National Grid Saudi Arabia, a wholly-owned subsidiary of Saudi Electricity Company (SEC), has awarded the local Alfanar Company an engineering, procurement and construction (EPC) contract for five battery energy storage system (bess)  facilities with a total combined installed capacity of up to 2,500MW, equivalent to about 10,000 megawatt-hours (MWh).

China's BYD Auto won the contract for the design; supply; supervision of installation, testing and commissioning; and maintenance of the bess plants.

MEED previously reported that the planned facilities, each with a capacity of 500MW or about 2,000MWh, are located in – or in proximity to – the following cities and load centres:

  • Riyadh
  • Qaisumah
  • Dawadmi
  • Al-Jouf
  • Rabigh

The EPC contract value is over $2bn, according to estimates from regional projects tracker MEED Projects.

The scope includes the construction of bess substations and associated infrastructure.

The main applications for the planned bess facilities include load shifting, black start, frequency regulation and voltage support.

They are expected to replace part-load operation of existing power plants by charging and discharging electricity according to system load variations and primary and secondary reserves, among other potential applications.

In August last year, National Grid Saudi Arabia awarded the EPC contracts for three energy storage systems to Riyadh-based investment group Algihaz Holding.

The projects are located in Najran, Madaya and Khamis Mushait.

According to an industry source, the contracts are valued at more than $800m.

Surging growth

The overall capacity of deployed bess facilities globally is expected to reach 127GW by 2027, up from an estimated cumulative deployment of 36.7GW at the end of 2023, according to GlobalData.

The global information services provider named Chinese companies BYD and CATL and South Korean companies LG Energy Solutions and Samsung SDI among the top battery technology providers globally.

Carmakers Tesla, Volkswagen, Stellantis, General Motors, Mitsubishi Motors and Hyundai were identified as the key end-markets for battery products to date.

GlobalData expects battery energy storage deployment to increase “due to a large number of countries opting for battery storage systems to enhance their power sector transformation”.
