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.

Bill Seeking Creation of Unified Emergency Number Passes Second Reading

Unified Emergency Number

By Adedapo Adesanya

Nigeria’s crisis-response bill seeking to establish a single, toll-free, three-digit emergency number for nationwide use passed for second reading in the Senate this week.

Sponsored by Mr Abdulaziz Musa Yar’adua, the proposed legislation aims to replace the country’s chaotic patchwork of emergency lines with a unified code—112—that citizens can dial for police, fire, medical, rescue and other life-threatening situations.

Lawmakers said the reform is urgently needed to address delays, miscommunication and avoidable deaths linked to Nigeria’s fragmented response system amid rising insecurity.

Leading debate, Mr Yar’adua said Nigeria has outgrown the “operational disorder” caused by multiple emergency numbers in Lagos, Abuja, Ogun and other states for ambulance services, police intervention, fire incidents, domestic violence, child abuse and other crises.

He said, “This bill seeks to provide for a nationwide toll-free emergency number that will aid the implementation of a national system of reporting emergencies.

“The presence of multiple emergency numbers in Nigeria has been identified as an impediment to getting accelerated emergency response.”

Mr Yar’adua noted that the reform would bring Nigeria in line with global best practices, citing the United States, United Kingdom and India, countries where a single emergency line has improved coordination, enhanced location tracking and strengthened first responders’ efficiency.

With an estimated 90 per cent of Nigerians owning mobile phones, he said the unified number would significantly widen public access to emergency services.

Under the bill, all calls and text messages would be routed to the nearest public safety answering point or control room.

He urged the Senate to fast-track the bill’s passage, stressing the need for close collaboration with the Nigerian Communications Commission (NCC), relevant agencies and telecom operators to ensure nationwide coverage.

Senator Ali Ndume described the reform as “timely and very, very important,” warning that the absence of a reliable reporting channel has worsened Nigeria’s security vulnerabilities.

“One of the challenges we are having during this heightened insecurity is lack of proper or effective communication with the affected agencies,” Ndume said.

“If we do this, we are enhancing and contributing to solving the security challenges and other related criminalities we are facing,” he added.

Also speaking in support, Senator Mohammed Tahir Monguno said a centralised emergency number would remove barriers to citizen reporting and strengthen public involvement in security management.

He said, “Our security community is always calling on the general public to report what they see.

“There is a need for government to create an avenue where the public can report what they see without any hindrance. The bill would give strength and muscular expression to national calls for vigilance.”

The bill was referred to the Senate Committee on Communications for further legislative work and is expected to be returned for final consideration within four weeks.

Cut Energy Costs

By Adedapo Adesanya

The Special Adviser to President Bola Tinubu on Energy, Mrs Olu Verheijen, says Presidential Directives 41 and 42 have emerged as the most transformative policy tools reshaping Nigeria’s oil and gas investment landscape in more than a decade, by helping eliminate bottlenecks.

Mrs Verheijen made this assertion while speaking at the Practical Nigerian Content Forum 2025, noting that the directives issued by her principal in May 2025, are specifically designed to eliminate rent-seeking, slash project timelines, reduce contracting costs, and restore investor confidence in the Nigerian upstream sector.

“These directives are not just policy documents; they are enforceable commitments to make Nigeria competitive again,” she declared.

She noted that before the directives were issued, Nigeria faced chronic delays in contracting cycles, which discouraged capital inflows and stalled major upstream projects.

“For years, investment stagnated because our processes were too slow and too expensive. Presidential Directives 41 and 42 are removing those bottlenecks once and for all,” she said.

According to her, the directives have already begun to shift investor sentiment, unlocking billions of dollars in new commitments from international oil companies.

“We are seeing unprecedented investment inflows. Shell, Chevron and others are returning with confidence because they can now see credible timelines and competitive project economics,” Verheijen said.

Speaking on the link between streamlined contracting and local content development, she stressed that the directives were crafted to reinforce, not weaken, Nigerian participation.

“Local content is not an obstacle; it is a catalyst. It helps us meet national objectives, contain costs, and deliver projects faster when applied correctly,” she explained.

Mrs Verheijen highlighted that the directives complement the government’s data-driven approach to refining local content requirements while ensuring Nigerian talent and enterprises remain central to new investments.

“Our goal is to empower Nigerian companies with opportunities that are commercially sound and globally competitive,” she said.

She pointed to the current spike in industry activity, over 60 active drilling rigs, as evidence that the directives are driving real operational change.

“We have moved from rhetoric to results. These directives have triggered a new cycle of upstream development,” she said.

The energy expert added that the reforms are critical to achieving Nigeria’s production ambition of 3 million barrels of oil and 10 billion standard cubic feet (bscf) of gas per day by 2030.

“To meet these targets, we need speed, efficiency, and collaboration across the value chain. The directives are the foundation for that,” she noted.

She also linked the directives to Nigeria’s broader regional ambitions, including its leadership role in the African Energy Bank.

“With a $100 million facility now launched, we are ensuring that investment translates into jobs, technology transfer, and long-term value for Nigeria,” she said.

Mrs Verheijen concluded by urging the industry to uphold the spirit and letter of the presidential instructions.

“These directives are a collective responsibility. Government, operators, financiers, and host communities must work together to deliver the Nigeria we envision,” she said. “We remain committed to ensuring Nigeria remains Africa’s premier investment destination,” she said.
