Abu Dhabi Future Energy Company (Masdar) has reached financial close on the world's first gigascale round-the-clock (RTC) renewable energy project, securing a $5.1bn financing package from a consortium of 13 international and local banks.

The project, being developed in Abu Dhabi with state offtaker Emirates Water & Electricity Company (Ewec), represents a total capital investment of $6.1bn, with Masdar providing $1bn of equity. It integrates a 5.2GW solar photovoltaic (PV) plant with a 19GWh battery energy storage system (bess), which Masdar says is the largest system of its kind in the world.

The 13 lenders providing the financing are Abu Dhabi Commercial Bank, Abu Dhabi Islamic Bank, France's BNP Paribas, Bank of China, France's Credit Agricole Corporate & Investment Bank, Dubai Islamic Bank, First Abu Dhabi Bank, UK-based HSBC, Germany's KfW Ipex-Bank, France's Natixis, Japan's Sumitomo Mitsui Banking Corporation, UK-based Standard Chartered Bank and France's Societe Generale.

The independent power project (IPP) is designed to deliver 1GW of baseload power around the clock, addressing the challenge of solar intermittency by pairing large-scale generation with battery storage. It is intended to serve large energy users requiring 24/7 clean electricity, including data centre operators and technology firms driving artificial intelligence deployment in the region.

Ewec will act as offtaker under a long-term power purchase agreement, while private offtakers such as data centres will access electricity through back-to-back arrangements.

India's Larsen & Toubro and Beijing-headquartered PowerChina are handling engineering, procurement and construction (EPC) works, with PwC Middle East advising Ewec on financial structuring. China's CATL will supply the battery storage system, while Jinko Solar and JA Solar will each provide 2.6GW of PV modules.

Masdar broke ground on the project in October 2025, and it is expected to be operational in 2027. The scheme will avoid 5.7 million tonnes of carbon dioxide emissions a year and provide enough clean energy to power nearly half a million homes.

The developer has a diversified portfolio of more than 65GW and has set a target of reaching 100GW of renewable energy capacity by 2030.
