Key Issues on Power Supply Insufficient generation capacity - Grid- based power generation capacity in sub- Saharan Africa has increased from around 68 GW in 2000 to 90 GW in 2012, with South Africa alone accounting for about half of the total (WEO, 2014) Poor reliability - .. many firms operate their own diesel generators at two to three times the cost with attendant environmental costs N ige r ia Other West Cen t ra l East Southe r n 8 Industry Serv i ces Residentia l 10 12 TWh 2 4 6 S ou rce: A fr i ca E nergy Outlook, 2 01 4 -

Key Issues on Power Supply (Continued} Power Generation : Power plants in sub- Saharan Africa consists largely of technologies with the lowest efficiencies , often favored due to their lower upfront capital costs. Average efficiency of the fleet of gas- fired power plants was 38% in 2012, due to the predominance of open- cycle gas turbines (instead of higher efficiency combined- cycle gas turbines) Average efficiency of gas- fired power plants in India (46%) Unused fuel could have generated 8 TWh (21 %) more electricity (WEO 2014). - Source : http://www.m a c auh ub . eom . m o/en/20 1 2/07/2 5 / m ozamb i q u e - will ­ h ave- three - mor e - nat ur a l - gas- f ir ed- power- plants/

Energy Efficiency Possibilities on the Supply Side - T&D Use of energy efficient distribution transformers: They are among the most ubiquitous and the most standardized pieces of electrical equipment, and for that reason make a prime target for improvements that can then be propagated across large areas . Use of High- Voltage Direct Current (HVDC) for long distance transmission -

Value of energy efficiency and conservation Department of Energy, MoEM, Somaliland Successfully capturing Somaliland’s energy efficiency potential will be critical for the electricity sector – relieving constraints in the current network, lowering total system costs, and improving value and service for customers – with significant benefit to both human and economic development as a result .. Demand-side management (DSM) can reduce the cost of grid investments, providing a lower cost alternative to T&D upgrades, or improving service at overloaded feeders while waiting for grid expansion. Energy efficiency (EE) can reduce total system cost of generation, transmission, and distribution in the long-term. Support for EE investment and implementation can help offset the impact of rising electricity prices on consumers and industries

The EE&C directorate activities include: Development , review and update of the Action Plan; Development of detailed proposals for individual projects; Funding applications for projects and programs; Data gathering and management; and Reporting and monitoring.

What is blocking application of and investments in Energy Efficiency in Africa? Energy- efficiency potentials are not being realised, even when they are economically cost- effective. Numerous barriers impede their adoption and rapid market diffusion Lack of information on energy efficiency among consumers and the financial sector, leading to cost- effective energy- efficiency measures opportunities being missed Limited know how of policy makers Lack of technical capacity to develop and implement energy efficiency projects Subsidised energy prices Organizational and institutional gaps and overlaps Limited access to capital may prevent energy- efficiency measures from being implemented Inertia: individuals who are opponents to change within an organisation may result in overlooking energy- efficiency measures that are cost- effective Policy interventions are re - to overcome such barriers

Options to Remove Barriers to Energy Efficiency Removing barriers to energy efficiency require different measures Minimum energy performance standards (MESP) and labeling Awareness- raising efforts Economic incentives Energy efficiency programmes and capacity building Energy service companies Energy Management systems Evaluation and impacts assessment are important -

Conclusion More measures need to be adopted and implemented to improve energy efficiency on the continent A large part of the potential is untapped as most countries relay on old and inefficient technologies (often acquired second- hand) The residential, service and industry sectors use more than 80% of the energy in African countries, making these sectors an obvious focus to implement measures to improve efficiency on the demand side Energy efficiency measures are also needed in the transmission and distribution system due to high technical and non- technical losses therein. -
