Continued growth of distributed energy resources and energy efficiency measures could cause significant demand disruption and drive down utilities revenues by up to $48 billion a year in the United States and 61 billion a year in Europe by 2025, according to Accentures Digitally Enabled Grid research.
Accenture performed extensive modelling under three scenarios to assess how technologies, such as solar photovoltaics (PV), electricity storage, electrification of heating and transport, energy efficiency, energy conservation and demand response, would impact the grid network and utilities business models.
Additionally, as part of the research, Accenture conducted its second annual survey of global utilities executives and found that perceptions of the impact of these energy demand-disrupting technologies have shifted considerably in the last year. Utilities executives are notably more concerned about the impact of these technologies on future revenue streams, with 61 percent saying that they expect significant or moderate revenue reductions as a result of distributed generation, such as solar PV, compared to 43 percent last year.
Based on our research, Accenture believes that the most likely scenario in the next 10 years could lead to revenue losses at the lower end of our scale, $18 billion a year in the U.S. and 39 billion in Europe, caused by a moderate reduction in load on the grid network, said Valentin de Miguel, global managing director of Accenture Smart Grid Services. This is because adoption of energy efficiency and distributed generation will become possible without subsidies, which will lead to greater market penetration as a result of shifting consumer sentiment, falling technology costs and a moderate rise in electricity prices, especially across Europe.
Despite popular reports of a looming utilities death spiral, in which consumers migrate off the grid or use it only as backup, Accenture research shows it to be unlikely and uneconomic for a large number of consumers due to natural limitations on viability and cost constraints.
The vast majority (79 percent) of utilities executives believe that it wont be cost-effective for consumers to go off-grid without any subsidies until 2030 or beyond. In addition, by 2035, just 12 percent of customers in North America are expected to become energy self-sufficient, compared to 11 percent in Europe.
Solar PV is already at grid parity equal to or less than the cost of power purchased from the grid in many states in the U.S. Accentures analysis suggests that by next year it will be at grid parity across Australia and most EU member states, except less sunny ones like Sweden and Poland, and Spain, where there are regulatory barriers to solar PV deployment. Japan will reach parity in the next few years, followed by the rest of North America, with the exception of Canada and some U.S. states with the lowest electricity prices.
While the death spiral, as commonly defined, is a myth, the demand disruption caused by the growing adoption of energy demand-disrupting technologies is a very real threat to utilities business models, added de Miguel. And in addition to the financial pressure, this will cause significant operational challenges for utilities, increase technical stress on the grid and open the market to new competition for energy products and services.
Nearly two-thirds (61 percent) of utilities executives expect grid faults to increase by 2020 as a result of low-voltage connected distributed renewable generation up from 41 percent last year. More than half (53 percent) also expect an increase in grid faults from deployments of large-scale renewables also up from last year (33 percent).
A significant majority of utilities executives expect continued competition from new entrants in data-related services (92 percent), distributed generation (87 percent) and beyond-the-meter energy efficiency and demand response solutions (90 percent), as well as in a number of new areas, such as plug-in electric vehicles (PEVs) and associated charging infrastructure (81 percent).
In order to navigate through this demand disruption, utilities will need to fundamentally transform their business models, including the creation of distribution system operations services to manage a more complex and distributed grid, said de Miguel. As part of this transformation, they should focus on engaging with regulators to secure the long-term viability of the distribution business. This includes the adoption of new tariff structures, opening up new markets and aligning subsidies; investing in grid optimisation, such as automation, sensing devices and real-time analytics; and developing new customer products and services.
