The potential for a robust global climate deal at the Paris Climate Summit in December 2015 is driving an increased emphasis on renewables and clean tech in the next five years according to energy companies surveyed in PwC's new global power and utilities survey.

PWC said that evaluating the classic energy trilemma between security, affordability and sustainability, survey respondents appear to anticipating a more robust climate deal than has been achieved before – with sustainability/cleaner energy moving up from 61% of their focus in the trilemma now to 81% in just five years.

Security of supply remains the foremost priority, with the shift in focus towards sustainability largely at the expense of affordability. This emphasis change is biggest in South America  a move from 54% to 83%and smallest in Asia Pacific – 55% to 66%.

The report also finds that power utilities businesses around the world are reporting a difficult transition as energy transformation takes hold with increased concern about immediate risks to the power system as well as challenges adjusting to longer-term changes.

In the short-term period to 2020, concerns about nearly all of the major risks facing the power sector are rising.  Alongside the leading risks of regulatory uncertainty and the difficulties of attracting investment, companies are moving to high alert on other key risks:

• Sophisticated cyberattack – 75% concerned for 2020, up from 40% now
• Fuel availability/supply risk – 77% expect this to be a moderate to very high concern in 2020, up from 66% in 2015.
• Blackouts – 74% concerned for 2020, up from 68% now.
• Emissions/air pollution - 75% concerned for 2020, up from 53% now.

43% of respondents in North America and 35% in Europe say that current power sector company business models are already broken and the need for change is already urgent.

Norbert Schwieters, global power and utilities leader, PwC, said:

“Looking ahead, we think predictions of a ‘death spiral’ for companies in the power and utilities sector are overdone. But, the dangers facing the sector are intensifying and companies will need to stay ahead of change. The challenge will be to make timely moves to gain the most of the market opportunity of ‘old energy’ systems and business models while, at the same time, transitioning to the new business models required as energy transformation takes hold.”

“Areas that are of limited or only emerging importance to the sector at the moment, such as smart city, smart home and smart community infrastructure, local energy systems, electric vehicles and off-grid solutions, will become increasingly important alongside an increased emphasis on capabilities such as product innovation, big data platforms, digitisation and online security.”

The report also includes a new Power & Utilities Market Disruption Index, based on survey respondents’ assessment of disruption in five key areas. At a global level, the index rises by 42% between 2015 and 2020, with Europe remaining the most disrupted region in 2020.

Norbert Schwieters added:

“Market and new competitive disruption is gathering pace in power markets around the world and it’s expected to intensify in the next five years. Less than one in three said their market is relatively undisrupted now but hardly any expect that situation to continue to be the case by 2020. It’s arising from a combination of policy, technological and customer change and creating a transformation in how we think about, produce and use electricity.”
