Nigeria Minigrids Rural Electrification Program REP
Potential Electrification in Rural Area
Energy is crucial to the wellness of humans and to a country’s economic development.
Nigeria is challenged with low availability of electricity in rural areas as shown in the Map. And unreliability in the urban centers.
Renewable Energy from Solar, Biomass and coal residue (Gasification) , and Hydro are the best alternative approach to solving the country’s electricity problem.

GRP Project Analysis: Brief History, Actual Status and Future Development
GRP will be located in the local government area of Warri South West, Delta State in Southern Nigeria.
Warri South West is directly adjacent to Warri City, the capital of Delta State.
Phase 1 of the Refinery will be installed on a parcel of land (with direct access to the coastlines of Escravos river) area measuring 60 hectares from a total available Land of 500 Hectares for Future Expansions.
GRP will benefit from a Jetty on Chanomi Creek- Escravos River Waterways downstream to Guinea Gulf in the Atlantic Ocean.
The Project is located in a peaceful and welcoming community as Chevron and Seplat being operative safely for the last 50 years.
GRP Project Conceptual Engineering Design – Modular Refinery technology
CRUDE DISTILLATION UNIT: Crude distillation is one of the first and most critical steps of the petroleum refining process. It separates crude oil, a complex mixture of many different hydrocarbon compounds, into fractions based on the boiling points of the hydrocarbons.
NAPHTHA HYDROTREATING UNIT: The Naphtha Hydrotreating unit is necessary to remove Sulphur and other contaminants prior to using the naphtha as feed to catalytic reformer. The process uses hydrogen at specific temperatures and pressures in the presence of a catalyst to remove sulphur, nitrogen, and metals and to saturate olefins and potentially aromatics compounds.
CATALYTIC NAPHTHA REFORMING UNIT: In the catalytic naphtha reforming process, naphtha is reacted with a platinum-based catalyst at elevated temperatures and with hydrogen at a specified pressure. The naphtha produces a high-octane liquid product (reformate) and by-products of hydrogen and process gas. The reformer produces enough hydrogen to supply the NHU. The high-octane reformate is rich in aromatic compounds.
GRP Project Conceptual Engineering Design – Regulatory Framework from DPR
APPROVAL PROCESS FOR THE DESIGN, CONSTRUCTION, COMMISSIONING AND
OPERATION OF A PROCESS PLANT
The approval process described hereunder is designed to ensure that the applicant for approval and permit to establish a Petroleum Refinery (or a process plant), understands the industry, the technical and economic implications of the project, the sociological and environmental impact of the plant, and maintenance provisions required to protect the health of the operating staff and safety of plant. It is designed to prevent avoidable waste of resources by ensuring at each stage that the applicant understands the statutory requirements of each phase of the project. Consequently, the approval shall be given in three sequential stages: License to Establish (LTE), Approval to Construct (ATC) and License to Operate (LTO) respectively
GRP Project Impact and Logistics: Environmental, Social, Corporate Responsibility
Environmental and Social Impact Assessment (ESIA) completed and Granted by the Federal Ministry of environment for the refinery and all utilities and supporting infrastructures (including Power Plant).
Conducted over 15 kilometres radius of the site by seasoned professionals.
All impacted communities and beyond were engaged.
Kingdom Chiefs meeting to discuss project with all the communities, State Government, Nigerian Local Contents Monitoring and Development Board, DPR, Federal Ministry of Environment, etc.
Detailed community development plan will be developed with our partners as required by the Nigerian Contents Development and Monitoring Board (NCDMB).
GRP will work as per the guidelines of the ESIA which concluded that the significant potential benefits of the project substantially outweigh the potential negative impacts.
GRP Project Impact and Logistics: site access
A.Generalities:
1.The Connectivity to the hinterland and to the Atlantic Ocean is through Escravos River and navigable waterways in Delta states leading to ports of Warri, Sapele, Koko,Forcados……..
2.Chanomi Creek and nearby navigational waterways are dredged and maintained from oil and Gas Companies.
3.Presently, coastal tankers transporting refined petroleum products from offshore to Delta State ports navigate the waterways because of their relatively lighter deadweight tonnages.
