As part of the turnkey contract, ABB will design, engineer, supply and commission the substations and provide high-voltage air-insulated switchgear, medium-voltage indoor gas-insulated switchgear, power transformers, IEC 61850-compliant protection and substation automation, and fiber-optic communications systems.
The Sri Lankan government plans to install additional power generation capacity of over 2,500 MW and to increase the share of renewable energy in the national grid to about 20 percent by 2020.
The new infrastructure is being deployed as part of the country's Clean Energy and Network Efficiency Improvement Project, which aims to strengthen the national grid by increasing capacity and enabling greater integration of renewables as well as reducing losses and enhancing power reliability, the release said.
"We are pleased to support Sri Lanka's efforts to develop a reliable grid. These substations will address the growing demand for electricity and boost transmission capacity," ABB India Managing Director Bazmi Husain said.
