GE Reduces Emissions With Mobile Gas Turbines
By Adedapo Adesanya
General Electric (GE) has announced that its mobile gas turbines, typically used for emergency use, cannot only meet the emissions requirements in line with World Bank Standards but even surpass them and meet the most stringent emissions standard requirements.
In the State of California, GE developed an innovative technical solution on four TM2500 aero-derivative gas turbines deployed at the Department of Water Resources (DWR) sites in Yuba City and Roseville. The solution reduced nitrogen oxide (NOx) and carbon monoxide (CO) emissions by over 90 per cent, surpassing World Bank Emissions Standards. It marked the world’s first-of-a-kind solution on a GE mobile TM2500. The technology helped lower emissions while supporting the statewide energy grid during extreme climate-driven events, including drought or wildfires.
Speaking on the advancement, Mr Clive Nickolay, CEO of GE Gas Power’s Aeroderivative business line, said, “GE’s aero-derivative mobile technology, typically used for emergency power, represents a perfect complement to renewable energy and peaking power use cases worldwide.
“We’re excited about GE’s efforts to provide power plant operators with a technical solution that will allow them to quickly install peak power when needed while drastically reducing NOx and CO emissions levels to low single digits.”
The technical solution includes engineering studies for the integration and installation of a Selective Catalytic Reduction (SCR) technology system—a proven and effective solution to limit post-combustion emissions.
The technology works by removing common emissions through a catalytic converter transforming the nitrogen oxides contained in the exhaust gas into water vapour and nitrogen. The new solution unlocks dramatic enhancements to emissions performance while ensuring the TM2500 can provide reliable, affordable, and lower-carbon electricity to the grid.
At Yuba and Roseville, GE worked with the engineering, procurement, and construction company Kiewit Power Constructors Co. to install the world’s first-of-this-kind solution on a GE mobile gas power turbine to solve DWR’s emissions challenge. The emissions control solution includes 11-meter-high modules and a 22-meter-high stack. Each of the four TM2500 can produce up to 34 megawatts (MW) of electricity for a total of 136 MW and is now equipped with a system to reduce pollutants to 2.5 parts per million, the legal limit set by the state of California.
Adding his input, Mr Nosizwe Dlengezele, Regional Sales Executive for GE Gas Power business in Sub-Saharan Africa, said, “Sub-Saharan Africa has one of the world’s fastest-growing populations, and natural gas offers a solution that’s more efficient and flexible to enable the integration of more renewables to the grid and ultimately reduce emissions.
“Our TM2500 aero-derivative gas turbines are installed in countries such as Nigeria, Angola, and Ghana, to provide much-needed power because of its enhanced mobility, easy installation and critical grid backup. It also has lower emissions than diesel generators when operating on gas, and the availability of an SCR solution will now enable our customers to further reduce NOx and CO emissions by 90 per cent.”
A key feature of the TM2500 units is its fast start ability providing full power in five minutes. This provides utilities and grid operators like California Independent System Operator (CAISO) or the Western Area Power Authority (WAPA) the ability to quickly support the grid in case of emergencies or loss of intermittent power.
The quick start capability was successfully put to use when the units were brought online to support a strained statewide energy grid during California’s extreme heat wave on Sept 6, 2022.
GE’s trailer-mounted TM2500 is derived from jet-engine technology powering the world’s airlines and is mounted on a wheeled trailer for ultimate mobility. With more than 20 years of experience and over 300 units installed around the world, GE’s TM2500 is a proven solution for providing a baseload bridge to permanent power installations or for generating backup/peak power in the wake of natural disasters, plant shutdowns, grid instability or in isolated locations.
GE powers plants that deliver flexible, efficient, and reliable power to millions of people around the world. With almost 70 years of presence in Sub-Saharan Africa, GE has been collaborating with energy stakeholders to deploy innovative technologies tailored to respond to the needs of the Sub-Saharan Africa region with reliable baseload and flexible power. GE delivers across the entire energy ecosystem from generation to transmission and distribution, and throughout the region, GE-built technologies are supported by GE local service and maintenance teams working together to help ensure access to reliable and sustainable energy.

The National Economic Council (NEC) has approved a $4.5 billion arrangement for the Nigerian National Petroleum Company (NNPC) Limited aimed at strengthening the country’s external reserves and freeing up funds for infrastructure.
This is part of the refinancing of the $3.3 billion Project Gazelle Pre-Export Finance Facility through a new $4.5 billion facility named “Project Gazelle 2”.
The approval allows NNPC Limited to refinance the outstanding balance of approximately $1.5 billion under the original 2023 facility, while unlocking an additional $3 billion in liquidity to strengthen the country’s external reserves and support ongoing fiscal and infrastructure priorities of the government.
NEC’s approval followed a presentation by the Minister of Finance, Mr Taiwo Oyedele, which was presented by the Chairman of the Council, Vice President Kashim Shettima, underscoring the importance of the project.
NEC observed the significance of unlocking additional liquidity to the federation, among other benefits, pledging its support for the actualisation of the initiative.
The Finance Minister explained that the refinancing has been structured on more favourable terms than the original facility, including a reduction in the volume of pledged crude oil from 90,000 barrels of oil per day to approximately 78,750 barrels of oil per day – a 12.5 per cent reduction.
He noted that under the new arrangement, an additional 11,250 barrels of oil per day for the federation will be released, while there will be a reduction in the pledged crude volumes by the state oil company.
Mr Oyedele added that while accessing additional liquidity on improved terms, the arrangement is freeing up resources for strategic national priorities while strengthening the country’s financing structures.
“The arrangement is freeing up resources for strategic national priorities while strengthening the country’s financing structures,” he said.
VP Shettima called for a responsive, scalable, and data-driven social protection policy to tackle multidimensional poverty in Nigeria.
According to Mr Shettima, government policies are often heard before they are seen, speak through the price of food, condition of hospitals, records in schools, strain on families, the confidence of those who invest their labour in the nation’s future, and, very importantly, the ambitions of state governments.
He implored members of Council to ensure that every decision they make assure the citizens “that their government is paying attention to the pulse of the nation and is resolved to respond with competence, compassion and purpose.”

Members of the public have been invited to submit memoranda and policy proposals on the proposed National Policing Bill.
The Chairman of the Working Group, Mr Femi Gbajabiamila, announced this on Monday after the team’s meeting at the State House in Abuja.
The group, headed by the Chief of Staff to President Bola Tinubu, is calling for input from Nigerians as part of efforts to establish a comprehensive legal and operational framework for state policing.
It is reviewing the Police Act 2020, the Police Service Commission framework, police regulations, and other relevant laws to support the development of an effective, modern policing system.
The proposed framework will set national minimum standards, define state readiness and grant certification, clarify jurisdictional responsibilities, ensure independent oversight, uphold human rights, and guarantee sustainable funding. It would also spell out an orderly transition to a dual-policing structure.
The call for memoranda will run for two weeks, allowing citizens, professionals, civil society, security agencies, state and local governments, academics, and other stakeholders to contribute. Submissions will be reviewed and integrated into the draft bill, which will then be subject to further national consultation before being finalised and sent to the National Assembly.
The Working Group has adopted a seven-week work programme running from July 27 to September 14, 2026. The draft Executive Bill is scheduled for presentation to President Bola Ahmed Tinubu on September 3, 2026, with national consultations to follow before the final approval.
The new National Policing Bill will set out requirements for recruitment, training, oversight, funding, and transition arrangements to ensure credible, effective, and accountable policing nationwide.
“A proposed State Police Service must demonstrate that it has credible arrangements for recruitment, vetting, training, pay, pensions, equipment, custody, complaints, discipline, data, firearms control, independent oversight and financial sustainability before it begins policing,” Mr Gbajabiamila said.
The representative of the Nigeria Governors’ Forum and Governor of Ogun State, Dapo Abiodun, who described State Police as a landmark reform, described the initiative as one of the defining reforms of President Tinubu’s administration.
Responding to concerns about federal overreach, he clarified that there is no Federal attempt to control State Police. He added that the proposed legislation is intended to provide an operational framework rather than centralise control.
Prince Lateef Fagbemi, the Attorney-General of the Federation and Minister of Justice, said the proposed National Policing Bill is designed to guarantee the security of lives and property while ensuring that the establishment of state police does not become a tool for political persecution.
The Attorney-General added that states not immediately ready to establish their own police services would continue to benefit from the presence of the Federal Police until they meet the required standards.
Other participants at the meeting included the Inspector General of Police, Tunji Disu; President of the Nigerian Bar Association, Afam Osigwe; Chairman, Policy Advisory Committee, Justice Abdullahi Liman (rtd); Professor Olu Ogunsakin, Head, Nigeria Police Reform Secretariat; Senior Special Assistant to the President on Planning and Research, Nnadubem Moghalu; and Brigadier General Olutayo Muyiwa Adesuyi, representing the National Security Adviser.

The Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA) says it recorded a 30 per cent reduction in gas imbalance on the country’s Western Network following the conclusion of its first-half 2026 Nigerian Gas Network Reconciliation (NGNR) Workshop.
The workshop brought together gas transporters, suppliers, shippers and off-takers to reconcile gas volumes traded between January and June 2026, while introducing a Network Entry/Exit Point Measurement Infrastructure Audit Template aimed at improving metering accuracy and accountability across the gas transmission network.
In a communiqué issued after the workshop, the authority said participants also reviewed the performance of the Nigerian Gas Transmission Network, assessed progress on major pipeline infrastructure projects, and received updates on the ELPS Gas Shrinkage Factor and Hydraulic Modelling Project.
Discussions focused on addressing metering gaps, improving network visibility through Supervisory Control and Data Acquisition (SCADA) integration, and enhancing system reliability ahead of the commissioning of the Ajaokuta-Kaduna-Kano (AKK) Pipeline System.
The workshop adopted key resolutions, including the execution of outstanding Network Exit Agreements, mandatory submission of measurement audit templates and closer collaboration among industry stakeholders to improve network pressure management.
Speaking at the closing session on behalf of the authority’s chief executive, Mr Rabiu A. Umar, the Director of Transportation Systems and Networks, Mr Joseph G. Musa, said the biannual reconciliation exercise had become critical to promoting equitable gas transactions, transparency, investor confidence and efficient network operations.
Mr Musa noted that since the NGNR process was introduced in 2023, it had significantly improved gas measurement, strengthened regulatory compliance through consequence management, reduced operational imbalances and contributed to a more reliable domestic gas supply.
The workshop concluded with participants adopting the reconciled H1 2026 gas volumes, reaffirming the authority’s commitment to a transparent, efficient and reliable domestic gas market.
