Shiroro and six others power plants have suffered from the low load demand by the electricity distribution companies.
The seven power plants in the country could not generate a total of 720 megawatts on Sunday as a result of DISCOS electricity load rejection.
As at a result of gas constraints, low load demand by Discos and water management a total of 1952.5 megawatts of generation capacity was idle 6am on Sunday.
Data obtained by Punch from the Nigerian Electricity System Operator as of 6am on Sunday, showed that the power plants on the national grid generated 4424.2MW
The affect power plants include two of the country’s four hydropower plants, namely Shiroro and Jebba. Others were Odukpani (NIPP), Geregu I, Afam IV&V, Geregu II (NIPP), and Rivers IPP.
According to the system operator, eight power plants did not generate electricity as of 6am on Sunday
The idle plants were Alaoji, Ihovbor, Gbarain, Ibom Power, ASCO, AES, Trans-Amadi and Egbin ST6.
Nigeria generates most of its electricity from gas-fired power plants, while output from hydropower plants makes up about 30 per cent of the total generation.
The Nigerian Electricity Regulatory Commission, in its recent Guidelines for Implementation of Economic Merit Order Dispatch and Other Related Matters, said Discos that reject electricity load due to constraints in their networks would have to pay for the capacity charge of the rejected energy.
It said this was in accordance with the December 2019 Minor Review of the Multi-Year Tariff Order 2015 and Minimum Remittance Order for the Year 2020.
The commission said Section 11 of the order directed that the “Nigerian Bulk Electricity Trading company shall hereafter invoice for capacity charge and energy to Discos based on their load allocation and metered energy respectively.”
It said Section 12 of the order concluded that “where it is established that the Transmission Company of Nigeria is unable to deliver a Disco’s load allocation, TCN shall be liable to pay for the associated capacity charge.
“Where a Disco fails to take its entire load allocation due to constraints in its network, the Disco shall be liable to pay the capacity charge as allocated in its vesting contract.”
