Tamil Nadu's Renewable Energy Projects Approved

Tamil Nadu Green Energy Projects Overview

1. Regulatory Approval:

   • Tamil Nadu Green Energy Corporation Ltd (TNGECL) received approval from the Tamil Nadu Electricity Regulatory Commission (TNERC) for several renewable energy projects.

2. Battery Energy Storage Systems (BESS):

   • Capacity: 1500 megawatt-hour (375 MW x 4 hours, with 1.5 full charge-discharge cycles daily).
   • Construction Sites: Development at seven substations, including:
     • 230/110 kV: Palladam, Pudukottai, Thatchankurichi, V Thiruvarur.
     • 400/230/110 kV: Karamadai, Thappagundu, Anaikadavu.
   • Funding Model: State Component of the Viability Gap Funding (VGF) scheme under the Union Ministry of Power.
   • Model: Projects to be developed under "Build-Own-Operate" (BOO) for 15 years.

3. Selection of Developers:

   • TNERC authorized TNGECL to select developers via tariff-based competitive bidding (TBCB) with e-reverse auction.
   • Emphasis on including project bidder experience in the selection criteria.

4. Solar Power Project:

   • TNGECL sought permission for a 30 MW Grid-Connected Solar Photovoltaic Power Project complemented by a 30 MW/90 megawatt-hour battery energy storage system in Karur and Thiruvarur.
   • Proposed adjustments will now call for tenders for two 15 MW/45 MWh blocks, rather than a cumulative 30 MW.

5. Hybrid Renewable Energy Project:

   • TNERC also approved a joint petition by TNPDCL and TNGECL to set up a 34.75 MW hybrid renewable energy project comprising:
     • 18.75 MW wind and 16 MW solar capacity.
     • Locations include Kayathar-I and II, Puliankulam, and Muppandal villages.

Implications:

• These projects align with India's broader clean energy goals and commitments towards increasing the share of renewable energy in the energy mix, and reducing greenhouse gas emissions.
• Encourages investment in renewable energy infrastructure and development in Tamil Nadu.

Conclusion: The approvals signify a commitment to expanding the state's sustainable energy portfolio through innovative projects and collaborative efforts with regulatory bodies.
