver more secure, affordable, and sustainable energy to all citizens. The project encompasses the upgrade and expansion of transmission assets, integration of renewable energy sources, and the deployment of advanced technologies to modernize the grid. Within this broader context, the installation of a 75 MVA synchronous condenser at New Habarana Grid Substation has been identified as a critical investment.

\n\n

The New Habarana Grid Substation is a pivotal node in Sri Lanka’s national transmission network, strategically located to facilitate the transfer of bulk power between key regions. The synchronous condenser is intended to enhance system inertia, improve voltage regulation, and provide rapid reactive power support—functions that are vital for mitigating the volatility associated with higher penetration of renewable energy. The addition of this equipment aligns with the project’s strategic goals to ensure grid resilience, reduce vulnerability to disturbances, and facilitate the ongoing transition toward a cleaner energy mix. Furthermore, the New Habarana Grid Substation’s role as an interconnection point for multiple transmission corridors makes it a priority location for dynamic grid support measures. The synchronous condenser will enable the substation to help balance supply and demand fluctuations, support fault recovery, and meet stringent power quality standards as outlined in the project’s technical assessment.

\n\n

In recognition of these challenges and opportunities, engaging a qualified consulting firm to help Ceylon Electricity Board (CEB) prepare robust technical specifications for the synchronous condenser is essential. The Consultant’s work will guarantee that the procurement process is competitive and transparent, and that the delivered solution addresses the operational, environmental, and regulatory requirements detailed in the project’s foundational documents.

\n\n
    \n\t
