“It is a truth universally acknowledged,…”
“…that a single utility in possession of a sunk cost must be in want of a price cut.” (with apologies to Jane Austen)

“…that a good regulatory process must provide a reasonable prospect of cost recovery”

Procedural Standard
Revenue Standard
Regulatory systems evolve defences against opportunism (or they fail)
Constitutional Defences against Regulatory Opportunism:
A Procedural Standard allows scrutiny of decisions and hence enforcement of the Revenue Standard
Good decision-making
The right value

Benchmarking persists where procedural standards are weak
Weaknesses in the benchmarking process:
Problems with UK procedures and appeals:
Residual
“Inefficiency”No agreed model;
selection by results
Widespread acceptance of
regulatory discretion
Appeals judged on plausibility, not on objectivity
No cross-examination to
expose subjectivity
“Efficient Costs”
Correct standard
UK regulation has a weak “evolutionary engine”, which allows bad methods to persist (until now….?)

GB: Appeals against poor process were more effective than disputing values
“Limited Merits” Appeals against RIIO-ED1 (2015):
Northern Power Grid (distribution network operator)re: own price control1. Real Price Effects – unit prices rising faster/slower than RPI2. Regional labour cost adjustment – used in benchmarking3. Smart grid – implementation targets were baseless
Centrica (retail supplier and network user)re: price controls for all “slow-tracked” DNOs4. Cost of debt – too high5. Interruption incentive – too generous6. IQI – calibrated without reference to Ofgem’s stated objectives

The British appeals panel accepted regulatory discretion, but rejected arbitrary procedures

2013: Dutch regulator adopted a European DEA model, but adapted it:– Replaced (European) Post-Tax WACC with (Dutch) Pre-Tax WACC; and – constrained weights on variables (to get “stable” results)
These changes lowered TenneT’s score from 100% to 85%.– Mostly due to use of Pre-Tax WACC (NERA Sensitivities for TenneT)
TenneT appealed to the regulatory tribunal (CBb), twice:
2015 Judgement:
Add a margin of error for model selection
2016 Judgement:
5% is not enough:sensitivities => 10%!
NL: Dutch national grid challenged use of only one benchmarking model
The Dutch court required the regulator to allow for equally valid, alternative approaches
Dutch Court rejects single-model benchmarking:

Conclusion: Why regulatory procedure matters
Legal frameworks vary between jurisdictions, but in general regulatory appeals enforce the standards of good decision-making:
(1) Revenue Standards (if any); and (2) Procedural Standards
– Even in “Limited Merits Reviews”, (quasi-)judicial panels often focus on the procedures used to set values, not on the actual values
– Regulatory benchmarking overrides any Revenue Standard by ignoring the Procedural Standard, and only survives where procedural constraints are weak
Enforcing (“good”) regulatory procedure on individual choices prevents arbitrariness and opportunism (i.e. “bad” values)
Appeals over the Procedural Standard impose a useful discipline (good decisions), especially if the Revenue Standard
(the right value) is poorly defined
