InnoWind is proposing to both the Basic Assessment and EIA pro- establish four commercial wind energy cesses currently being conducted by CSIR on projects near the towns of Swellendam, behalf of InnoWind.

The InnoWind NEED FOR THE PROJECT project is being developed in two phases: The intention of this project is to generate Phase 1 includes one temporary wind additional electricity that will feed into the monitoring mast (except Mossel Bay which national grid by installing 4 wind farms with will have two) and a single turbine of a maximum capacity of between 18 and 132 approximately 2.3 to 3 MW at each site (i.e. MW per farm. At a national level, renewable 5 masts and 4 turbines in total), which is the energy has the potential to play an impor- focus of a Basic Assessment Process with the tant role in South Africa through diversifying following DEA Reference numbers allocated the sources of power generation and to the project: reducing the carbon footprint from fossil fuel power generation, such as coal fired Swellendam: 12/12/20/1773; Heidelberg: power stations.

The favourable renew- able energy feed-in tariffs released by government in April 2009 provide an February 2010 Background Information Document for InnoWind Western Cape Wind Project important catalyst to promote the use of wind energy in South Africa. Hub In terms of resource-use, wind energy offers Nacelle significant advantages. Coal-based energy requires significant water input to generate electricity, while also producing vast amounts of CO2 . Wind energy on the other hand, requires no water input and Rotor blade generates no CO2 emissions during operation. South Africa's labour market will also be positively influ- enced by wind energy development, with the procurement of various local sub-contractors during the construction phase, and the creation of perma- nent and temporary jobs as part of the development of this emerging industry. The Western Cape Province produce approximately Hub height ~ 100 m 31 million tons of carbon dioxide (CO2 ) per year. Tower Electricity generation is responsible for roughly half of this figure. In the light of the Western Cape being one of the worst affected provinces in terms of climate change, the Western Cape Provincial Government recently announced that reliance on fossil fuel-based energy sources is no longer a solution to the province's energy security and air quality challenges. Accordingly, the Western Cape A single pilot turbine (with a maximum of 3 MW aims to improve energy efficiency by 15% by 2014 capacity) is also proposed to be erected within the and 20% by 2020.
