OPERATIONAL OVERVIEW
Pioneering Peak
Performance
Avon and Dedisa Peaking Power collectively bolster the energy grid with a substantial contribution of over 1,005 MW, enhancing energy stability and security.
As open-cycle gas turbine facilities, both Avon and Dedisa play a pivotal role by providing electricity during periods of peak demand. Beyond their primary function of offering crucial power backup, these plants underscore the significance of synergistic collaborations between the State and the Private sector.
Enter the Open Cycle Gas Turbine Power Plant
Open-cycle gas turbines are known for their reduced emissions, notably cutting down on pollutants like sulfur dioxides, carbon dioxide, and nitrogen oxides. This positions them as a more environmentally-friendly option in power generation.
Open-Cycle Gas Turbines (OCGTs) are globally recognized for their rapid power delivery capabilities. They can swiftly channel power to the grid due to their inherent design. These turbines can operate using diesel or gas as their energy source, and some even offer dual-mode functionality for enhanced flexibility.
Put simply, the facility compresses surrounding air, elevating its temperature and pressure. This compressed air is then ignited with fuel, converting it into a hot, fast-moving gas. These high-velocity, heated gases propel the turbine linked to a generator, producing electricity. This electricity is then adjusted to the appropriate voltage levels for grid distribution.

Our OCGT plants are designed to operate using gas fuel or in a dual-mode configuration employing both diesel and gas. Furthermore, these plants have been meticulously engineered to be adaptable for conversion to combined cycle (CCGT). Transitioning to CCGT typically amplifies the overall capacity by approximately 50%. In either configuration, the effective operation on gas is contingent upon its ample availability. Operating on gas notably reduces emissions in comparison to diesel-based operations. Historically, international gas prices have often been more economical than those of oil/diesel.
