About Endesa

Renewable and efficient light generation. The zone has around 11MW of renewable generation capacity, which includes numerous roof-mounted photovoltaic installations spread throughout the city, a cogeneration facility, vertical-axis wind turbines and generation systems integrated in street lighting. All these generation systems, combined with two battery-based storage facilities, are used to manage consumption more efficiently. Nearly 100 street lights have been replaced with new lights featuring energy-efficient technologies (including LED and halogen lighting), which are managed via a point-to-point control system.

A small network of recharging points has also been installed for the trialling of V2G (Vehicle to Grid) technology.

It is hoped that Smartcity will help the city to comply with European guidelines for the energy sector, which promote efficiency, the use of renewable energies and advanced grids with storage capacity. The main objectives of the project are:

• Automated meter readings. Endesa will install its new smart meters, allowing for more accurate billing and an end to estimates, thus resulting in more transparent bills. Readings will be carried out in real-time and customers will be offered an improved service, they will be able to manage consumption better and consult their bills online; grid disconnections will be reported immediately and breakdowns managed more efficiently.
• Consumers will change their habits as they can consult their consumption, rates and the environmental impact online.
• Customer awareness will be raised.
• Promotion of the electric vehicle; consumption management, batteries and loads will be managed correctly to ensure optimal use of the power grid.
• PLC communications between transformer centres.
• Energy efficiency in public and private buildings. Possible energy management in hospitals.
• Efficient management of public lighting which is important so that city councils can reduce consumption. Installation of noise sensors, environmental pollution sensors, surveillance cameras, communications services, presence sensors etc…
• Battery management and the installation of storage capacity in generators.
• Automated manoeuvres to install remotely controlled meters on the MV and LV network. The disconnection time during breakdowns will be reduced as will the number of customer complaints. Grid usage will be optimised.
• Alternative power producers will be installed, managed and controlled (photovoltaic, micro wind, trigeneration, biogas, hydrogen cells, CHP….)
• It will be possible to draw up consumption patterns to help improve planning and the use of alternative energies.
• The smart grid will help manage excess output of certain producers.
• Important objective: cut CO2 emissions.
• Changing the load curve by lowering consumption peaks and flattening the demand curve.
• This will help the company meet European guidelines for the energy sector which promote efficiency, the use of renewable energies and advanced grids with storage capacity.
