Longer view shows excessive profits for electricity distributors
Dr Geoff Bertram looks beyond the Electricity Price Review's five years of data to find evidence of excessive profit-taking by electricity network companies.
The first report from the Electricity Price Review, set up by Energy Minister Megan Woods in April this year, declares that, after "a comprehensive analysis of existing data sources", there is "nothing to suggest distributors are making excessive profits".
This claim must have startled most electricity consumers, after three decades of rising prices, high profits, and massive capital gains for network owners.
There is no lack of data – since the 1960s, financial statements for each network have been published annually on the public record.
Serious research into profitability would surely span the three decades since electricity supply authorities had their assets expropriated by act of Parliament, were transformed into corporatised monopolies, were then left unregulated for a decade, and finally became "regulated monopolies" in 2008.
Inexplicably, the price review looked at only the past five years of data, from 2013 to 2017. During that period the electricity network companies collected just enough revenue to give them a commercial return on the value of their assets, as determined by the Commerce Commission.
The price review asked whether the sector's profits represented a commercial return on the asset values set by the commission. Finding that the answer was yes, the review announced "no excess profits". But what is this "regulatory asset value" against which profits are evaluated, and why did the price review not look back before 2013?
Consider the Wellington and Hutt electricity networks. Back in the early 1990s, electricity customers paid those networks about $55 million a year. Of that, $40m went to pay for operating costs, and $14 million was invested in new network assets.
Effectively, all the money paid by users was ploughed back directly into the service.
Fast-forward to the five years 2013-17. Excluding Transpower charges, users paid $115m a year for the same network services. Operating costs were $29m a year. Capital spending averaged $33m a year.
Just half the money collected from users was ploughed back into operating costs and new investment – $2.7m a year went to pay tax; the other $51m went as clear returns to investors after covering all operating costs, capital expenditures and tax payments. Excessive seems a reasonable description.
Corporatisation and privatisation
Back in the early 1990s, the government promised, first, that corporatisation and privatisation would bring costs down and, second, that cost reductions would pass through to lower prices. Instead, as operating costs were driven down, prices went up, sending margins through the roof.
If the old supply authorities had continued unchanged, even with no average-cost savings at all, and if their capital spending had been equal to the actual figures, then over the past five years network charges would have been $83m a year – not $115m.
Monopolists routinely put a value on their assets for accounting purposes. Turned loose to price-gouge their captive customers after 1994, the owners of the Wellington-Hutt networks were sitting on a gold mine.
Network operations with a historic-cost value of $127m were bought by TransAlta NZ for $320m, then sold to United Networks in 1998 for $590m. In 2008 the networks went to another eager buyer, Wellington Electricity Distribution Network, for $785m.
The non-current assets are now valued on that company's books at $881m, of which $256m is "goodwill" – an accountants' expression that means, in this case, monopoly power exercised to extract profits from customers.
Writing up assets, obviously enough, reduces the apparent rate of profit. That's the trick the Commerce Commission signed off when it established its "regulatory asset base". That's why the commission's regulatory accounts for 2013-17 don't reveal any "excess profits". The smoking gun lies buried under a mountain of asset revaluations.
Sting in the tail of this story
Connoisseurs of tax avoidance will enjoy the sting in the tail of this story.
In 2017, Wellington Electricity reported an after-tax loss of $3m on revenues (this time including Transpower charges passed through) of $195m, with operating costs (again inclusive of Transpower charges) of $106m, leaving a gross margin (ebitda), after some minor items, of $84m. "Depreciation and amortisation" took $32m of this, tax took $3.7m, and "finance costs" took $50m.
The company's debt at the end of 2017 was $722m – 123 per cent of the book value of fixed assets. Of this debt, $234.5m was owed to a related party in Hong Kong at an interest rate of 8.75 per cent.
Last May, the Australian Tax Office won a landmark court case against Chevron Australia, which had used a similar related-party loan arrangement to transfer excess profits out of Australia and thus avoid paying tax.
Time perhaps for Inland Revenue to check the tax accounts of Wellington Electricity? Certainly time for the price review team to take a more serious look at all the data – not just those sanitised five years.
