Maharashtra is one of the most industrialised and urbanised states in the country. The state’s power sector has made substantial progress over the past decade with an increase in generation capacity and strengthening of the network infrastructure leading to an improvement in the power supply position. As per the national power portal, Maharashtra has a total thermal power capacity of 27,063.08 MW as of September 2022, of which approximately 23,856 MW comes from coal and the remaining 3,207 MW from gas. The fleet of coal-fired power plants in Maharashtra is among the largest in the country, comprising 56 per cent of the total power generation capacity.
Meanwhile, according to the Ministry of New and Renewable Energy, the state’s total installed renewable power capacity is 11,421.96 MW (as of September 2022). At 5,012.83 MW, the installed wind power capacity accounts for more than 50 per cent of the total renewable capacity in the state. Solar power has the second-highest installed capacity among renewables, at 3,391.63 MW. This comprises ground-mounted projects (2,089.10 MW), rooftop projects (1,202.44 MW) and offgrid projects (100.09 MW). Bioenergy ranks third, with a total installed capacity of 2,636.42 MW. Of this, biomass power (bagasse cogeneration), biomass cogeneration (non-bagasse), waste-to-energy (WtE) and WtE-offgrid account for 2,568 MW, 16.4 MW, 12.59 MW and 39.43 MW respectively. The remaining 381.08 MW is small-hydro capacity. Renewable Watch takes a look at recent developments, tenders, auctions and policies in Maharashtra…
Recent projects and tenders

MAHAGENCO also invited bids to select a power developer to set up a 150 MW grid-connected floating solar project at the Erai Dam solar park in the Chandrapur district of Maharashtra. In the same month, Mahatma Phule Renewable Energy and Infrastructure Technology invited bids to set up a 1 MW green hydrogen plant with the associated ecosystem on a build-own-and-operate basis in Maharashtra.
May 2022: MSEDCL invited a request for proposal for the procurement of 325 MW of wind power on a long-term basis through a competitive bidding process (followed by reverse e-auction) from intra-state wind power projects. The Maharashtra energy department and ReNew Power also signed an agreement of Rs 500 billion for renewable energy projects in the state over the next six to seven years. In the same month, MSEDCL invited bids to procure 431 MW of solar power from decentralised solar projects of 500 kW to 2 MW capacity under Component A of the PM-KUSUM scheme in Maharashtra.

Prior to this, Indian Renewable Energy Development Agency authorised Rs 144.45 billion in loans and distributed Rs 100.18 billion to various green energy projects across the state.
February 2022: MSEDCL invited bids to procure 445 MW (AC) of power from decentralised solar projects of 500 kW to 2 MW capacity under Component A of the PM-KUSUM scheme in the state.
January 2022: Bharti Airtel announced commissioning of a 21 MW solar power plant in Bhuldana district of Maharashtra.
Auction activity
The past few months have been quite eventful in Maharashtra’s renewable energy space, owing to a series of successful tender auctions, which resulted in the discovery of competitive tariffs. In September 2022, NTPC Renewable Energy Limited and Avaada Energy were declared winners in MSEDCL’s auction to procure power from 500 MW of grid-connected inter- or intra-state solar projects (Phase VIII) on a long-term basis. NTPC won 200 MW by quoting Rs 2.82 per kWh. Avaada Energy quoted Rs 2.83 per kWh for 500 MW but was awarded 300 MW under the bucket filling method.
In July 2022, SJVN Green Energy, Juniper Green Energy, TPREL, SAEL (Sukhbir Agro Energy Limited) and Avaada Energy were declared winners in MSEDCL’s auction to procure power from 500 MW of grid-connected intra-state solar projects (Phase VII) on a long-term basis. SJVN and Juniper won 200 MW and 75 MW capacity, respectively, with each quoting Rs 2.90 per kWh. Tata Power and SAEL won capacity of 150 MW and 50 MW respectively, with each quoting Rs 2.91 per kWh. Avaada quoted Rs 2.91 per kWh for 300 MW, but was only awarded 25 MW under the bucket filling method.
Policy impetus
In order to increase the amount of accessible power and reduce power purchase costs in the future, Maharashtra has launched an ambitious plan to build additional solar plants throughout the state to produce 12 GW of renewable energy over the next six years. In January 2021, the Maharashtra state cabinet issued its Unconventional Energy Generation Policy to promote non-conventional source-based energy generation. According to the state’s unconventional energy generation policy, Maharashtra intends to continue on its leadership track and generate 40 per cent of its electricity from renewable sources by 2030. The policy is divided into two parts. In the first part of the policy, the state seeks to implement 17.36 GW of transmission system-connected renewable power projects by 2025. This includes 12.93 GW of solar projects, 2.5 GW of wind energy projects, 1.35 GW of cogeneration projects, 380 MW of small-hydro projects and 200 MW of urban solid waste-based projects. The 12.93 GW of solar projects include 10 GW of stand-alone solar power projects, 2 GW of grid-connected rooftop solar projects, 500 MW of solar-based water supply projects and 250 MW of solar generation projects for farmers, among others. Under the second part of the policy, the state plans to implement over Rs 780 million worth of transmission-free projects. These include 100,000 agricultural solar pumps, 52,000 kV of rooftop solar systems, 2,000 solar water supply stations, electrification of 10,000 rural homes, microgrid projects for 20 homes, 55,000 square feet of solar water/solar cooking systems and 800 solar cold storage projects.
In July 2021, the state government also announced the Draft Electric Vehicle Policy. The policy aims to support the adoption of sustainable and clean mobility solutions in Maharashtra. The primary objective of the draft policy is to accelerate the adoption of electric vehicles in the state so that they can contribute to 10 per cent of the new vehicle registrations by 2025.
The way forward
The present thermal-dominated generation mix in the state is unsustainable, both environmentally and economically. Coal-based power plants not only release greenhouse gases but the power generation is also water intensive. Concerted efforts are needed by the state government and developers to promote renewable energy development and achieve the set targets.
Maharashtra has been making steady progress in the clean energy transition by promoting utility-scale solar and solar-wind projects as well as decentralised solar projects such as solar pumps, solar agricultural feeders and solarisation of diesel pumps. However, going forward, more efforts need to be made in this space to meet the planned solar targets in the state. In addition, a favourable regulatory environment for open access and rooftop solar projects will go a long way in facilitating the energy transition in the state.
