Ofgem has launched a consultation after ScottishPower raised payment claims regarding the Supplier of Last Resort (SoLR) process.
The company was appointed by the regulator to take to customers of Tonik Energy when it went bust in October last year.
On 29th October, ScottishPower gave notice to Ofgem of its intention to submit a claim for a Last Resort Supply Payment of up to £1.04 million.
The company claims additional costs incurred in acting as SoLR to customers of the former Tonik Energy.
ScottishPower is also seeking to claim payment of up to £2.4 million for additional costs incurred in acting as SoLR to customers of the former Daisy Energy Supply Limited, which traded under the name of Yorkshire Energy.
Ofgem, which said it is minded to consent to ScottishPower claiming Last Resort Supply Payments, aims to make a decision next month.
