CHALLENGES AND INVESTMENT OPPORUNITIES: THE CASE OF ZESA By Mr Ikhupuleng Dube, System Development Manager – Zimbabwe Electricity and Transmission Company (ZETDC), a subsidiary of ZESA Holdings (Pvt) Ltd Presented at the Worldbank CCS Workshop Johannesburg 31 st May– 1 st June 2011

Presentation Content Electricity Sector Policy, Governance Structure and Players Importance of Electricity in Promoting Economic Growth Current Challenges  Security of Supplies  Reliability of Supplies Investment Opportunities  Generation  Grid  Other

Electricity Sector Policies Ensure availability and accessibility of electricity to all consumers (current and future) at competitive prices; and Facilitate electricity investments and access by Independent Power Producers (IPPs), Public Private Partnerships (PPPs), Private Public Associations (PPAs) and other forms of joint ventures into the sector.

Electricity Subsector Structure

ZESA Holdings  Holds shares of the successor companies on behalf of the Government  Have four subsidiaries  Zimbabwe Power Company (ZPC)  Zimbabwe Electricity Transmission and Distribution Company (ZETDC)  Powertel  ZESA Enterprises

ZESA Main Mandate To supply all sectors of the economy with adequate, safe, reliable environmental friendly and least cost electrical energy. – Strong linkages between electricity supply and economic growth.

Reduced availability of Imports Challenges

Historical Trends of Electricity Import by ZESA (MW)

Factors Affecting Load Growth Suppressed demand due to load shedding (2591GWh in 2008) Investment due to large mining customers (almost 800MW in the medium term) Resuscitation of production levels by large users (currently suppressed demand of 340MW) Access to electricity by urban households (estimated at 60MW yearly for the next 15 years starting in the medium term) Rural electrification (total load of 420MW) General economic growth (linkages between productivity and energy consumption) Demand due to services such as public lighting, water pumping etc. Resuscitation of production levels in the agricultural sector. Increase in demand due to improved consumer lifestyles

Future Demand and Supply Balance

Availability Energy Resources to Meet Demand - Coal

Coal Policy Issues To ensure adequate and reliable supplies of coal in a cost effective and sustainable manner; To ensure environmentally friendly exploitation methods; To explore the techno-economic feasibility of new coal technologies such as coal gasification, carbon capture and coal-to-liquid conversion;

Availability of Energy Resources to Meet Demand - Hydro SiteCapacity (MW) Batoka Gorge1600 Devil's Gorge1240 Mupata Gorge1000 Small Hydro300

Other Available Energy Sources Coal bed Methane - estimated at more than 600 billion cubic metres (further exploration to confirm amount of gas). Forest residues - almost entirely based on plantation timber;70,000 tons of this biomass waste is produced annually. Energy Crops - in the next four years 150MW to be generated from energy crops.
