Pan-European cost efficiency benchmarking of gas and electricity transmission system operators (TCB21)

Since 2003 the CEER has performed several cost efficiency benchmarks of electricity and gas transmission system operators (TSO(s)), the most recent being the CEER TSO Cost efficiency Benchmark 2018 (TCB18 ) study with reference year 2017 . Formally, each benchmark is procured by one of the national regulatory authorities (NRA(s)) on behalf of CEER .
