The Commerce Commission has forced a South Canterbury electricity lines company to repay $16.9 million to consumers for overcharging.
The regulator warned Timaru-based Alpine Energy over an accounting mistake that saw it give the Commission incorrect information.
The Commission allowed Alpine to charge customers higher prices on the basis of the incorrect information between 2015-24.
Commissioner Vari McWha said the mistakes were not intentional, but were serious and preventable.
"We're mindful that, given electricity is an essential service, consumers may have suffered unnecessary hardship as a result of this error," McWha said.
She said Alpine lowered its pricing and had given credits to customers, put money aside for former customers and established funds to improve electricity access in the community.
"That's why, in addition to paying customers back the amount they are owed, we have secured a commitment from Alpine to spend at least $1.5 million to support access to electricity in the local South Canterbury community."
Alpine was also issued with a formal warning.
The Commission said Alpine adjusted its prices from June 2024 and refunds would be delivered by crediting the accounts of current customers.
There would also be a programme to make payments to former customers, who can show they were eligible for a refund.
