Last year, ACM commissioned Oxera to conduct a study on dynamic efficiency for Dutch transmission system operators (TSOs). The objective of the study was to advise on the scope of productivity improvement that an efficient TSO could achieve over a regulatory period due to technological improvement (also referred to as ‘frontier shift’) or cheaper inputs. In particular, the aim of the analysis was to produce productivity growth estimates using Total Factor Productivity (TFP) and Output Price Index (OPI) measures, to be applied over the regulatory period starting in 2017 for TenneT (the electricity transmission operator) and Gasunie Transport Services (GTS) (the gas transmission operator).
