The Manx Electricity Authority owes more than ?400 million – and is paying more than ?15 million a year in interest charges alone.
The figures have been revealed in response to a question for written answer in the House of Keys.
Michael MHK Alf Cannan quizzed Treasury Minister Eddie Teare about interest payments on the debts – and who pays.
In response, Mr Teare said the ?15 million a year is being paid by the MEA, wiuth no government subsidy.
Mr Teare told the House each year the Authority pays just over ?2 million in interest to banks, ?10 million in government bonds and ?3 million on a BGE finance lease.
Those figures, he said, have remained largely unchanged over the past two years.
Mr Teare also revealed the MEA owes ?35 million to the bank, ?185 million in Treasury bonds, ?133 million to BGE Finance and ?47.5 million to Lombard Manx.
And he also pointed out all the information requested was contained in the MEA’s annual report from last year.
