In most of the situation the load demand of any particular region varies during the time of the day. The load increases at particular time in the morning and evening which affects the efficient operation of power generating equipment (Power Plant) hooked up to grid. Generally the large capacity power generating equipment are designed to operate at its best efficiency between 90 to 100 % load and there is a sharp decrease if the load goes down. This is more pertinent in case of mid size Gas Turbine plants operated on CCGT design. In many cases like in Thailand SPP Segment; where the Power generating station is located close to industrial zone , steam is also supplied from the power generating station by utilizing the waste heat. In these situations a Hybrid solution works out to be the most effective solution, utilizing the best efficiency of the generating equipment at all load regimes. With everyone realizing the benefits of decentralized and distributed power generation , a combination of CCGT and Recip Engines could deliver the best overall plant level efficiency, where the steady / continuous base load may be catered by the CCGT module and the peaking / fluctuating load is catered by the Recip engines - which due to its modular construction provides the desired flexibility as well as act as fast ramp up / ramp down source . Requisite steam may also be generated by utilizing the waste heat of the engine to support enhancement of the system efficiency as needed. This adds up to bottom line as well as overall ROI of the project while remaining competitive in tariff bidding.
