Employees at the National Energy System Operator (Neso) believed their concerns about potential electricity blackouts were not being taken seriously by senior management, according to an independent investigation into the organisation’s handling of warnings during Britain’s summer heatwaves.
The report, published on Monday, found that some staff perceived their concerns were being overlooked because of pressure to keep external stakeholders, including the Government, customers and regulators, satisfied.
The investigation was commissioned by Neso after whistleblowers raised allegations that the organisation had attempted to conceal how close Britain came to experiencing blackouts during periods of extreme summer heat.
At the time, Energy Minister Michael Shanks maintained that electricity supplies remained sufficient and that no customers had lost power.
Staff Perceived a Culture of Ignored Concerns
Investigators found that employees’ concerns about potential power shortages had, in their view, gone largely unheard because of what they described as the need to keep external stakeholders happy.
The report said this perception had contributed to a “culture of perceived non-response”, in which employees became reluctant to raise concerns because they believed doing so would not lead to meaningful changes.
It added that this perception represented a cultural and governance concern and helped explain why some individuals felt compelled to raise their concerns outside the organisation.
The investigators also documented an incident involving an official in the control room who was dealing with questions from external stakeholders about when alerts warning of potential shortages in the electricity system would be issued.
According to the report, a witness told the official not to feel pressured by those questioning the timing of the alerts.
The witness later advised the official not to allow the Department for Energy Security and Net Zero (DESNZ) to exert pressure.
Report Does Not Substantiate Allegations Against Management
Despite documenting employees’ perceptions, the independent investigation concluded that the allegations against Neso were not supported by the weight of the evidence.
The report did not establish that senior managers had deliberately sidelined concerns to satisfy the Government.
Instead, it identified a perception among employees that their concerns were not receiving sufficient attention, which contributed to some whistleblowers taking their complaints outside the organisation.
A separate preliminary review by energy regulator Ofgem also found that electricity supplies had not fallen below acceptable levels during the period under examination.
Neso was established as a government body under former energy secretary Ed Miliband and is responsible for managing Britain’s electricity system.
Conservatives Question Neso’s Management and Independence
Shadow Energy Secretary Andrew Bowie said the findings raised further questions about the organisation’s management, culture and operational independence.
He argued that the report had not fully addressed concerns about the body responsible for ensuring Britain’s electricity supply remained secure.
Bowie also criticised the Government’s net zero transition, claiming that greater reliance on renewable energy sources was making it more difficult to maintain the stability of the electricity grid because of reduced flexibility and inertia in the system.
He said the Conservatives had consistently raised concerns about the challenges associated with maintaining grid stability as the country moves towards its net zero targets.
Energy Minister Calls for Immediate Improvements
Michael Shanks said the independent investigation had found that the allegations could not be substantiated by the available evidence.
He also pointed to Ofgem’s review, which concluded that the electricity system had continued operating and customer demand had been met throughout the summer.
However, the minister acknowledged that the independent investigation had identified areas where Neso needed to improve its internal culture.
Shanks said the Government expected significant action to address the issues without delay and would monitor progress closely.
Britain Ranks 41st in Global Energy Security Study
The findings emerged as separate research published on Monday placed Britain 41st among 187 countries assessed for energy security.
The study, conducted by the Adam Smith Institute think tank, ranked Britain behind the United States, Canada, France and Japan among the G7 group of major economies.
Globally, Britain also ranked below several lower-income countries, including Romania, Azerbaijan, Serbia and Ukraine.
The research highlighted Britain’s position in the international energy security rankings as scrutiny continued over the management of the country’s electricity system and the concerns raised by Neso employees.
