„Carrega‘t d‘Energia“
March 2015: Campaign “Carrega’t d’Energia”
Goals:
(1) GENERATION: To show the energy
resources available on building
rooftops.
(2) EFFICIENCY: To provide information
about how much electricity is
consumed at home and how to
reduce this consumption.

1. Renewable Energy Generation – Maps of resources
Services offered
• Solar Thermal
• Solar PV
• Mini Wind Turbine

2. Energy Savings – Virtual Energy Advisor
Services offered
The Virtual Energy Advisor is a
free online platform that:
• Shows electricity consumption
and consumption profiles.
• Gives tips and advices about
how to reduce the electricity
consumption.
• Provides the opportunity of
becoming part of a virtual
community to exchange
opinions, advices and best
practices.
• Compares current consumption
with consumption of previous
years.
• Compares user consumption with
other users with similar
characteristics to promote energy
efficient behaviour.

Options for data collection
Electricity consumption data is read by the platform at
different levels depending on user’s choice:
1. Basic level: monthly or bimonthly electricity
consumption data (electricity bills).
2. Advanced level: real time electricity consumption
data (via Smart meter monitoring).
As a result of the campaign, about 400 citizens will
have received a free Smart meter installed at home.

Smart meters
Requests for users:
 Domestic electricity tariff
 Wifi acess
Estimated cost of the device:
 150-160€ incl. installation cost
Technical data:
• Single phase meter.
• Placed at the entrance
of the distribution
board.
• Reads current and
voltage.
• Wi-fi: Creates a
network and send the
information via the
home router.
• Stores data when the
router is disconnected.

Energy Saving Tips
Wash your clothes at low
temperature:
Investment 0 €
Difficulty Low
Total money savings About 538€
Use the coldest temperature possible
in your washing machine as most of
the energy consumption is due to
water heating (up to 90%).
Savings are calculated for a 10-years
lifetime of the washing machine.

Results
Number of users of Virtual Energy Advisor and Smart meters:
 639 users have shown interest in registering.
 Up to now, 362 users send data from their meters to the
platform or are in process of doing so.
Technical considerations:
The management of this number of users generates:
 50 to 70 emails a week about registration and management issues.
 2 days a week are necessary for a technician to make the management and
processing of data.
 467 users have been correctly registered.
 428 users showed interest in getting a smart meter.
 Estimation: In total, 415 users will be able to install the free smart meter.
