Access to Energy Initiatives

Access to Energy

One of the world’s most critical development challenges is addressing the lack of access to reliable and affordable energy services for billions of people. Improving access to affordable and sustainable energy services is prominent on the international agenda and absolutely central to the broader development efforts to reduce poverty, improve education, health, gender equality and environmental sustainability.
NAOC contributes to the solution of the problem of access to energy in Nigeria through the following activities:

  • Supply of electricity through the Okpai Independent Power Plant (Delta State) to the Power Holding Company of Nigeria (completed and inaugurated by NAOC in 2005, installed capacity 480 MW, serving around 10 million customers);
  • Supply of gas to the Omoku IPP (Rivers State) (installed capacity 150 MW, serving around 1 million customers);
  • Supply of electricity to  communities directly  connected to NAOC  operational sites (capacity 38 MW, 36 beneficiary communities, about 300,000 people served);
  • Supply of electricity to the communities through off-grid system (capacity 15 MW, 44 beneficiary communities, about 160,000 people served).

Okpai Independent Power Project

Independent Power ProjectIn 2005, NAOC and its partners inaugurated a combined cycle power plant in Delta State with a 480 MW capacity. In 2017, via the Okpai power plant, NAOC contributed to access to energy in the Country by supplying energy to the Power Holding Company of Nigeria (PHCN) for nearly 2.400 million MWh, using 500 MMSCM of gas (associated and non-associated).
The Okpai Power Plant uses combined cycle technology, minimizing nitrogen oxide emissions per kWh produced. The sustainability of electricity and steam production is guaranteed by the natural gas-combined cycle cogeneration, which represents the best available technology for thermal-electric production. In fact, the technology and the fuel used allows the highest efficiency to be attained for electric power generation from fossil resources (up to 12 % greater than that of the latest coal plants), reducing the emission of pollutants for every kWh produced.

Project descriptioIndependent Power Projectn
The Okpai Plant, located near Kwale (Delta State) covers an area of 300,000m2 subject to seasonal flooding from the nearby Niger River and required a sand filling of 1,600,000m3. The Project was executed on a fast track schedule and the first unit entered in commercial operation just 20 months after the Final Investment Decision was taken. The Project mainly consists of important infrastructures in the location surrounding area. A 480 MW Integrated Combined Cycle Po wer Plant composed of 2 Gas Turbine Generation Sets of 165 MW each and a Condensate-Type Steam Turbine of 150MW; 14-Km, 18‘ Fuel Gas pipeline from NAOC Kwale Gas Plant to the Okpai IPP site; Substations and Over Head Transmission facilities. The Combined Cycle is a combination of two technological cycles: by air and natural gas (Open Cycle), efficiency = 34.28% and by water / steam (Water Steam cycle), fueled by the exhaust gas of Open cycle, boosting the efficiency to 55.03%. The Combined Cycle design is finalized at the production of electric power with high efficiency and minimum environmental impact.
Along with the Power Generation Complex, NAOC JV built 55 km of 330KV Overhead Transmission Line and 2 Substations (Okpai IPP & Onitsha Sub Station).
The double circuit system Over Head Transmission Line includes 130 towers, ranging from 80 m to 110 m in height and is capable of carrying the load for IPP Phase 1 and future expansion (IPP Phase 2).

The Okpai Phase 2 project has been initiated successfully and the project EPC is ongoing. A comprehensive Environmental Impact Assessment has been conducted and approved for the project and a Plant License has been issued by the National Electricity Regulatory Authority. Okpai Phase 2 is expected to double the capacity of the power plant, bringing the total capacity to almost 1GW. The project is foreseen to be completed in 2019 at which point the complex is expected to serve over 20 million consumers.

Communities directly linked to NAOC operational sites

NAOC supplies electricity to communities through the construction of networks connected to its operational sites. This activity involves construction of energy infrastructure to supply the communities of Bayelsa, Delta, Imo and Rivers States, maximizing the benefits generated from the presence of the industrial activities. The electricity is supplied to the communities by connection to NAOC operational sites present in the swamp area - including the Ogboinbiri and Obama flow stations, the Brass terminal, Tebidaba (project underway), as well as the Obiafu-Obrikom (Ob-Ob) gas plant, the Ebocha oil plant, the Kwale gas plant in the land area. Thanks to these operations, today the energy absorbed by the 36 communities connected to NAOC industrial plants is 38 MW (for an estimated total of 300,000 people).

NAOC also supplies energy to the local communities by constructing special off-grid systems to integrate the connections to the network built. NAOC supplies generators to 44 communities in the area, corresponding to an estimated population of 160,000, with a total power capacity of 15 MW. For the future, the company is embarking on a gradual plan to reduce community dependency on generators and integrate as many communities as feasible to the national grid by supporting local institutions with the necessary infrastructure to achieve this. A notable example is the Ahoada-West electrification project which serves as a pilot to connect several communities in the Local Government Area to the PHCN grid.
