Pas de déploiement industriel prévu

• Test of targeted power curtailment as an alternative to load sheddings based on reduced break-up power at the Linky meter level: 22 tests performed across approx. 300 voluntary households, with prior day-ahead notification and same-day SMS notification.

Further development

needed before roll out

• Formalising customers’ consent for data collection and their availability on “Enedis Data Connect”: setting up a portal to display individual consumption data.

• Improvement of the “Enedis à mes côtés” app.

• Daily consumption data (individual or aggregated) on various scales for local authorities: “Ti-Solenn” energy demand management platform for individual “coaching” and citizen outreach.

Grid-wide roll out ongoing

ACHIEVEMENTS AND LESSONS LEARNED

• Help customers individually manage their power consumption.

• Test targeted power curtailment to lower outage risks generated by grid constraints.

• Provide local authorities with better insight into local energy use through aggregated consumption data from the Linky system.

• Carry out a social survey on customer acceptance regarding new grid securing functions.

OBJECTIVES

1000 residential customers, 10 000 households with Linky smart meter.

• Real effects on the grids require a reduction of break up power by at least 50% (based on simulations) .

• Good public acceptance of the program conditioned to precise information being provided during test periods and limiting the number of tests carried out within one single period.

• Targeted curtailment closely linked to temperature variations, as showed by increased amount of breakers opening during coldest day in the period.

• Re-closing of breakers happened within less than 3 minutes on average, which testifies about high levels of understanding of the scheme across households.
