Identifying the Opportunity of using Gas Engines for Peaking Load Solutions
The client, a supplier of decentralised power plants for industries, utilities and independent power producers (IPPs) in India, had installed over 250 decentralised power plants in India generating around 3100 MWs and provided peaking solution plants, which have a higher efficiency than existing plants. The top management requested UC to quantify the opportunity in efficiency related savings on a pan-India basis by using their peaking load solutions.
To identify the opportunity of using gas engines for peaking solutions, UC adopted the following approach:
- Conducted rigorous analysis
1) Gained insights into data pivots like maximum load, minimum load, unrestricted demand, time of peak demand etc.
2) Prepared a representative overall load duration curve and determine base/ peak load requirements
- Outlined the potential applicability of the client’s solution at different load requirements
1) Based on load pattern analysis, mapped the applicability of the client’s solution at different load requirements
2) Gained insights into the efficiency of a particular based solution under different scenarios
- Quantified benefits
1) Determined efficiency of the existing power generation mix and that of a proposed optimum generation mix
2) Environmental savings arising out of less utilisation of water, land and a reduction in carbon emission were also estimated.
The client received an electricity demand analysis for the state of Maharashtra, a projection of the unrestricted load duration curve for 2016-17 based on the Central Electrical Authority’s Electric Power Survey projections, and the unrestricted Local Distribution Companies 2009, and quantified the benefits of using gas engines as a peaking solution in terms of energy and environment saving.
