A new benchmark assessment of European transmission system operators (TSOs) sets Denmark's Energinet in the elite category in terms of electrical grid management.
Fine results speak for themselves. As if it weren’t adequately commendable that Denmark’s national power is already heavily loaded with renewable electricity, transmission is also managed in a highly cost-efficient way, writes EnergyWatch.
That’s the conclusion of the latest benchmark report on European TSOs. Here, Energinet scores an entire 100 per cent in the electrical category and thereby makes it to the very top of the list along with seven out of 17 participant TSOs.
“It is important for us, not only at Energinet but for the whole of Denmark, that the electrical and gas systems are efficiently driven. To put it simply, ensuring security of supply and incorporating large volumes of renewable energy are challenging – but the real difficulty lies in doing both things at the same time, and efficiently at that, so consumers’ bills remain as low a possible. These results underline that we’re on the right track,” said Energinet Chief Executive Thomas Egebo in a press statement.

Potential efficiency gains in gas management
There is less to celebrate in terms of gas grid management, however. Energinet scores 88.1 percent, which is lower than its result from the preceding benchmark report from 2014 regarding gas, wherein the Danish TSO scored full marks with 100 per cent. The present result, though, is still above the European gas category average of 79 percent. Here, 29 TSOs took part.
“The European comparative analysis shows that Energinet’s electrical grid operation is ranked at the top, while concerning gas, [the report] indicates the potential for efficiency gains,” says Danish Utility Regulator Director Carsten Smidt in a press statement (in Danish).

“I’m pleased that we can show the Danes that the electricity and gas transmission networks are operated efficiently, so that private consumers get low tariffs and companies thereby get competitive conditions. As we have to integrate much more green electricity, which often comes as the wind blows, and get large amounts of biogas on the gas grid, this will not be a less important task – on the contrary, said Thomas Egebo.
The report assessed the TSOs based on the number kilometres of suspension lines, cables, masts, transformers, fields, reactors etc., as well as gas pipeline length in kilometers, meter stations, expense data and operating costs. Secondary factors included geography, policy, staff remuneration and related items, all of which were included to correct for national differences between the TSOs.
The analysis was conducted by consultancy Sumicsid on behalf of the Council of European Energy Regulators (CEER).
