MEO Energy is an ICT solution developed by PT that allows customers to monitor and reduce their home energy consumption and carbon footprint. The solution involves installing a device on the home's electric board to monitor usage, which connects wirelessly to a data collection device and TV display. The service provides information on energy usage, costs, price plans and tips to save energy. It aims to help customers save 20-40% on energy usage and costs while also reducing their environmental impact. A family's testimony shows how using MEO Energy helped them optimize appliance use and lower their monthly consumption by 36%.

display of domestic electric consumption on TV – Interactive MEO – providing information's on:
Energy consumption in a choice of time periods;
Cost forecast, depending on previous consumptions;
What is the best price plan, taking into consideration the domestic electric consumption profile.
With MEO Energy the client can adopt the best domestic energy saving practices:
Saving on consumptions and waste reduction;
Acknowledging and controlling electric consumptions, without comfort prejudice;
Choosing the electric power and price plan most suitable for the client;
Following the advice and recommendation on energy savings.
MEO Energy is an innovative
domestic carbon footprint and
budget management solution!

4. 3. MEO Energy – Solution characteristics

5. 4.MEO Energy – Service advantadges
MEO Energy has 4 categories of information (vertical navigation):
Consumption
Price Plans
Recommendations
Settings
Allows the client to understand how the various equipments and lightening are consuming
energy;
This way, it becomes easier to change consumption behaviour, increasing domestic budget
and carbon footprint savings.
MEO Energy displays graphics of electric
consumption in 4 time periods:
Daily – hourly;
Weakly – from Monday to Sunday;
Monthly – daily;
Annually – monthly.
For each time period, it is possible to see:
The consumption in Euros;
The consumption in kWh;
The matching carbon footprint.

6. 5.MEO Energy – Managing the Carbon Footprint
With this service, the client can visualize:
The Carbon Dioxide emissions (in CO₂
kg), associated to the electric energy
consumption;
The number of trees needed to nullify
the CO₂ emissions effect;
A colour bar, placing the domestic
consumption made.
MEO Energy, allows the client to assess the environmental impact of the consumptions made
and:
Build a better environmental awareness and more responsible consumption behaviour;

promote families’ responsible consumption.

7. 6.MEO Energy – Managing the domestic budget
The client has access to a comparative chart that
displays for the different time periods (day, week,
month and year):
1- Current consumption values;
2- Values for the previously assessed consumptions;
3- Linear forecast for the consumption expected until the
end of each time period.
The Price Plan tool allows the client to simulate a
monthly cost forecast for each one of the
electricity supplier price plans, choosing this way
the most suitable tariff.
MEO Energy, allows the client to assess the current consumption deviation comparing with
the usual consumptions, evaluating costs for each time period. As a result, the client can:
• Manage domestic budget based on consumptions knowledge;
• Boost a better domestic sustainability.
With this service, PT reinforces its social and environmental sustainability, promoting client’s
responsible domestic consumption.

Main household appliances:
Oven, ceramic hob, microwaves, coffee maker, fridge, 2 TVs with MEO Service, electric
heating, washing machine / tumble dryer, dishwasher, 2 laptops, DVD player.
Using MEO Energy
This service helped the family to optimize consumption behaviour. Gradually, they started to:
Make a better use of the washing machine, tumble dryer and dishwasher, using these only
when full and in shorter and lower temperature programmes;
Set the fridge to suitable temperature and avoid placing hot food inside;
Defrost food at room temperature, avoiding microwave use and for this…
Cook larger amounts of food at the same time, to be consumed in more than one day, for
example soup, being reheated later;
Make a better use of the oven;
Use the microwaves to warm the baby’s milk instead of the kettle or the ceramic hob;
During summertime open windows more often to make the air flow, avoiding an abusive
use of the air-conditioning system;
Turn of the lights every time a room is empty;
Only warm room divisions when people are there and it is actually needed;
Unplug all appliances with stand by that are not being used recurrently;
Change the illumination to energy saving light bulbs and maximize solar lightning use.

10. 10.MEO Energy – Outcomes
In the months previous to MEO Energy installation, the
average consumption was 210 kWh/month. Currently the
family only consumes 135 kWh/month (-36%).
With Meo Energy, and for an
average consumption behaviour,
we estimate 20% to 40% energy
and carbon footprint savings.
