Nice – IRIS Smart Cities Showcase

IRIS Nice Côte d’Azur: Transforming into sustainable districts

In Nice, we develop energy neutral districts deploying renewables and electric mobility solutions.
A digital marketplace for mobility, energy and environmental data fosters innovative applications and empowers suppliers and citizens to be proactive about their sustainability.

Featured Solutions

Collective self-consumption at building scale

Collective self-consumption at building scale is a new concept for commercial and residential customers in France while only a small number of projects have been done in Europe so far. This concept will be tested in Nice Meridia on two positive energy buildings, IMREDD and PALAZZO.

Optimization of social housing heating

Social housing managers Cote d’Azur Habitat and Engie Cofely have teamed up to test a system of intelligent management of heating in two recently renovated towers. These buildings, equipped with high inertia system underfloor heating, will permit optimal meteorological regulation testing and adjust the temperature for each flat.

Smart charging of a city owned EV-fleet

Low-carbon mobility is one of the main development pillars of the Metropolitan authority, an early adopter of EV-mobility solutions. Nice will become the first public authority in France to test on their own EV-fleet, Smart Charging services in both V1G and V2G modes. A smart charging platform is able to monitor, forecast, optimize, and control the charging behaviour of the EV fleet.

Flexible electricity grid networks

In urban areas, under current market and regulatory conditions, achievable operational savings or revenues, are not enough to ensure a return on such a system’s investment. What EDF and the other involved project partners are targeting, is to test the possibility to operate these generation and storage means to deliver grid services.

An open and standardised data platform

At the heart of the Métropole demonstrators is the City Innovation Platform (CIP), for sorting, storing and managing a large volume of data. in a standard format and coming from a wide variety of data sources and formats. By bringing all the data into a common format, this approach makes it possible to implement open and interoperable solutions. For this, the CIP relies on the Fiware foundation guidelines, the Orion Context broker.

Collective self-consumption at building scale

Why implement?

The main objective of this use case is to assess the benefits and analyse the barriers (legal, financial, technical) that prevent the development of the collective self-consumption market at building scale. One sub-objective will be to experiment different technologies to increase the ratio of PV self-consumption such as lithium-ion batteries.

Optimization of social housing heating

Why implement?

The aim of this measure is to integrate a smart control system within the district heating distribution, giving the possibility to adjust heat supply to the individual demand in each apartment according to their sun/wind exposures but also considering accurate indoor temperature. Work involved the hydraulic separation of networks, the installation of sensor in tenants’ flat, and for solar and wind, and control valves.

Particular attention was paid to the tenants by informing them: flyers were distributed before the work in their letterboxes and posters were put on all the floors with indication of the reasons for the work, the inconvenience caused. Besides, a telephone number was made available.

After two years of experimentation, the first results show a decrease in energy consumption of 8% to 15% depending on the solutions, to be confirmed during the next heating season.
It is also worth noting an improvement in the comfort of the inhabitants especially for those located in the North where the results are most promising.

Smart charging of a city owned EV-fleet

Why implement?

Smart Charging is seen as part of the solution for sustainable and durable growth of such infrastructure, by lowering the charging’s grid-impacts: by controlling the power withdraw for each charging point, EV-battery loading can be adapted to the end-user’s mobility needs (foreseen time and range) and electricity tariffs, lowering it for minimizing both grid impacts and expenditures. Moreover, by deploying V2G compatible technology, the EV batteries can also be used to inject energy to the grid and by providing energy services, participate in the stability of the electricity grid.

Why to use in my city? (USPs)

Smart Charging (V1G or V2G) is recognised by the scientific and industrial community as one of the most powerful ways to reduce and postpone the costly grid reinforcements needed to host the growing e-mobility needs.
Smart Charging can not only reduce the overall electricity costs associated with EV charging, but, can also provide new additional revenues flow by operating a EV-fleet to provide grid services to the electricity markets via an Aggregator, thanks to the V2G technology.
Smart charging ensures to lower the impact of E-mobility on a city’s or regions infrastructure while ameliorating at the same time the overall environmental and economic impact of the mobility sector, contributing to better integrate vRES by contributing to stabilizing the electric grid and further lowering direct CO2 emissions.

Flexible electricity grid networks

Why implement?

Once these assets are equipped with a reliable EMS capable of communicating with an Aggregator, they can interact with the electricity market and so participate to secure electricity supply quality and security. Overall, the system becomes more resilient, making the best use of local RES and indeed, by offsetting fuel-based power plants for providing energy services.

Through this Local EMS, IRIS buildings become active players in the energy market and, once bundled with other generation and storage means, they might provide additional revenues for stakeholders.

Why to use in my city? (USPs)

Thanks to the deployed Local EMS, renewable electricity is used at local scale in priority and thanks to the integrated “intelligence” (forecast and optimization), the overall exploitation performances are maximised.
Interfacing an Aggregator with the local EMS, can enable new revenue streams and put the locally produced energy at the service of the grid, enabling the wider society to leverage from it by providing vital services based on RES energy to the grid.
It further contributes to CO2 emission reduction

An open and standardised data platform

Why implement?

The Nice Côte d´Azur Metropolis is committed to a smart city strategy aimed at optimising the functioning of the local authority’s internal services and offering more efficient urban services for its citizens or partners.

The objective is to improve the efficiency of public services and optimise resources thanks to digital technology, with a desire to replicate in the municipalities of the region.

Why to use in my city? (USPs)

This strategy is accompanied by a regional fleet of sensors that collects data from several sources and of different kinds, in order to supply a data warehouse – IRIS City Innovaton Platform – based on Fiware technology.
Data from sensors or cameras are collected and transmitted in a secure manner. They are centralised and standardised, thus allowing transversal use. These data are then qualified in order to create a space of trust around the data. They can then be valued by the development of services for the efficiency of the community.
