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.

Violent Protest Erupts in Ibadan Over Naira Scarcity

protest in Ibadan

By Aduragbemi Omiyale

There are reports of a violent protest in Ibadan, the Oyo State capital, over the scarcity of old and new Naira notes, Business Post has gathered.

It was learned that residents of the ancient city are venting their anger over the hardship caused by the policy of the Central Bank of Nigeria (CBN) and the federal government.

The central bank redesigned the N200, N500, and N1,000 notes and asked citizens to return their old banknotes because they would cease to be legal tender.

However, since the introduction of the new currency notes in circulation on December 15, 2022, many Nigerians have not been able to withdraw their money from banks, fuelling anger in the land.

On Friday afternoon, some residents of Ibadan, especially in Iwo Road, took to the streets to express their frustration at the development, which is coming at a time consumers have to queue for petrol.

They had bonfires on the road and disrupted business activities in some areas of the city.

Recall that today, the Governor of Oyo State, Mr Seyi Makinde, announced the suspension of his campaign activities over the scarcity of Naira and fuel.

Also on Friday, the Governors of the ruling All Progressives Congress (APC) met with President Muhammadu Buhari to appeal to him to change his mind on the Naira swap policy because of the effect on the people and the 2023 general elections starting later this month.

The President had earlier been asked not to show up in Kano State because of fears of a violent protest over the development. After the deadline was moved forward, the Governor of the state, Mr Abdullahi Ganduje, said he was safe to visit the ancient city.

However, during his visit to Kano, there were reports of a demonstration, with a chopped stoned by some residents of the state and convoys attacked by angry protesters.

The government claimed the protest was not directed at President Buhari, while the opposition party, Peoples Democratic Party (PDP), said otherwise.

APC Governors

By Aduragbemi Omiyale

President Muhammadu Buhari has been urged to allow the use of old and Naira notes as legal tender in the country until the former is naturally mopped up from the circulation.

This appeal was made on Friday by Governors elected on the platform of the ruling All Progressives Congress (APC) during a meeting with Mr Buhari at the Presidential Villa, Abuja.

In a brief chat with reporters after the meeting, the Governor of Kano State, Mr Abdullahi Ganduje, said after the request was made to the President, he promised to look into it.

The Central Bank of Nigeria (CBN) last month redesigned the N200, N500, and N1,000 banknotes and said the old currency denominations would cease to be legal tender from January 31, 2023.

However, two days before the deadline, the Governor of the CBN, Mr Godwin Emefiele, after a meeting with President Buhari in his hometown in Daura, Katsina State, said the deadline had been shifted to February 10, 2023, noting that Nigerians had a grace period of February 17, 2023, to return the old notes to the bank.

On Tuesday, January 31, he appeared before the House of Representatives ad-hoc committee on the CBN policy to say Nigerians could still take their old notes to banks after the deadline, promising that citizens will not lose their funds.

Today, the APC Governors met with Mr Buhari to discuss the scarcity of Naira in the financial system and also the lingering fuel scarcity.

One of the Governors present at the gathering, Mr Nasir El-Rufai of Kaduna State, had claimed this week that the scarcity of cash and petrol was the handiwork of some elements in the Villa, who do not want the party to succeed in the forthcoming elections.

“We spoke with the President to allow the old and new notes to co-exist until the old notes die a natural death,” Mr Ganduje told newsmen while walking out after the meeting.

“Sir, did you discuss the petrol scarcity with him,” one of the reporters asked the Kano Governor, and he responded, “Yes.”

Makinde campaign activities

By Aduragbemi Omiyale

Due to the unending fuel and new Naira notes crisis rocking the country, Governor Seyi Makinde of Oyo State has suspended his campaign activities.

Mr Makinde is seeking another term in office under the platform of the Peoples Democratic Party (PDP).

He commenced his campaign activities last month, asking residents of the state to give him another chance to serve them.

But the scarcity of premium petrol spirit (PMS), otherwise known as petrol, and cash has put Nigerians under untold hardship.

Governor Makinde, during the flag-off of the Omi-Adio-Ido Road on Friday, said in solidarity with the people over anti-people economy policies of the All Progressives Congress (APC) led federal government, he would be suspending his campaign.

A statement by the Commissioner for Information, Culture and Tourism, Mr Wasiu Olatubosun confirmed this.

In the statement, Mr Makinde, who was in Ido to continue his campaign, directed that all campaign activities be suspended until further notice.

Mr Olatubosun said Governor Makinde noted that the suffering of his people was too much, saying he was elected to protect their interests and well-being.

The Commissioner said his boss, in an emotionally laden voice, directed leaders of the party in Oyo State to suspend the campaign.

“As a mark of honour to citizens and residents of Oyo State, the Governor of Oyo State, Seyi Makinde, has directed that all campaign activities of the party at all levels be suspended until further notice,” the statement read.

“Governor Seyi Makinde’s love for his people necessitated this unprecedented move at this time. We urge all residents and citizens of the State to remain calm as we navigate through this difficult period together,” he added.
