The significant gap between electricity supply and demand in South Africa, coupled with inclining power tariff increases, is compelling reasons for businesses to reduce electricity consumption. The good news is that energy cost reduction is relatively simple to achieve and can lead to significant improvements in bottom-line performance.
Energy consumes a significant portion of any organisation’s spending, accounting for 5 to 20 percent of a typical company’s costs. This is spiralling upwards as tariffs continue to increase into 2012 and companies must find ways of managing their electricity bills simply to ensure corporate sustainability. Equally compelling, however, is the motivation of ensuring a future for our country and its people.
Many organisations, however, have an awareness of their energy consumption and how to reduce it. They need to understand and actively manage their energy use – and their energy sources, including possible ways to produce their own energy. A comprehensive energy management strategy offers a number of potential advantages including significant savings, improved profitability, greater customer loyalty, a cost-edge over competitors, lower business risk and a company-wide awareness of sustainability that can rein in resource waste across the board.
Business must pay attention to energy efficiency
Cost savings, customer loyalty and sustainability all argue strongly in favour of active corporate energy strategies. But the most crucial spur for action in South Africa is the risk that a company’s operations could be disrupted by energy shortages, outages or escalating prices. The current realities of the electricity sector are therefore forcing business to re-evaluate energy consumption.
In addition, worldwide the trend is towards a greener future. If business does not adjust, it may not find many global markets in future as countries begin to demand environmentally friendly products.
Demand continues to outstrip supply
Decades of robust economic growth, low electricity prices and lack of investment in power generation in South Africa have placed our national electricity supply grid under severe pressure.
Electricity supply can hardly meet the growing demand for power. We have some of the cheapest electricity prices in the world as a result of artificial prices being set over the past few decades to attract foreign direct investment. We therefore use electricity more intensively than most other countries and our economic structure is now biased towards electricity- and capital-intensive industries.
This situation has become unsustainable and the country has to move towards cost-reflective tariffs.
Price increases
The move towards more sustainable electricity pricing is hitting business hard. The price of electricity is increasing by an overall 25% per annum between 2010 and 2012.
This effectively doubles electricity prices over three years, putting profit margins under considerable pressure. Already major energy-intensive organisations are feeling the pinch. Exxarro, for example, cites susceptibility of its zinc refinery operations to rising energy costs among its reasons for closing Zincor.
Business therefore needs to find ways of managing electricity usage before it seriously impacts profitability.
South Africa is taking energy reduction seriously
Government is committed to an aggressive low carbon trajectory and business will soon begin to feel regulatory pressure to become more energy-efficient. Incentives for reducing electricity consumption – and penalties for businesses that fail to do so – are looming.
Drivers for South Africa to reduce electricity consumption include:
Electricity supply security is critical for the country to facilitate economic growth. The costs of power outages are huge. For the government, subsidising energy efficiency or forcing companies to be more efficient is far less damaging to the economy than power disruptions.
Energy efficiency is often the least cost method of creating additional energy supply. The cost of building new capacity to generate 1Mwh can be far in excess of the cost of funding energy efficiency programmes to conserve the same amount of electricity.
The uptake of efficient technologies should assist in maintaining international competitiveness for local industries as global energy prices continue to climb. This is particularly true over the long term and for industries that must remain at the forefront of technology to remain competitive.
There is global focus on environmental protection, particularly climate change and the reduction of carbon emissions. Promoting energy efficiency can be a key tool for meeting our environmental goals and improving social welfare.
Sustainability. Effective energy efficiency will help prolong the life of finite non-renewable energy resources which remain a more cost-effective and reliable means of supply than renewable energy technologies.
Energy management is a global issue
Energy reduction is a global challenge and one that business in developed countries is taking very seriously.
According to the Deloitte resources 2011 US Study, 90% of companies have set goals regarding electricity and energy management practices. 76% have goals related to reducing electricity cost/consumption and 71% have goals targeted at improving the efficiency of the building in which they operate. These goals are significant, typically aiming for an average of 25% in electricity or cost reduction, most often with a 2–3 year time horizon.
56% of the companies have goals aimed at improving profitability through electricity reduction.
How can South African businesses achieve energy savings sustainably?
The time has come for companies to ensure they develop energy strategies. This is not about green-washing. Energy strategies are about hard-core business decisions; about going back to the basics of managing resources and resource use.
From better management of buildings and vehicle fleets, to smarter use of technology, to tighter oversight of their entire supply chain, organisations can mobilise countless tools to help transform how they use energy and other resources.
And companies can actively begin to analyse the potential to produce their own energy – from using their rooftops for solar, to land for windmills, to distributed forms of production, like micro-turbines.
Efficient management of energy consumption deliver real value by increasing revenue and decreasing costs, leading to improved profitability.
There are a number of initiatives that can help increase revenue. Demand reduction programmes, for example, allow energy users to voluntarily reduce demand at short notice and receive monetary compensation. Where appropriate, revenue can also be increased through the sale of excess energy production, and/or renewable energy certificates (RECs). This is a little understood market in South Africa but there are already 30 local projects registered with the UN for RECs.
Operational performance improvement, energy audits and supply-side cost reductions and lead to decreasing costs. Energy efficiency self-audits can determine if more efficient methods or technologies could be deployed to significantly reduce operating costs and create significant value for the company. Evaluation and negotiation of utility contracts to leverage lower rates or tariff opportunities can also lead to substantial savings.
