What we do
Today ACWA Power is an acknowledged leader in energy transition, the largest private water desalination company in the world (by gross capacity), and first mover in green hydrogen. We make energy and water more affordable and accessible.
The Company has four areas of operation.
How it works
Photovoltaic (PV) generates power through the photovoltaic effect whereby electricity is generated when the concentrated light is converted to heat, which drives a steam turbine connected to an electrical power generator. Wind power uses turbines to mechanically power generators for electricity.
CSP concentrates the sun’s energy onto a receiver at the top of a tower using sun‑tracking mirrors (known as heliostats) heating up a fluid which drives a steam turbine connected to an electrical power generator.
Battery Energy Storage Systems (BESS) are rechargeable batteries that can store energy from different sources and discharge it when needed.
ACWA Power’s position in these technologies
ACWA Power plans to achieve net zero by 2050 and be a key enabler of the decarbonisation strategy for the Kingdom and the countries where we operate. Over the past decade, ACWA Power has reduced the solar PV tariff by more than 80% and the Concentrated Solar Power (CSP) tariff by more than 60%.
Energy storage is a vital solution, giving flexibility to renewable power generation and making it more sustainable. Storage is deployed in our projects in the form of BESS or CSP technology. Today our portfolio includes the larget single‑site CSP and off‑grid BESS facilities in the world.
Current portfolio
How it works
Reverse Osmosis (RO) is an energy‑efficient process for sea water desalination and uses semi‑permeable membranes and pressure to separate salts from water. Thermal desalination is the process of boiling water, using a vacuum distillatory, at less than atmospheric pressure.
ACWA Power’s position in these technologies
ACWA Power is the largest private water desalinator in the world and has the largest SWRO plants in the world, the largest hybrid solar PV SWRO plant and the first, and only, 100% green SWRO plant in the world.
ACWA Power has shifted from thermal desalination to SWRO, reduced the water tariffs by 58% and reduced the Specific Power Consumption required to desalinate per m3 of water by 87% in a decade.
Current portfolio
How it works
Green hydrogen and its derivatives are the new renewables. The electrolysis process passes a strong electrical current through a tank of water (H2O), to split the molecules into its two constituent elements, and then converts the hydrogen into ammonia for ease of transport.
ACWA Power’s position in these technologies
ACWA Power is first mover in at‑scale green hydrogen and is constructing the world’s biggest green hydrogen project in the NEOM region. This makes us, along with our partners, the largest player in green ammonia, with the NEOM Green Hydrogen Project and our second project in Uzbekistan, catering to fertilisers locally and for export in the future. Several MoUs have been signed to develop green hydrogen projects in Indonesia, Thailand, Egypt, and Uzbekistan.
Current portfolio
223,000 million tonnes/year of GH2
How it works
Gas power plants produce less emissions compared to oil or coal and use turbines to ignite gas to produce combustible gases to power generators.
ACWA Power’s position in these technologies
Flexible generation currently in our portfolio is largely represented by Combined Cycle Gas Turbine (CCGT) assets and will remain a viable technology alternative in emerging markets given the growth prospects in these economies. We currently have four Heavy Fuel Oil (HFO) assets, one of which is being converted to an SWRO desalination plant. We are exploring various options with offtakers for the three other assets to make them more efficient, with less emissions.
