FG Gets Siemens’ Plan to Raise Power Supply to 25,000MW

The federal government has received a comprehensive plan, ‘the Nigeria Electrification Roadmap: Technical and Commercial Proposal,’ from German power firm, Siemens, on how the firm would help raise the country’s power supply capacity to 25,000 megawatts (MW).

THISDAY gathered that the implementation of the plan might be led by the Bureau of Public Enterprises (BPE) on behalf of the government, with the Ministry of Power, Nigerian Electricity Regulatory Commission (NERC) and Nigerian Bulk Electricity Trading Plc (NBET), playing roles as well.

The proposal was sequel to the signing of a letter of Agreement on Nigerian Electrification Roadmap, conceived to deliver 7,000 megawatts of electricity in 2021 and 11,000 megawatts in 2023, between President Muhammadu Buhari and the global Chief Executive Officer of a German company, Siemens AG, Joe Kaeser, in July. The third phase of the agreement will dovetail in the delivery of 25,000 megawatts of electricity.

The proposal, which was sighted by THISDAY yesterday, contained what Siemens considered would be done to help Nigeria improve power supply from the grid in three phases of 7,000MW, 11,000MW, and 25,000MW over a period of six years.

It identified 103 upgrade and new projects to be implemented in 10 of the 11 distribution networks of the country, as well as plans to raise the country’s transmission infrastructure with complementary supervisory control and data acquisition (SCADA) system.

Siemens also offered to support the Nigerian National Petroleum Corporation (NNPC) build the three new power plants it had proposed in Abuja, Kaduna and Kano, to collectively produce 4,050MW of electricity when completed.

THISDAY gathered they would be part of the 25,000MW overall generation target in the Siemens proposal.

According to the document exclusively obtained by THISDAY, the plan in its phase one, will increase power delivered by additional 2,000MW, significantly reduce Aggregate Technical Commercial and Collection (ATC&C) losses of the Discos and achieve improved grid stability and reliability.

To achieve this, it will push to enhance the quality of the distribution networks and this will consist of swift supply of equipment needed for replacement and the immediate expansion, including upgrade of some substations.

“The first phase of the project will cover the supply of equipment required by the Discos for immediate use – Auto-Reclosure, Distribution Transformer, 11kV Air Insulated Switchgear, Ring Main Unit and, Compact Sub Station).

“This phase will be complemented with upgradation of existing substations in some Discos. The upgradation will cover expansion/replacement of existing medium voltage equipment, replacement of distribution transformer with a more powerful one as well as enhancement of the substation with an automation system and a communication facility.

“During the up-gradation period, a mobile substation is considered with the aim to avoid power supply interruption to consumers. Civil work for building adaptation, distribution transformer platform or outdoor platform will be considered for some substations,” the proposal said.

Siemens noted that a previous study it conducted for the 33 kilovolt (kV) sub-transmission networks of some Discos showed that the 7,000MW power supply scenario for Nigeria in the first phase could be implemented successfully with only minor upgrades and extensions in the 33kV networks of the Discos.

“Also, the 33 kV sub-transmission networks of the distribution utilities are able to accommodate this 7GW scenario with minor adaptations only.

Finally, the 11kV and LV distribution levels have shown to have suitable capacity in their existing status already, so that again only minor adaptations in individual cases will be required to implement the 7GW scenario from generation via transmission and distribution to the actual end-customers,” it added.

The aim of the first phase, Siemens said, would be to initiate these projects as quickly as possible so there would be visible impact in the grid within the next two years.

In the second phase of the plan, Siemens said it would focus on a bulk expansion of new 33/11kV injection substation and continue to upgrade other existing substations.
