The Nigerian Independent System Operator (NISO) says electricity generation on the national grid has declined due to gas supply constraints caused by a reported gas pipeline vandalisation in the upstream supply network.
In a statement on Tuesday, the operator said the incident disrupted gas supply to several power generation facilities.
“The Nigerian Independent System Operator (NISO) wishes to inform the general public and sector stakeholders that electricity generation on the National Grid has dropped due to gas supply constraints arising from the reported incident of gas pipeline vandalization within the upstream gas supply network,” the statement reads.
“The incident affected gas availability to a number of power generation facilities.
“Consequently, several gas-fired power stations recorded low output, which resulted in reduced available generation capacity on the National Grid.”
In response to the development, NISO said it immediately implemented established contingency measures to ensure system stability and reliability.
“These measures included increased dispatch from available hydroelectric power stations, continuous generation re-dispatch, voltage control interventions, and other necessary operational actions to balance electricity supply with system demand,” the operator said.
“We are closely monitoring grid conditions, including system frequency and voltage profiles, while working with relevant stakeholders to mitigate the impact of the gas supply constraints.
“The situation highlights the importance of coordinated efforts to address gas supply disruptions, particularly as we approach the festive season, which is traditionally sensitive for grid operations.”
NISO assured the public of its commitment to proactive grid management and adherence to operational standards to provide a secure, stable, and reliable electricity supply across the country.
On December 12, the Nigerian National Petroleum Company (NNPC) Limited reported an explosion on its Escravos-Lagos gas pipeline, operated by the NNPC Gas Infrastructure Company (NGIC) pipeline.
