Amiral CHP power generation Project, Saudi Arabia

Amiral CHP power generation Project, Saudi Arabia

The Amiral Project, located in Jubail, Saudi Arabia, is a state-of-the-art petrochemical complex being developed and operated by the SATORP joint venture, owned by Saudi Aramco (62.5%) and TotalEnergies (37.5%). The integrated SATORP refinery is a core $11 billion project underscoring Saudi Arabia’s commitment to innovation in energy development.

Abu Dhabi National Energy Company PJSC (TAQA), together with JERA Co., Inc (JERA), will be developing, owning, financing and operating a new industrial steam (452 tonnes per hour (TPH)) and electricity (475MW) cogeneration plant that will produce electricity and steam for the Amiral petrochemical complex located in Jubail in the Eastern Province of the Kingdom.   

Tribe Infrastructure Group (Tribe) served as the sole financial advisor to the consortium of TAQA (51%) and JERA (49%). The project is a critical component of the overall development, providing energy-efficient and reliable power and heat to support the operations of the petrochemical facility.

CHP, also known as cogeneration, is an energy-efficient system that simultaneously generates electricity and useful heat from the same energy source. By capturing and utilising the heat produced during electricity generation, CHP systems significantly enhance overall energy efficiency, supporting industrial operations with both power and thermal energy while reducing waste.

Construction of the CHP facility commenced in 2024, with commercial operations planned for 2027.

Noteworthy is the specific project-on-project structure whereby SATORP, as offtaker to the CHP project, is itself a project financed vehicle developing and operating the wider refinery activities. This has required a specific risk allocation and security package in order to enable project bankability at competitive financing terms.


Tribe’s Role

Tribe played a pivotal role in supporting the consortium’s successful financing structuring and implementation, with responsibilities spanning financing structuring, negotiation of financing agreements & terms, financial modelling, advice on bankability of project agreements, hedging structuring and implementation.

Financing Structuring

Tribe led the sourcing, structuring and negotiation of long term non-recourse debt arrangements including senior debt, working capital facility and VAT facility, through building of the bank group while optimising financing terms beneficial for the overall tariff competitiveness.

Negotiation of Financing Agreements

Tribe led the negotiation of the different Islamic finance-based project facilities with the support of the Sponsors/Lenders Legal Advisors, including execution of Istisna/Ijara senior debt, Murabaha VAT facility and developing working capital facility detailed termsheet.

Financial Modelling

Tribe developed and maintained a tailored financial model to meet tender and sponsor/procurer post-bid requirements up to financial close. This included conducting suites of sensitivity for the lenders and optimisation analyses for post bid sponsors negotiation with SATORP. Tribe also managed the financial model audit process as well as implementation of tax and accounting recommendations for other advisors. 

Bankability of Project Agreements

Tribe acted as bridge between lenders and sponsors/SATORP during the negotiation of the final project agreements (power/steam offtake, EPC, O&M, wider security package) to ensure full bankability of the transaction, based on evolution of recent Aramco precedents for non-recourse project debt while adapting to the specific requirements due to the project-on-project deal structure.

Hedging

Tribe developed and implemented the USD SOFR hedging for the project, from negotiation with and alignment from MLA’s hedging participation to implementation and execution of interest rate SWAPs at financial close with market counterparties through market rate live competitive tender.


Pete McCreanor, CEO, Tribe Infrastructure Group
“Our role in advising the consortium bidding for the Amiral CHP project reflects our expertise in delivering robust, tailored solutions for complex infrastructure bids. By integrating advanced financial modelling, risk-balanced advisory, and strategic project structuring, we ensured that the consortium presented a highly competitive bid aligned with Aramco’s technical and financial requirements.”

Nicolas Jarrosson, Director, Tribe Infrastructure Group
“Tribe’s involvement in the Amiral CHP bid underscores our ability to navigate intricate financial and technical landscapes, providing the consortium with a comprehensive financing solution for success. From optimising financial financing strategies to delivering execution of financing agreements and hedging implementation, we worked closely with all stakeholders to meet the stringent requirements of a project that is integral to Saudi Arabia’s energy transition and industrial growth under Vision 2030.”


Summary

By delivering advanced full-fledged financial advisory services, Tribe ensured a competitive and bankable successful financial closing. This reflects Tribe’s expertise in enabling innovative, sustainable energy solutions for complex infrastructure projects.

Abu Dhabi Waste-to-Energy Initiative

Abu Dhabi Waste-to-Energy Initiative

Located near the Al Dhafra landfill, the $600 million facility will process 900,000 tonnes of municipal solid waste annually, generating 80 MW of electricity—enough to power 52,500 households. By reducing carbon emissions by 1.1 million tonnes annually (equivalent to removing 240,000 cars from the road), the project significantly contributes to the UAE’s goal of diverting 75% of waste from landfills.

The facility will be developed, financed, constructed, operated, and maintained by a consortium comprising Japan’s Marubeni Corporation, Switzerland’s Hitachi Zosen Inova (HZI), the Japan Overseas Infrastructure Investment Corporation (JOIN) and Tadweer.

Construction is expected to take three years, with commercial operations commencing in 2027 under a 30-year concession agreement.


Tribe Advisory’s Role

Tribe Advisory served as the lead and financial advisor to EWEC and Tadweer, guiding the project from inception to financial close over three years. As the first WtE project procured under the EWEC model and the first of its kind in Abu Dhabi, the facility represents a significant milestone in the region’s sustainability efforts.

Tribe’s role encompassed the entire project lifecycle, including business case development, stakeholder alignment, regulatory navigation, project structuring and financial feasibility, tender development and implementation. This marks Tribe’s third successful WtE transaction in the GCC, following on from Dubai and Sharjah,  further solidifying its position as a leader in the sector.

Key contributions included:

  • Business Case Development and Approvals:
    • Developed the initial business case and secured government approvals to advance the project.
  • Procurement Management:
    • Directed the procurement process using the principles of Abu Dhabi’s Law No. 2 of 1998 (IPP Law), successfully adapting it for the WtE sector.
    • In partnership with Ashurst, acting as legal advisor to the procurer, Tribe developed a bespoke ‘first of a kind’ contracting structure, whereby Tadweer and EWEC act as joint procurer, both entering into the Concession Agreement (on a joint and several basis) with the Project Company
    • Managed the tendering process, including engagement with Developers and Investors.
  • Stakeholder Coordination:
    • Facilitated collaboration between EWEC, Tadweer, Transco, EAD, ADEO, Department of Finance and numerous bidding consortium, ensuring alignment with Abu Dhabi’s sustainability objectives.
  • Award and Financial Close:
    • Oversaw the bid assessment and award process, culminating in a successful financial close in July 2024.
    • Secured investment for the project through a joint venture comprising Marubeni, HZI, and JOIN, with Tadweer holding a 60% government stake.
