Tata Power has 5.1 GW renewable projects under construction

Tata Power reported 5.1 gigawatts (GW) of renewable projects under construction in Q2 FY27, with 87% of its renewable pipeline tied to long-term power purchase agreements (PPAs). Its five named projects combine firm and dispatchable renewable energy (FDRE), hybrid and RTC contracts, with 1,228 megawatts (MW) of PPA capacity and 2,919 MW of installed capacity.

How large is Tata Power’s renewable construction pipeline?

Tata Power’s renewable projects under construction total 5.1 GW, compared with installed capacity of 17.4 GW at Q2 FY27. The capacity-additions chart shows 22.5 GW for FY 2028e, with the “e” denoting the company’s estimate, before separately listed hydroelectric and pumped-storage projects take the total shown to 27.1 GW.

The 17.4 GW installed base includes 8.8 GW of thermal capacity, 0.9 GW of hydro, 5.8 GW of solar, 1.3 GW of wind and 0.6 GW of waste-heat recovery systems. Solar and wind together account for 7.1 GW, while the 5.1 GW construction programme is identified specifically as renewable-energy projects.

Tata Power lists 1.0 GW Bhivpuri, 0.6 GW Khorluchu, 1.1 GW Dorjilung and 1.8 GW Shirwata beyond the FY 2028e capacity figure. These four hydroelectric and pumped-storage projects add 4.5 GW to the 22.5 GW figure, producing the 27.1 GW total displayed in the presentation.

Which contracts make up Tata Power’s construction portfolio?

Tata Power’s five named awards comprise three FDRE projects, one hybrid project and one RTC project. Their PPA capacities add to 1,228 MW, while their installed capacities total 2,919 MW because the FDRE and RTC projects are generally sized at about three times their PPA capacity and the hybrid project at about 1.3 times.

The FDRE contracts are the 460 MW SJVN project, 200 MW NTPC project and 80 MW Tata Power Mumbai DISCOM project, together representing 740 MW of PPA capacity. Their tariffs are Rs 4.38, Rs 4.71 and Rs 4.77 per unit, respectively, and each is shown with capacity sizing of about three times.

The 400 MW MSEDCL Phase IV hybrid project has the lowest listed tariff, at Rs 3.60 per unit, and its 501 MW installed capacity is about 1.3 times its PPA capacity. By comparison, the 88 MW SJVN RTC project has the highest tariff at Rs 4.91 per unit and 272 MW of installed capacity, or about three times its contracted capacity.

What is the PPA and commissioning position for Tata Power’s projects?

Tata Power had received Letters of Award (LoAs) for all five named projects, while four PPAs were signed as presented. The 88 MW SJVN RTC project was the exception: its LoA had been received, but its PPA remained pending and its expected commissioning was stated as 24 months after PPA signing.

Phase-wise commissioning had started in FY 2027 for the SJVN 460 MW FDRE project. Tata Power shows the 400 MW MSEDCL Phase IV hybrid project for FY 2027, while the 200 MW NTPC FDRE project and 80 MW Tata Power Mumbai DISCOM FDRE project are expected in FY 2028.

The five electronic reverse auction dates range from 7 November 2023 to 19 August 2025. SJVN’s 460 MW FDRE project was auctioned on 7 November 2023, NTPC’s 200 MW FDRE project on 22 March 2024, MSEDCL’s hybrid project on 16 August 2024, SJVN RTC on 27 February 2025 and Tata Power Mumbai DISCOM’s FDRE project on 19 August 2025.

Tata Power says 87% of its wider renewable pipeline is tied to long-term PPAs. That figure applies to the pipeline rather than solely to the five projects listed in the project table, which shows four signed PPAs and one pending agreement.

What execution measures does Tata Power disclose for renewable additions?

Tata Power says land acquisition remains aligned with execution for its renewable programme and that it is creating a large land bank to support future capacity additions. It also says transmission connectivity has been secured for renewable projects under construction, covering two development requirements for the 5.1 GW programme.

A 101.2 megawatt-hour BESS received COD on 8 October 2026. Tata Power’s capacity-additions chart also marks 0.2 GW with that BESS note, although the storage asset itself is presented in megawatt-hours rather than a matching generation-capacity measure.

Tata Power also states that most of its under-construction solar projects can use ALMM modules. Its solar manufacturing plant produced 1,000 MW of modules and 906 MW of cells in Q2 FY27, compared with 1,001 MW of modules and 862 MW of cells in Q1 FY27.

Conclusion

Tata Power’s disclosed renewable programme combines 5.1 GW under construction with a contract mix led by FDRE, hybrid and RTC projects. The five named awards show 1,228 MW of PPA capacity against 2,919 MW of installed capacity, reflecting the larger capacity sizing used for projects designed to meet their contractual delivery structures.

The next disclosed milestones are FY 2027 commissioning for the SJVN 460 MW FDRE and MSEDCL 400 MW hybrid projects, followed by FY 2028 timing for the NTPC 200 MW and Tata Power Mumbai DISCOM 80 MW FDRE projects. Progress on the pending SJVN RTC PPA, as well as execution of land and transmission arrangements, remains relevant to the stated buildout plan.
