  • 80% of respondents say business interruption will become more important
  • Strategic risk underpinned by rise of digital and changing customer expectations
  • Regulatory change expected to become more significant in a new energy world

Business interruption due to storms, catastrophic events and cyber attack present the biggest threat to power and utilities (P&U) companies, according to a new EY report, Risk Pulse: Navigating the power and utilities sector in transformation, which ranks the strategic, financial, operational and compliance risks across the sector. Managing traditional risks such as cost recovery of regulatory assets also remains high on the agenda for utilities worldwide.

Increasingly turbulent hurricane seasons, sweeping power outages and numerous distributed denial-of-service attacks are just some of the disruptive forces that have shaken utility operations in recent times. As the frequency of catastrophic events accelerates, resilience and business continuity are being tested across the sector, with 80% of respondents indicating that business interruption will become more or much more important in the future.

With top risks expected to become more important only as the sector transitions to a new, digitized energy world, the findings highlight the need for companies to implement effective response strategies to enable the future utility.

Matt Chambers, EY Global Power & Utilities Risk & Cybersecurity Leader, says:

“Utilities need to ask themselves whether their operating model is agile enough to react to unexpected events as they unfold, and whether they have the right resiliency to recover. This is further compounded by the rising importance of data privacy and protection, which demands that companies place greater emphasis on cybersecurity as an enterprise priority.”

New technologies and changing customer demand are top strategic risks

The survey finds that the top strategic risks are underpinned by the rise of digital and the customer response to the changing energy landscape.

The rise of distributed energy resources (DERs) is respondents’ number one strategic risk and third highest overall risk, as greater DER integration places pressure on traditional sales and the customer relationship. With distributed generation and emerging technologies offering consumers more choice, changing customer demand and expectations is the number two strategic risk as non-traditional market entrants make inroads – placing further pressure on revenues. This trend is underscored by the evolution of digital technologies and the Internet of Things (IoT) – the third highest ranked strategic risk – as companies respond to the speed of change and associated security risk.

Chambers says: “Risk management will evolve in exciting new ways as enabling technologies, like robotic process automation, blockchain and data analytics are increasingly deployed to increase efficiencies, reduce costs and improve performance. Utilities will need to monitor the digital landscape and innovate in order to remain relevant and succeed in a future energy world.”

Regulatory compact under increasing strain

Regulatory or rate changes impacting cost recovery of assets ranks as the number one financial risk and second-highest overall risk, with 55% of respondents anticipating that this risk will become more or much more important in a new energy world.

The survey highlights that regulatory frameworks still incentivize network expansion but do not necessarily provide the right financial incentives to encourage utilities to invest in innovation and digital technologies, including distributed generation.

About the report

Change within the P&U industry is coming fast and furious. Many utilities tell us they’re worried about whether they’ll be here in 10 or even 5 years’ time. How will they navigate both today’s risks and the long-term risks of a future energy world? How prepared are they to weather the storm? The answers to these questions may determine whether they thrive or even survive a decade from now. To help utilities identify top risks, EY has developed a Risk Pulse report. It explores the risks that utilities are prioritizing now, what strategies they have in place to mitigate such risks, and how they expect these risks to change as we transition to a future energy world.
