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.

National Albinism Day: AAN Reiterates Call for Inclusive Policy

Albinism association of nigeria albinism group

By Adedapo Adesanya

As Nigeria marks National Albinism Day, the Albinism Association of Nigeria (AAN) has reaffirmed its commitment to advocating for the rights, health, and inclusion of persons with albinism (PWAs), urging the government and relevant stakeholders to adopt inclusive policies that address their unique challenges.

Established in 2019, AAN has been at the forefront of championing the welfare of persons with albinism across the country. Through targeted advocacy, education, and partnerships, the association has significantly contributed to increased societal acceptance, reduced school drop-out rates among children with albinism, and greater attention to their health needs at national forums.

According to the organisation, this year’s theme, Protect Your Skin, Be Sun Smart underscores the pressing need to address the health vulnerabilities of PWAs, especially those resulting from sun exposure. Due to the absence of melanin—the natural pigment that protects the skin from harmful ultraviolet (UV) rays—persons with albinism are prone to painful sunburns, premature skin aging, vision problems, and an increased risk of skin cancer.

AAN emphasized preventive measures such as the regular use of broad-spectrum sunscreen (SPF 30 or higher), wearing protective clothing including wide-brimmed hats and sunglasses, avoiding peak sunlight hours, and seeking routine medical checkups for early detection of skin conditions.

In a statement shared with Business Post, Mrs Bisi Bamishe, National President of AAN, made a strong appeal to the government:

“We are calling on the Nigerian government to include sunscreen in the list of essential medicines under the National Health Insurance Scheme (NHIS). Sunscreen is not a luxury for persons with albinism—it is a necessity for survival.”

She further stressed the need for more tangible support

“Government should provide free or subsidized protective gear and health services to persons with albinism, especially in rural and underserved areas.”

Highlighting the importance of awareness and capacity building, Mrs. Bamishe said, “We urge health workers and teachers to receive proper training on the specific needs of persons with albinism. This will go a long way in improving service delivery and reducing stigma in schools and health centres.”

She also emphasized the importance of legal protections.

“The Discrimination Against Persons with Disabilities (Prohibition) Act must be enforced. It is not enough to have laws on paper; we need full implementation to ensure justice and inclusion.”

“We call for public education campaigns to reach deep into rural communities where harmful myths and stereotypes still persist. Awareness is key to acceptance.”

AAN also stressed the need for capacity building initiatives to empower community advocates and peer support systems.

As National Albinism Day is observed, AAN urges Nigerians to stand in solidarity with persons with albinism and work collectively to create a more inclusive, informed, and equitable society.

GenCos

By Adedapo Adesanya

President Bola Tinubu will meet with the leadership of electricity-generating companies (GenCos) over the N4 trillion power sector debt on Tuesday, May 6.

This was disclosed by the Special Adviser on Strategic Communications and Media Relations to the Minister of Power, Mr Adebayo Adelabu, who noted that the federal government vowed to urgently address the debt following high-stakes talks between the Minister and chairmen of the power generators in Abuja recently.

He said FG’s intervention was aimed at averting an imminent collapse of the power infrastructure in the country.

Recall that the Minister also promised that the FG will pay 50 per cent of the debt recently.

According to the statement, the Minister assured the GenCos executives that the government would prioritise immediate payment of a significant amount out of the N4 trillion debt, while the balance would be defrayed through other debt instruments.

He said this would be proposed in a meeting being planned between President Tinubu and GenCos’ leadership.

“There is need to pay a substantial amount of the debt in cash. At the minimum, let us pay a substantial amount, then ask for a debt instrument in promissory notes to pay the rest,” he stated, assuring that the payment of the outstanding balance within six months through financial instruments such as promissory notes.

“We recognise the urgency of this matter. The government is committed to resolving this debt to stabilise the sector and prevent further crisis,” Mr Adelabu stated, adding that the President will meet with GenCos leadership to fast-track the process.

The GenCoS were led by the Chairman of Mainstream Energy Solutions, who is also the Chairman of the Association of Power Generating Companies (APGA), Mr Sani Bello, who had earlier sounded the alarm over the sector’s dire state, citing the N4 trillion debt as a critical threat to operations.

He also warned that liquidity challenges had left GenCos unable to secure loans or maintain infrastructure. “Without urgent intervention, the entire power ecosystem could collapse,” he stressed.

Mr Kola Adesina, Chairman of Egbin Power and First Independent Power Limited, echoed the urgency: “This is a national emergency. Everything hinges on power—industries, homes, hospitals. We cannot afford to let the sector fail.”

Mr Adelabu acknowledged the government’s role in the sector’s struggles, pledging to not only clear the debt but also implement reforms to ease operational bottlenecks. He emphasised the need for full liberalisation of the power sector, urging Nigerians to embrace cost-reflective tariffs.

“Citizens must pay the appropriate price for the energy consumed. The Federal Government will continue to provide targeted subsidies for economically disadvantaged Nigerians. We have to understand that our economy cannot sustain subsidies indefinitely,” he asserted, calling for public sensitisation campaigns to drive compliance.

On her part, Mrs Joy Ogaji, CEO of APGC Power, detailed systemic challenges undermining GenCos, including chronic payment defaults, erratic gas supply, and foreign exchange volatility.

She noted that the naira’s plunge from N157/$1 in 2013 to N1,600/$1 had devastated maintenance budgets and loan repayments.

“GenCos have borne unsustainable risks—from grid failures to unproductive taxes—while remaining patriotic,” she said.

electricity tariffs

By Modupe Gbadeyanka

The Minister of Power, Mr Adebayo Adelabu, has advised Nigerians and electricity consumers in the country to brace up for another hike in tariff because the federal government is not buoyant enough to continue to bear the cost of subsidy on electricity.

Speaking at a meeting with the Chairmen of the Generating Companies of Nigeria (GenCos) in Abuja, Mr Adelabu said consumers will soon begin to pay cost-reflective tariffs.

At the moment, customers on Band B to E enjoyed subsidised electricity tariffs and pay between N68 per kilowatt per hour and 34 per kilowatt per hour (VAT inclusive), while those on Band A, who consume power for at least 20 hours per day, pay about N225 per kilowatt per hour (VAT inclusive).

At the meeting with the GenCos, the Minister hinted that consumers on Band B downward may have to pay more, which could match the Band A tariff.

“We have to understand that our economy cannot sustain subsidies indefinitely,” Mr Adelabu informed the chairmen without giving a specific time when a new rate will be announced.

During the meeting, the chairman of Egbin Power, Mr Kola Adesina, tasked the government to declare a state of emergency in the power sector, noting that the N4 trillion owed GenCos by the federal government remains a critical threat to their operations.

“This is a national emergency. Everything hinges on power—industries, homes, hospitals. We cannot afford to let the sector fail,” he stressed.

Also, the chairman of Mainstream Energy Solutions, Mr Sani Bello, warned that “without urgent intervention, the entire power ecosystem could collapse.”

In the same vein, the chief executive of the Association of Power Generating Companies (GenCos), Ms Joy Ogaji, said, “GenCos have borne unsustainable risks—from grid failures to unproductive taxes—while remaining patriotic.”
