SCADA system

By Adedapo Adesanya

To tackle the reoccurring cases of grid failure, the federal government has said it would fast-track the purchase and installation of a Supervisory Control and Data Acquisition (SCADA) system.

The SCADA system is software used to monitor and control an electrical grid system based on the information it collects from the substations within that system.

This is as the country witnessed the fifth grid collapse this year over the weekend.

Following the federal government’s failure to acquire the SCADA, the supply system has been unable to provide remote coverage and relay of interconnected network communication to enable Distribution Companies (Discos) have real-time access to monitor and control their distribution infrastructure.

This indicates that Nigeria’s discos still use the analogue system of detecting faults within their networks.

However, the FG said SCADA would assist in monitoring/controlling existing injection and distribution substations.

It would further reduce downtime, help in faults location, track and restore the system in cases of collapses, increase revenue generation as well as reduce Aggregate Technical, Commercial and Collection (ATC&C) losses.

In March 2022, the country witnessed a blackout twice amid a severe fuel crisis as well as in January and February this year. The latest system collapse occurred twice within a few hours.

The grid, which is being managed by the government-owned Transmission Company of Nigeria (TCN) has continued to suffer system collapse over the years amid a lack of spinning reserve that is meant to forestall such occurrences.

A statement issued on Saturday by the Minister of Power, Mr Abubakar Aliyu, signed on his behalf by his Special Adviser, Media, Mr Isa Sanusi, noted that the stakeholders were working round the clock to ensure that normalcy is restored as soon as possible.

Mr Aliyu added that power has already been restored in several parts of the country since the latest incident, noting that it was carrying out reforms to ensure that such power failures are reduced to the minimum.

“We wish to notify the general public of the incidence of a system collapse which occurred at 1830 hours on April 8, 2022, resulting in power outages in many parts of the country.

“While a detailed investigation into the immediate and remote causes of the recurring grid failure is currently ongoing by the Nigerian Electricity Regulatory Commission (NERC) and System Operator (the operator of the national grid), the process of restoring supply is ongoing with some sections of the national grid already energised and supply restored to consumers.

“We wish to assure Nigerians that the federal government is working assiduously to deliver on the much-needed reforms and investments, including SCADA, that are critical to improving the capacity and reliability of the national grid.

“This is in line with the Mr President’s directives on closing infrastructure deficits in critical sectors of the Nigerian economy,” the minister explained.

Also, the FG blamed the current nationwide blackout on the damage done by suspected vandals to one of its facilities in the Niger Delta.

It stated that the vandalism of the transmission tower in Odukpani Ikot- Ekpene resulted in the substantial loss of power generation.

“Further to our earlier press release, we wish to apprise the general public that the immediate cause of the national blackout (system collapse) was an act of vandalism on a transmission tower on the Odukpani Ikot Ekpene 330kV double circuit transmission line.

“This resulted in a sudden loss of about 400MW of generation. This consequently led to a cascade of plant shutdowns across the country.

“We wish to notify the public that power on the grid is being restored sequentially by the system operator as other on-grid power plants are being dispatched to cover the lost generation capacity from the Calabar power plant owned by the Niger Power Holding Company Ltd.,” the Minister noted.

GE Reduces Emissions With Mobile Gas Turbines

Published

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.

State House 2023 capital budget

By Adedapo Adesanya

The Senate has threatened to withhold the 2023 capital budget of 100 federal Ministries, Departments and Agencies (MDAs) until they answer the queries raised against them by the Auditor General for the Federation.

Senate President, Mr Ahmad Lawan, issued this threat on the floor of the upper chamber of the National Assembly on Wednesday while ruling on a point of order.

The threat followed a point of order raised by the Chairman of the Senate Committee on Public Accounts, Mr Matthew Urhoghide, who informed his colleagues that some agencies refused to appear before the team despite invitations sent to them.

Some of the MDAs include the State House, Office of the Accountant General of the Federation, Ministries of Interior, Transportation, Mines and Solid Mineral Development, Information, Communication, Petroleum, Defence, Police Affairs, and Sports.

Others are Works and Housing, Women Affairs, the State House, Presidential Fleet, Nigeria Security and Civil Defence Corps, Independent National Electoral Commission, North East Development Commission, Nigerian Intelligence Agency, and the Nigerian Air Force, among others.

The queries covered in the auditor general’s report are from 2015-2018.

Speaking, Mr Lawan upheld Mr Urhoghide’s point of order and insisted that the public officers who utilised funds appropriated to their MDAs must give account.

He said, “Your point of order is sustained fully and completely, totally sustained; you are right on the dot to bring to the plenary your grievances.

“Secondly, I once served as Chairman of the Public Accounts Committee for eight years. My only problem is when you write agencies, and they refuse to honour the invite, you’d many times be forced to bring them through a warrant of arrest.

“Reading this list at plenary gives the agencies the opportunity to know now if they were not aware before for those that may claim ignorance.”

The Senate then gave the agencies a one-week deadline to communicate with the committee and set a date to appear before them or have their capital budgets withheld.

“I am taking the opportunity here to advise that in the next one week, if the name of any agency is here, that agency should reach the Committee on Public Accounts of the Senate to sort out when the agency would appear before the committee.

“If there is no communication whatsoever and no cogent and verifiable reason are given, we will slash the agencies’ budget.”
