Sterling and Wilson Renewable Energy Limited has informed the stock exchanges that its step-down material subsidiary, Sterling and Wilson Solar Australia Pty Ltd (SWSAPL), has initiated arbitration proceedings against Shell New Energies Australia Pty Ltd over disputes related to the Gangarri Solar Farm in Queensland, Australia.
According to the company’s regulatory filing, SWSAPL submitted a Request for Arbitration under the London Court of International Arbitration (LCIA) Rules 2020 on July 14, 2026. The filing seeks the constitution of an arbitral tribunal to resolve the commercial dispute. Sterling and Wilson Renewable Energy disclosed the development to BSE Limited and the National Stock Exchange of India Limited on July 15, 2026, in compliance with Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations.
The dispute arises from two contracts signed for the Gangarri Solar Farm project. Under these agreements, Shell New Energies Australia acted as the project owner, while SWSAPL was appointed as the contractor. One contract relates to the Engineering, Procurement and Construction (EPC) of the solar power project, while the second covers the Operations and Maintenance (O&M) services for the facility.
As part of the arbitration, SWSAPL is seeking financial compensation for alleged damages under two possible operating scenarios for the project. In the first scenario, based on the solar farm operating at its full 120 MW capacity with harmonic filters installed, the company is claiming AUD 28,029,620.50 and USD 1,638,628.
In the second scenario, which assumes the plant operates at a reduced capacity of 95 MW without harmonic filters, SWSAPL is seeking AUD 20,604,122.57 along with USD 1,638,628.
The company has stated that, under both scenarios, it is also requesting any other amount that the arbitral tribunal considers appropriate, together with applicable interest and reimbursement of legal costs incurred during the proceedings.
The regulatory filing was signed by the Company Secretary and Compliance Officer of Sterling and Wilson Renewable Energy Limited.
