Nearly all electric utilities claim climate change is threatening power outages, higher costs and changes in usage as demand grows to power the world's expanding cities.

This is according to an Acclimatise global report, backed by IBM. It reports that more than 90% of global electric utilities that report climate change activity to the Carbon Disclosure Project recognised they are at risk from changes in climate and water availability, which are already adding stress to the sector.  
However, fewer than a third claimed to undertake any financial or quantified evaluation to the impact of climate change on their business.
The report suggests the energy industry is rapidly approaching a critical stage of development. As demand is growing from new requirements such as electric vehicles, increased cooling during warmer summer months and rapid urbanisation, utilities need to attract new financial investment to grow existing capabilities and develop emerging technologies in a low-carbon way.
The report, “Global Electric Utilities – The Adaptation Challenge”, is based on 219 responses to the Carbon Disclosure Project's annual request for investor information from the industry, analysed using the Acclimatisation Index Methodology.
Other key findings include:
* While responding companies seem to have incorporated climate change in general into their governance structures, only a few electric utilities (6%) refer to adaptation directly as an integrated element of their governance, reporting and lobbying practices;
* 48% report to manage their climate risks, however adaptation actions are generally isolated and rarely form part of climate risk management strategies;
* 31% percent provide evidence of their climate change risks; and
* Compared to identifying climate risks (93%), far fewer electric utilities report that they recognise the opportunities of changing climatic conditions (59%).
"Risk management and adaptation planning are crucial to business success as climate change is directly affecting the generation, transmission and consumption of electricity,” said Graham Butler, Utilities Sector Lead, IBM Global Business Services UK & Ireland, "The smart electricity company of the future needs to have a fully integrated approach to building resilience. Business leaders will need the ability to gather and mine vast amounts of operational information to make accurate, smarter decisions to face climate change successfully and profitably."
Many scientists report that climate change is underway and the direct effects of increasing global temperatures, such as changes in precipitation and rising sea levels, are becoming more evident. Climatic issues have the potential to impact how all major electric utilities operate, underpinning the world's major cities, transport and water infrastructures, which are essential to the commercial world and the way we live.
Key challenges the electricity industry faces due to environmental changes includes:
* Impact of power outages: Outages caused by the weather can result in failure in the supply of power. Interruptions and longer term outages can cause major financial losses for utilities and the customers that depend on the service.
* Damage to operational performance: Extreme weather events and incremental change impact the bottom line of electric utilities by degrading site conditions, damaging assets, decreasing efficiencies of operations, reducing availability and quality of raw materials and natural resources. These events can also disrupt energy supplies which can then increase energy prices.
* Increased demand from urbanisation: The trend toward increasing urbanisation is expected to be accelerated as people move from rural areas. Electricity companies will face major challenges in providing new generation capacity and supply reliability within urban areas to meet the increased demands from domestic customers.
* Stress on water resources: Changes to the weather and an increasing population is placing global fresh water resources under increasing stress. Less water, declining water quality, and growing water demand are creating immense challenges to the electricity sector which is a major user of water. Delivering and treating clean drinking water, combined with providing safe sewerage and waste water treatment systems to an increasing global urban population will create significant increases in the demand for electricity. The impacts of climate change will also increase the competition for water resources among the electricity sector and other users for example, agriculture, fisheries, drinking water, industry and natural habitats.
As the impacts of climate change become more direct, governments are starting to resort to prescriptive regulation and statutory controls to ensure that electricity companies take appropriate action on climate change adaptation.
The issue of cost is also an important factor. For example, operational costs could increase in response to changes in equipment efficiency under higher temperatures, lower air pressure and modified humidity. Changes in security and quality of water supplies used for cooling will also have significant cost implications for water-intensive thermoelectric generating facilities.
Due to the increasing legislation and cost implications stakeholders that include investors, lenders, insurers, market and financial analysts, governments and regulatory agencies, consumers, local communities and NGOs are already starting to place greater pressure on electricity companies to address climate change risks and opportunities. If plans for expansion are to be achieved, stakeholders and increased investment are crucial to the development of the global electricity industry.
