POWER PLANT ENGINEERING CONSULTANCY

DESEIN, founded in 1965, is a multidisciplinary engineering organization providing international quality "Consulting Engineer" services. Desein has been involved with the growth of the Nation's Thermal Power Plant sector and has contributed substantially (~20% capacity) to the engineering and construction management of India's major thermal power plants. Our objective is rendering complete specialized services to the power sector covering all aspects of planning, engineering, procurement, project management, construction & commissioning supervision as well as operation & maintenance.

In other words, Desein provides total energy solutions and has more than 32,000 MW of comprehensive power engineering experience. Desein has a team of 500+ engineers comprising of mechanical, civil, structural, architectural, electrical, control & instrumentation, environmental, geological and information technology who converge their expertise and skills to provide a well coordinated engineering deliverables.

DESEIN provides services from concept to commissioning of fossil fuel fired power plants of ratings upto 800 MW single unit size. These projects are executed either on an Engineering, Procurement & Construction (EPC) basis or on a Non-EPC basis. In the case of EPC route, the complete project is executed by one or two main contractors. In the other case, project execution is done based on a large number of systems / packages being procured from different vendors / contractors. This requires preparation of well defined specifications and a great amount of coordination between many vendors and contractors to ensure execution of the project within the targeted schedule and budgeted cost.
