Oman opens bids for 1GW battery storage advisory role

4 June 2026

Oman’s Authority for Public Services Regulation (APSR) has opened technical bids for a consultancy contract supporting a planned 1,000MW/four-hour battery energy storage system (bess) project.

The tender seeks independent regulatory, technical and commercial validation services for the scheme. The project is planned with a rated capacity of 1,000MW and a storage duration of four hours, equivalent to 4,000 megawatt-hours (MWh) of energy storage.

According to a tender board notice, technical bids were opened on 25 May.

Thirteen companies submitted proposals including:

  • Tractebel Engineering Consultancy (Belgium)
  • WSP International (Canada)
  • CESI Middle East (Italy)
  • DNV Dubai Branch (Norway)
  • ILF Consulting Engineers (Austria)
  • Mott MacDonald (UK)
  • Innovision Engineering Consultancy (UAE) 
  • Sargent & Lundy Abu Dhabi (US)
  • Universal Consulting Engineering (Egypt)
  • TUV Rheinland (Germany)
  • Surbana Consultants Dubai Branch (Singapore)
  • Afry Management Consulting (Sweden)
  • Engineering Systems Group (Kuwait)

As previously reported, APSR issued the request for proposals in April as part of wider plans to increase the share of renewable energy in the sultanate.

The sultanate’s first utility-scale solar photovoltaic (PV) plant integrated with battery energy storage (Ibri 3) entered construction at the beginning of the year, comprising a 500MW solar PV plant and a 100MWh bess system.

Last month, state offtaker Nama Power & Water Procurement Company signed a power-purchase agreement with local firm O-Green for Oman’s first round-the-clock renewable energy project.

The company is also seeking consultants to provide separate environmental, social and governance and legal advisory services.

Renewable energy is expected to increase from 4% of the generation mix in 2024 to 30% by 2030, driving the push for more utility-scale storage projects.

Over roughly the same period, demand is forecast to double, reaching 10 terawatt-hours by 2031.
