Vajra small hydro project (SHP) is a run-of-the-river small power project, where water from the river is diverted through the power house to generate renewable power. Whereas Chaskaman SHP is a dam toe project set up on an existing dam. . Together these projects have an installed capacity of 6 MW (3 MW each). The project activity is generating electricity and wheeling it to INOX air products limited through Maharashtra state electricity grid.

The aims and objectives behind the implementation of the projects are given as follows:

  • Sustainable development, through utilization of renewable hydro resources available in the project region.
  • Rural area development since the projects is in the rural area.
  • Capacity addition to the present installed capacity and increase in the energy availability.
  • Generation of additional employment.

The ultimate aim of the project is to gain total CO2 emission reduction of 191,322 tons.

Now, the technologies behind the hydro project are stated as follows:

  • The technology or power generation process uses hydro resource and converts the potential energy available in the water flow into mechanical energy using hydro turbines and then to electrical energy using alternators.
  • The technology employed is the small hydro turbines used for hydroelectric power generation. The installed capacity on small hydro power plant is 3.0 MW each, i.e.; (6,0 MW in total).
  • The technology is the Kaplan ā€˜Sā€™ type hydro turbine. The generation voltage at the generator terminals is 11 kV, which is being stepped-up to 100 kV at Vajra site and 33 kV at Chaskaman site to match the nearest substation voltage level.

About Varja Small Hydro Power Project:

The project site is located 6 km downstream of Bhatsa dam. The small hydro power project is installed on a natural river fall which is about 12.5 metre in height.

  • The rated capacity of the plant is 3 MW and the generation voltage is 11 kV. It is stepped up to 100 kV by a power transformer and connected to 100 kV line of MSEB, 500m away from plant through a breaker for evacuation of power.

About Chaskaman Small Hydro Power Project:

The project site is located at Bibi Taluka Rajgurunagar, District Pune Maharashtra, India. The small hydro power project is installed above the main canal which is a part of existing dam. Power generated by this installation is 1 x 3.0 MW.

  •  The rated capacity of the plant is 3 MW with a 33% continuous overload provision and the generation voltage is 11 kV. It is stepped up to 33 kV by a power transformer and connected to 33 kV MSEB sub-station about 5 km away from the plant.

The contribution and changes to the people which this project will be providing in the coming are estimated as follows:

  •  Since this project is in a rural area, it has already initiated the development of the region. It has helped to improve the conditions of the roads connecting site and nearby villages to existing roads.
  • Generated employment opportunities for the local people, both during construction and operation phases.
  • This project is based on the usage of renewable hydro resources for power generation; it does not lead to any emissions in the environment. The project activity is a step towards environmental sustainability by saving exploitation and depletion of a natural, finite and non-renewable resource like coal/gas.
  • The project has created a business opportunity for local stakeholders such as suppliers, manufacturers, contractors etc.

Location: Maharashtra
