Electricity is one of the most important invention of Man. It powers the economy and everything in a Nation. This work seeks to carryout a critical review of Nigeria’s energy crisis. A PricewaterhouseCoopers, PwC reports asserts that Nigeria still ranks 2nd worst in the global electricity access charts; a significant portion of electricity is generated from private generators at a higher cost of NGN 120/kWh while grid-based cost NGN 4-5/kWh; more than 50% Nigerians do not have access to electricity, however amongst the other 50% who have access, experience intermittent power supply; 5 - 6 times increase in electricity consumption required to match peer countries with similar GDP per capital; 25 % of potential energy reaches the end-user: Structural inefficiencies across the power value chain prevent electricity from reaching end-users. This work sets out to chronicle Nigeria’s energy crisis: its challenges and prospects. Results from various reviews show that the major issue plaguing the nation’s electricity sector isn’t so much about resources, which the Nation has in abundance, albeit, some in potential state. From the reviews so far, the following are the major problems: 1. The National question 2. Lack of technical know-how 3. Sabotage of government’s efforts and destruction of power sector physical assets. 4. Inconsistency in Policy formulation and implementation. The work therefore, proposes that for the long run, the nation tries to solve her national question; however, for the short run, the Federal Government should adopt the NLNG business model that has produced fantastic results for all its shareholders and stakeholders. The researchers therefore strongly advice the Federal Government to adopt the business model of the Nigeria Liquified Natural Gas, NLNG Company.

Bus System

Conventionally in many countries, electrical power industry is organized as vertically integrated system. Under this system, large utilities are authoritative for the generation, transmission and distribution of electrical power. Such utilities are governed by the rules and regulations of the government and are forced to operate within the prescribed guidelines with minimal profit. This confirmation causes an ineffective and sluggish perspective in power industry with a lack of technical innovation, competent management and customer satisfaction. To overcome these deficiencies, power sector around the globe is getting restructured. This paper addresses an inevitable technical disputes occurring in deregulated environment i.e., transmission congestion which has an adverse effect on system security, increase in electricity pricing and line losses. Flexible AC Transmission System (FACTS) is a boon to the power sector which helps in a better and reliable power flow through the transmission lines. The problem is articulated as a multi objective function satisfying all the operational and security limits. Three heuristic algorithms namely Particle Swarm Optimization (PSO), Symbiotic Organism Search (SOS) and hybrid Quantum based PSO-Bio-geography based krill herd optimization (Q-PSOBBKH) algorithms were applied in finding solution to this complex congestion problem. To study the effectiveness of the proposed objective, IEEE 14 bus system was considered as the test system. In order to validate the proposed methodology three congestion cases i.e. bilateral transaction, multilateral transaction and overloading were imposed on the test bus system. Simulation was carried out in MATLAB.

Project Objectives

Schedule reliability is essential to successfully achieve EPC (engineering, procurement and constriction) project objectives. Several studies in the past were based on traditional risk management technique which has its own limitations that lack one to obtain a reliable project schedule. To overcome these limitations a comprehensive framework is developed based on the integration of risk management and Critical Chain Project Management (CCPM) that can give a much reliable project scheduling. In the proposed framework, risk analysis is first determined through fuzzy FMEA technique to provide identification of critical risk events (CRE). The effect of CRE on project schedule is then defined and total project time which considers risk factors is calculated. To support risk mitigation, fault tree and event tree analysis are combined which allows the root causes of the risk event be defined and also mitigation strategies determined to control each identified CRE. Eventually, CCPM is distributed which enable implementation of the project based on initial plan and to obtain reasonable Feeding Buffer time on risky tasks. This paper presents the proposed framework using a real case study on construction phases of EPC projects in an electrical power industry.

The Way

China's electrical power industry has been undergoing piecemeal reforms over the last 15 years. Some of these reforms, such as substantial tariff increases, have been deliberate and have been implemented directly by government. Other changes, such as the increased variety of investors, including foreign investors, have been more spontaneous and have resulted in a gradual evolution in the way the industry works. In 1996 the Chinese government announced a more radical package of reform starting with the new Electricity Law which laid the foundations for a degree of competition in power generation, but without wholesale privatization.
