WIND AND RENEWABLE ENERGY
Integrating Wind and Hybrid
Generation for Energy Security
SA Cities Network Spier 14 May 2008
Realising Africa’s clean energy potential
Bulk generation technologies
Challenge is to think creatively and develop new
partnerships
1. Wind is relatively quick and easy to deploy 2. Options for bulk renewable and clean energy
projects - wind, wave, solar, bio-energy – provide reliable power, save resources and defer capital costs
3. BUT …….
1. Over come the technical challenges such
as intermittency fear
2. PPA and credit ratings of Municipalities 3. New MW scale storage options
4. Solution – integrated utilities that deliver across
multiple technologies

Realising Africa’s clean energy potential
National wind monitoring and preliminary assessment conducted by the
SA Wind Energy Programme (UNDP/DBSA/GEF/DME) suggests substantial
resources to be harvested in the greater East London area

Wind Energy – a powerful under-utilised resource
Realising Africa’s clean energy potential
Wind Energy Converter Technology worldwide
Maturity
1. technology is proven worldwide 2. 36000 MW installed world wide 3. industry growing at 23 % p.a
4. early turbines 120kW – now turbines of 4,5MW
5. gearless turbines entering the market
Reliability
1.
high level of reliability internationally2. availability of up to 98% (Zafarana, Egypt) with high efficiencies in good wind regimes
3. full automation with remote access diagnostics and control on each turbine
4. turbines show high dependability in a range of circumstances
5. auto-shutdown to prevent fatal failures – safety features
Wind Energy Converters are a mature
technology
deployed across Europe,
USA, India, Africa, China – rapidly growing market
1. Germany: 14,609 MW
2. U.S.: 6374 MW
3. Spain: 6202 MW
4. Denmark: 3110 MW
5. India: 2110 MW
Benefits to the Municipality
Wind energy, complemented by other energy technologies, will provide a
number of benefits to a Municipality
Wind energy, complemented by other energy technologies, will provide a
number of benefits to a Municipality
1. The project will demonstrate leadership and service
delivery through implementation
2. Support city clean energy vision – leadership,
innovation, foresight
3. Diversifying the mix - energy security
4. Leader in South Africa in implementing commercial scale renewable energy projects
5. Development and training of graduate engineers
through exchange & internship programme
6. Establishment of local O&M capability – job creation, investment
7. Foundations for a longer term RE industry – phased in
manufacture & assembly of turbines possible
