The privatization strategy appears to be working in Nigeria after the government successfully sold 5 power generation and 11 distribution companies in 2014. The ongoing reforms in Africa’s largest economy also usher in Greenfield projects. GE is working closely with the new owners of privatized assets to ramp up power production. Independent Power projects in Nigeria that GE is currently working with include Ogorode, Benin, Omotosho, Olorunsogo and Alaoji Power Plants – all with a combined GE-enabled installed capacity of over 4000MW. These milestones are in fulfilment of the MOU GE signed with the Federal Government, committing to help generate additional 10,000 megawatts of electricity for Nigeria over ten years. In addition, GE is prepared to support the government with a holistic end to end initiative to tackle the c...

  • Applications of GIS in Oil and Gas Industry in Nigeria and Africa

    Pipeline monitoring. Pipelines need to be continually monitored to check for leaks, and geo-hazards, and to manage and track inspections, the frequency of which is often a regulatory requirement. Emergency response. GIS is becoming increasingly important in response to emergencies such as oil spills and gas explosions, both in mitigation planning and response management. Asset Management. A geodatabase stores, collects and manages the physical locations of features. In oil and gas, this includes pipelines, wells, pump stations and tank terminals. GIS can be used to Control Pipeline Vandalism of Oil and Gas Industry in Nigeria. The oil and gas industry is an extremely important segment of the world economy.

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, Sulfr hexafluoride, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in insulating gas gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what sf 6 can do in centimeters.
