Saudi Arabia Solar Projects

Saudi Arabia is developing one of the world’s most ambitious solar energy programmes, with a pipeline exceeding 40 GW of planned capacity as part of the National Renewable Energy Programme (NREP). The Kingdom’s exceptional solar irradiance, with annual averages exceeding 2,200 kilowatt-hours per square meter, combined with vast available land and strong government commitment, positions Saudi Arabia as a future global leader in solar power generation under Vision 2030.

The National Renewable Energy Programme

The NREP, administered by the Ministry of Energy in coordination with the Renewable Energy Project Development Office (REPDO), targets 50 percent of electricity generation from renewable sources by 2030. Solar photovoltaic (PV) and concentrated solar power (CSP) constitute the majority of this target, supplemented by wind power.

The programme procures renewable energy capacity through competitive reverse auctions that have achieved record-low tariffs globally. The first rounds of NREP tenders in 2018-2019 attracted bids as low as USD 0.0169 per kilowatt-hour for solar PV, among the cheapest electricity ever contracted anywhere in the world at the time.

Major Solar Projects

The Sudair Solar Plant, at 1.5 GW, is the largest single-site solar PV project in Saudi Arabia and one of the largest globally. Developed by ACWA Power in partnership with PIF’s Badeel subsidiary, the plant generates enough electricity to power approximately 185,000 homes and displaces significant volumes of natural gas previously used in power generation.

The Shuaibah Solar Project (2.6 GW combined phases) in the Makkah Province represents another massive solar development. The Al Faisaliah Solar Project in the Makkah region and the Ar Rass Solar Project in the Qassim region add multi-hundred-megawatt capacity to the growing fleet.

The Sakaka Solar Plant (300 MW), the first utility-scale renewable energy project in the Kingdom, commenced operations in 2021 and served as a proof of concept for the NREP programme.

ACWA Power’s Role

ACWA Power, the Saudi-listed renewable energy developer, is the primary vehicle for the Kingdom’s solar ambitions. The company develops, invests in, and operates solar plants under long-term power purchase agreements with the Saudi Power Procurement Company (SPPC). ACWA Power’s Saudi solar portfolio exceeds 10 GW of capacity in various stages of development and operation.

PIF holds a significant stake in ACWA Power and supports the company’s growth through co-investment in major projects. The company’s international portfolio across the Middle East, Africa, and Central Asia provides technology and operational expertise that benefits its Saudi projects.

Technology and Innovation

Saudi solar projects employ both utility-scale PV and, in some cases, concentrated solar power with thermal storage. PV technology dominates due to its rapidly declining costs and proven reliability. Bifacial solar panels, which capture reflected light from both sides, are increasingly deployed in Saudi desert environments where ground reflection enhances output.

Battery energy storage systems (BESS) are being integrated with new solar projects to provide dispatchable power and grid stability. The combination of solar PV with 4 to 6 hours of battery storage creates a generation profile that can serve evening peak demand, addressing one of solar energy’s traditional limitations.

Research and development in solar technology is supported by institutions including the King Abdullah University of Science and Technology (KAUST), which conducts research into next-generation PV materials, solar desalination, and concentrated solar applications.

Grid Integration

The Saudi Electricity Company (SEC) is upgrading the national grid to accommodate the growing share of renewable generation. Transmission infrastructure connecting solar plants in remote areas to demand centers in Riyadh, Jeddah, and the Eastern Province requires significant investment. Smart grid technologies, demand-side management, and grid-scale storage are being deployed to maintain system reliability.

Economic and Environmental Impact

The solar programme generates economic value through construction employment, equipment manufacturing (with increasing local content requirements), and operation and maintenance jobs. Tariffs achieved through competitive bidding make solar power the cheapest source of new electricity in the Kingdom, reducing the subsidy burden on government finances.

Environmentally, the solar programme supports Saudi Arabia’s commitment under the Saudi Green Initiative to reach net-zero greenhouse gas emissions by 2060. Each GW of solar capacity displaces approximately 1.5 to 2 million tonnes of CO2 annually by replacing gas-fired generation.

Investment Opportunities

The solar pipeline creates opportunities for equipment suppliers, EPC contractors, financing providers, and technology companies. The scale of procurement, with tens of billions of dollars in capital deployment expected through 2030, makes the Saudi solar market one of the most significant globally for renewable energy investors and service providers.
