How SMEG Kept Monaco's Grid Stable Through a Brutal Summer
By Zak Jackson, MonacoViews Editorial
Monaco's electricity network faced its toughest seasonal test yet as record heat and storms put the SMEG grid under sustained pressure throughout summer 2026.
A summer of intense heat waves and violent storms pushed Monaco's electrical infrastructure to its limits, with the Société Monégasque de l'Electricité et du Gaz working through the season to prevent outages across the Principality. SMEG engineers maintained close surveillance of the network as demand repeatedly spiked during the hottest periods, when air conditioning loads across residential towers, hotels and commercial buildings placed unusually high strain on supply lines.
Monaco's grid is rated among the most reliable in Europe, but SMEG has been candid that no network is immune to disruption when extreme weather combines with peak demand. The organisation deployed additional monitoring protocols this summer and coordinated contingency capacity to reduce the risk of localised failures, particularly in high-density districts where an outage would affect large numbers of residents simultaneously.
The broader pattern is one that Monaco's infrastructure managers are increasingly planning around. Storms that once arrived seasonally are now more frequent and more severe, and heat events that would have been exceptional a decade ago are becoming routine. For property owners and residents, SMEG's ability to hold the line this summer offers reassurance, but the experience has also underlined the long-term investment that keeping the Principality powered will require.
