GE Vernova’s Gas Power business has begun the execution of the fuel conversion project for Saudi Electricity Company’s (SEC’s) Power Plant 10 (PP10), in Riyadh, marking a vital step in KSA’s carbon emissions reduction.
By switching the turbines from running on liquid fuels to natural gas, which has the lowest carbon emissions of traditional fossil fuels, the project will enhance the units’ fuel flexibility, efficiency and output.
Built on an area of 5 million sq m outside the capital of Saudi Arabia, PP10 is powered by 40 of GE Vernova’s 7E gas turbines in a combined cycle configuration and is one of the largest combined cycle plants in the world. It can deliver approximately 3.5 gigawatts (GW) of electricity, the equivalent capacity needed to power up to 875,000 homes in Saudi Arabia.
Reducing carbon footprint
“We look forward to working with Alfanar and GE Vernova to convert our power generation assets to natural gas, a lower carbon intensity fuel compared to the crude oil and distillate that currently power the plant,” said Khaled AlGanoon, CEO at SEC. “This project will help us reduce the carbon footprint and emissions of our operations at PP10, in alignment with Saudi Arabia’s goal to generate a balanced mix of electricity from renewable energy and natural gas by 2030.”
Following project completion, each gas turbine’s efficiency is expected to increase, which results in lower consumption and cost of fuel per megawatt hour (MWh) of power generated, and greater electricity output per unit of fuel consumed.
Additionally, the units would be able to deliver more flexible power that can be ramped up or down as and when needed, while benefitting from longer inspection intervals, and longer parts life compared to gas turbines powered by liquid fuels.
Furthermore, existing and future gas power plants can avoid carbon dioxide lock-in by using low or near zero-carbon fuels such as hydrogen, combined with carbon capture technologies, both of which the kingdom is beginning to make significant investments in.
Heavy duty gas turbines
This modernisation will also leverage the expertise and know-how built at GE Saudi Advanced Turbines (GESAT), a joint investment by Dussur and GE Vernova to manufacture heavy duty gas turbines and components in the Kingdom. GESAT is manufacturing gas fuel skids for the project, which consist of control valves, piping, and accessories that help manage the flow and pressure of gas supplied to the turbines.
"This project reflects our commitment to technological innovation, environmental responsibility, and advancing Saudi Arabia's energy sector. We are proud to be at the forefront of the energy transition in the kingdom. This is also a great opportunity to work with GE Vernova and to pave the way for a sustainable energy sector in the kingdom," stated Jamal Wadi, President of Alfanar Projects.
“We are honoured to be part of this project with Alfanar and SEC. With electricity demand being high across the kingdom due to factors like hot and harsh environmental conditions, a growing population, and the concentration of energy-intensive industries such as oil & gas, smelters, and petrochemicals, the availability of firm power on demand is critical in Saudi Arabia.
“Reducing the intensity of carbon emissions from power generation activities in the country is an important part of addressing the climate challenge,” said Joseph Anis, President & CEO of Europe, Middle East & Africa for Gas Power at GE Vernova. “We applaud SEC’s efforts to reduce the carbon emissions of their operations for a more sustainable future.”
The 7E gas turbine is a robust, proven platform that delivers high availability and reliability. It has a large installed base of over 1,150 units globally, with more than 270 turbines located in Saudi Arabia. The successful completion of this project can potentially provide learnings that can be applied to convert other 7E units running on liquid fuels across the kingdom to also operate on lower carbon natural gas.
