Pully's electrical service is effective, with few interruptions, and ongoing monitoring via widespread
installation of household smart electricity meters. The average reported length of the interruptions
is somewhat high, though, at 512.88 minutes, which points to weather-related causes as a probable
reason. It is recommended that the city studies and confirms the factors behind its protracted average
outage time, and takes steps to reduce the time for each incident.

Optimizing Electrical Supply: Installation of household smart electricity meters and introduction of ICTs
to monitor its electrical supply systems will take place in Pully in keeping with a national law requiring
smart meters to be implemented by 2027. This will further help the city in reducing any interruptions
in electrical supply. Recommendations ITU-T Y.4000 to Y.4999: ‘Internet of things and smart cities and
communities’ contain guidance on IoT applications and ubiquitous sensor networking, including, for
example, Recommendation ITU-T Y.4409/Y.2070: ‘Requirements and architecture of the home energy
management system and home network services’.

The above will also enable the city to move towards, and take advantage of a more local distributed
energy resources (DER) market, which is gathering momentum through Europe as technology costs
come down. Developing this demand-response capability will be vital in keeping costs down in the
future by: providing load reductions during periods of extreme load; curtailing demand on overstretched
power generation capacity as a city’s population and economy grow; and helping to avoid unnecessary
investments in new grid capacity.
