Super Efficient Cogeneration Systems
www.tesplcogen.com

A Cogeneration system involves simultaneous generation of multiple useful energy sources like power, heat, refrigeration/ cooling, water recycling, evaporation and drying. TESPL offers super efficient cogeneration systems for all industries under two categories, Captive Cogeneration and Distributed Cogeneration

Captive Cogeneration

Cogeneration involving simultaneous generation of multiple useful energy sources viz. power, heat, refrigeration / cooling, water recycling, Evaporation and Drying. Industries go for Captive Cogeneration due to following principle reasons.

  • To reduce power and other energy costs.
  • To improve productivity and reduce costs of production through reliable uninterrupted availability of quality power from Cogeneration plant.
  • Cogeneration system helps to locate manufacturing facility in remote low cost areas.
  • Improves energy efficiency, and reduces CO2 emissions therefore it supports sustainable development initiatives.
  • The system collects carbon credits which can be traded to earn revenue.
  • Due to uninterrupted power supply it improves working conditions of employees raising their motivation. This indirectly benefits in higher and better quality production.
  • Cogeneration System saves water consumption & water costs.
  • Improves brand image and social standing.
TESPL Cogeneration systems are specially designed to suit each individual application, to cater to its peculiar energy demand pattern. Transparent Cogeneration Systems would see accelerating demand on account of rapid deregularisation of electricity markets worldwide.

Distributed Cogeneration

It is now worldwide trend to take recourse to “Distributed Generation” in preference to the large interconnected networks.
This concept called Distributed Cogeneration Systems (DCS) has gained tremendous importance worldwide and particularly in North America and Europe due to following reasons.

  • DCS enables multiple sources of revenue earnings e.g. in addition to power the project can sell steam, refrigeration, recycled water, desalinated water etc.
  • Multiple sources of revenue are vitally important for power projects particularly operating on costly petroleum fuels. In DCS cost of fuel gets distributed on all these energies making the tariff of each of these energies more reasonable and therefore attractive for the purchaser.
  • Biomass based cogeneration projects are renewable energy projects. Biomass based cogeneration systems reduce NOx emissions due to reduced flame temperatures in boilers.
  • All cogeneration projects are classified under “sustainable development initiatives”, as they help reduce CO2 emissions and earn carbon credits. Trading of carbon credit is going to be a real phenomenon in very near future. These projects being clean energy initiatives, help restore already off balanced ecological equilibrium.
  • Cogeneration projects are also water saving projects. This is because heat from exhaust steam of steam turbine is not directly rejected in cooling tower but it is either sold to consumers or used for driving Ammonia Absorption Refrigeration Plant (AARP) which in turn can drive Cold Storages, Ice plants, AARP has one unique feature that it can be air-cooled and therefore the feasibility and location of the project doesn’t critically depend on availability of water.
