PUN and PSV, week 41 of 2026

The week from 5 to 11 October 2026

The PUN rises by almost 8%, along with gas: the wind returns, but water falls short

Electricity

From 5 to 11 October the PUN Index GME rose again: on average €217/MWh, almost 8% more than the previous week (GME, weekly results, PDF in Italian). The wind came back, and wind energy sold more than doubled; but hydroelectric power fell by about a fifth and solar by more than a tenth, so renewables as a whole went down. Gas-fired plants sold about a tenth more, with gas more expensive: both peak hours and the others went up. In the North and Centre-North zones the price was higher than in the rest of Italy.

Gas

Gas on the GME day-ahead market (MGP-GAS), delivered at the PSV, the virtual trading point, rose again after two weeks of decline: on average €80/MWh in continuous trading, more than 7% above the previous week (GME, weekly results, PDF in Italian). This time electricity and gas moved together.

What to watch that week

For anyone thinking of switching electricity supplier: under the current procedure requests can be sent until 10 November, and from 1 December the switch can take effect on any day of the month (ARERA, resolution 58/2026/R/eel, in Italian; what changes for a business, in the guide). For energy-intensive and gas-intensive companies, the CSEA portal for the 2027 lists stays open until 16 November.
