Tata Power has an installed generation capacity of 1996 MW through green resources.
Harnessing Hydro Power: The Company has an installed hydro capacity of 693 MW. Tata Power and Norway-based SN Power entered into an exclusive partnership to develop hydro power projects in India and Nepal. The consortium bagged the "240 MW Dugar Hydro Electric Project" in Chenab Valley in Himachal Pradesh, India. Tata Power has a JV with the Royal Government of Bhutan under which it has commissioned a 126 MW Dagachhu Hydro Project with Druk Green Power Company in March 2015. Tata Power, through its subsidiary Tata Power International Pte Ltd, has signed an agreement with Clean Energy AS (Clean Energy) and IFC InfraVentures (IFC) for developing hydro projects of an aggregate capacity of 400 MW in Georgia. The Company is also looking at other opportunities to bid in the near future.
Harnessing Solar Energy: Tata Power has a strong portfolio of 60 MW of solar generation capacity. It commissioned its solar power project of 25 MW in Mithapur, Gujarat in January 2012 and a 28.8 MW solar power project in Palaswadi, Maharashtra in May 2014. It has also executed a 3 MW solar photo-voltaic plant at Mulshi, one of the largest grid-connected solar projects in the State of Maharashtra. The Company had set up its first solar power plant of 110 kW, way back in 1996 at Walwhan in Lonavla. A 60.48 kWp solar power plant has been installed on the rooftop of one of the Company’s offices in Mumbai in 2010 and the power generated by these solar panels takes part of the lighting load of the entire building.
Harnessing Wind Energy: Tata Power has an installed capacity of 868 MW and plants spread across five states of Maharashtra, Gujarat, Tamil Nadu, Karnataka and Rajasthan the leading states in promoting wind power generation in India. Cennergi is a Joint Venture (JV) between Tata Power and Exxaro Resources, a South Africa-based diversified resources company. Based in South Africa, Cennergi will focus on the investigation of electricity generation projects in South Africa, Botswana and Namibia. The initial project pipeline focuses on renewable energy projects in South Africa and Cennergi’s strategy is to create a balanced portfolio of generation assets. Cennergi Pty. Ltd. the Company’s JV in South Africa, Cennergi (Proprietary) Limited, achieved financial closure of 134.4 MW Amakhala Emoyeni Wind Farm and 95.17 MW Tsitsikamma. Community Wind Farm in May 2013 and June 2013 respectively. The construction of both projects is progressing on schedule.
Exploring Geothermal Power : 240 MW Sorik Marapi Geothermal Project: A consortium led by Tata Power along with Origin Energy Ltd., Australia and PT Supraco, Indonesia won the Sorik Marapi geothermal project in Northern Sumatra, Indonesia. The project is in the exploration phase. SMGP executed Power Purchase Agreement with PT.PLN (Indonesia State Power Off-taker) on 29th August 2014. Key contracts for drilling and related infrastructure support has been awarded.
Waste Gas Generation: Tata Power has set up various plants at Haldia and in Jamshedpur (Power 6) based on the blast furnace and coke oven gases which are waste gases from steel making process which help in reducing greenhouse gas emission significantly. It's looking at other similar projects with Tata Steel.
Focus on Clean technologies: Tata Power is experimenting with span of unique pilot projects across energy sources:
- Biomass gasification: An 8 to 14 kW biomass producer gas based generation system has been developed with the help of Tata Motors and IISc. A pilot plant is being commissioned at Walwhan. The gasifier for the same has been designed in-house and is under fabrication
- Concentrated photovoltaic (C-PV): A 13.5kW pilot unit was developed in which sunrays are concentrated on PV cells and the assembly floats on Walwhan lake (Maharashtra) in order to cool the cells. The pilot project is currently under evaluation
- Solar powered telecom towers: More than 600,000 telecom towers in India use diesel generator sets to provide power to their antennas. Tata Power Solar Solutions Ltd., a 100% subsidiary of Tata Power is providing solar PV panels that can replace the gensets on 25 such installations. This technology can be upgraded to augment power to local grids. Tata Power has successfully demonstrated similar generation solution, using thin film technology which overcomes the effect of shadows from the tower
