With the UK now just hours away from departing the EU, Utility Week explores what this means for the utilities sector. How will energy collaboration with Europe proceed, and what does this mean for decarbonisation of the grid? Will there be an impact on the efficiency of interconnectors? Will the UK continue to trade in the EU Emissions Trading System? David Blackman discusses these and other issues.

With expanding AI capabilities, industries such as the energy, rail and telecommunications are witnessing growth in the adoption of UAVs (Unmanned Aerial Vehicles, or drones). The increase in drone usage has already begun challenging the conventional methods of inspection and maintenance of assets. More importantly, it is showing the value of using innovation to overcome traditional challenges.

Interconnector capacity between England and Scotland must be quadrupled over the next decade to match up growing supply north of the border to where demand is greatest, a former energy minister has warned. Charles Hendry, who was minister of state for energy from 2010 to 2012, warned the UK and Scottish governments they must develop a much more “common” approach to energy.
