Cheaper and greener electricity at home

Cheaper and greener electricity at home


Our days are regulated by
the use of appliances that weigh on our electricity bills.
But machines like air conditioning, water boilers
or refrigerators could be less expensive if used in a clever way. To help us save
money, experts from the EU-funded project ADDRESS have developed
this Energy Box, currently tested by Spanish households. The Energy Box is connected to the Internet. I can connect to
the system using my computer. I can view the loads and schedule them. In the case of the dishwasher, there are less expensive times to use it I indicate that I would like to use it
during that time period, and the system depending
on the current loads for electricity, turn the machine on. The consumer becomes active, and can benefit from lower costs
while using the same amount of electricity. I receive a message that
I should use less tan 1kW/h if I do it I
will get 0.1 euros back. That may not sound like a lot
but in the long-term, it could mean a lower
electricity bill. The box is actually connected
to the grid via an aggregator that sends and receives
information about the consumer’s preferences and the
electricity loads available. By aggregating many consumers,
the system allows the better management of energy flows. When we have a high generation of Distributed Energy
Sources, mainly renewables we can use active demand
to increase the consumption of the consumers. It’s
a move of the consumption from the future to now.
The main advantage is that you can connect more renewables. Thanks to the aggregator’s function, the ADDRESS model
offers a win-win situation both for the distributor
and the consumer’s wallet. It also takes a step further
towards smarter grids, in which green energies will
be fully exploited. The European goal of a carbon-free
economy by 2050 is right on track to become a reality.
