GE steam turbines to boost output, efficiency of Saudi Arabian power plant

Riyadh, Saudi Arabia, May 17, 2010 — GE has received a contract of nearly $300 million to supply five steam turbines for an expansion of the Saudi Electricity Co.’s Qurayyah Open Cycle Power Plant in Saudi Arabia.

The five steam turbines will join 15 GE F-technology gas turbines already operating at the site, converting the plant to combined-cycle operation to help Saudi Arabia meet its goals for greater power generation capacity and efficiency.

When the power plant conversion is completed, scheduled for the second quarter of 2012, the site’s power output will increase from 1,907 to 3,148 MW — a boost of 1,241 MW, equivalent to 10 percent of the SEC installed capacity in the Eastern Province. This will help meet the growing industrial and residential power demand in the Kingdom’s eastern and central regions.

“One of our central priorities is to increase the efficiency of our power production, within the context of increasing our electricity output to meet the Kingdom’s growing power needs,” said Eng. Ali Saleh al-Barrak, president and CEO of Saudi Electricity Company. “Converting the Qurayyah plant to combined-cycle operation will allow us to produce more power from the same amount of natural gas, which also helps meet our environmental requirements.”

With its rapidly growing population and economic development, Saudi Arabia’s demand for electricity has been increasing at a rate of 8 percent or more a year. Saudi Arabia’s Industry and Electricity Ministry estimates that the Kingdom will require up to 20 GW of additional power-generating capacity by 2019.

When the Qurayyah plant conversion is completed, the combined-cycle facility will include five GE 307FA combined-cycle packages; each featuring three Frame 7FA gas turbines and one GE D Series steam turbine.

In a combined-cycle configuration, exhaust gas from a gas turbine-generator is converted to steam, which is used to drive a steam turbine-generator, enabling the plant to produce additional power without an increase in fuel consumption.

The increased fuel efficiency of combined-cycle technology means that less carbon dioxide is produced per megawatt of power generated.

The engineering and procurement company contract for the plant expansion was secured by the Arabian Bemco Contracting Co. and South Korea’s Doosan Heavy Industries.
