The zonal energy pricing row has continued, with Centrica boss Chris O'Shea warning backers of the scheme are expecting "mass migration to windy places".
The proposed pricing shake-up, which would see the UK split into 12 zones with different bill levels based on proximity to energy sources, is being vocally backed by Octopus Energy.
Octopus boss Greg Jackson is against building windfarms off Scotland's coast where aging cabling infrastructure struggles to cope with increased energy transmission.
Octopus argues zonal pricing would "create economic growth potential in places like Scotland where new energy-intensive industries – such as data centres – could locate and benefit from some of Europe’s cheapest electricity".
But Chris O'Shea, the boss of British Gas owner Centrica, has taken aim at zonal pricing - and at Octopus.
Posting on LinkedIn, he said warned a zonal system, left unchecked, could become a "postcode lottery of energy prices".
He went on: "The idea that business will relocate to remote areas because energy is cheaper may not be realistic.
"They won’t go unless they can get the staff. Will people move before the jobs are there? And if both these unlikely events happen, what about the cost of the infrastructure which will be required such as the houses, the roads, the schools, the clinics, the hospitals etc.?
"Will that be available in good time? If so, will it really be cheaper than simply having a bigger and better grid?
"Curtailment costs are a problem-that is undisputed. One which could be solved by amending the cfd regime so producers don’t get paid for a product people don’t want to buy.
"Or, even better, we could build more energy storage. Would that not be simpler than expecting mass migration to windy places?
"We need a proper, well informed debate on this with all of the facts, and we can’t have a company masquerading as an insurgent pushing its own agenda. We need to approach this from the position of what’s good for the consumer, not what’s good for energy companies."
