Varberg Energi pilots 85 MW city-wide virtual power plant Nätflex in Varberg, Sweden; income to energy customers providing flexibility services

COPPER Case Study - Antwerp

Case Study
How DSO Varberg Energi is
piloting a city-wide virtual
power plant that citizens
can join through an app
With funding from the European
Union
through
the
COPPER
initiative, the Distribution System
Operator (DSO) Varberg Energi
will pilot an 85 MW virtual power
plant called Nätflex, capable of
balancing renewable loads for a
town of 35,000 while providing
an income to energy customers
who provide flexibility services

CHALLENGE
As a Distribution System Operator (DSO),
Varberg Energi is responsible for ensuring
that the local grid can deliver reliable
power
supply
to
all
homes
and
businesses. Flexibility is key to this
service, and by 2026, Varberg Energi will
have plugged in 85MW of flexible
charging stations, batteries at grid level
and in homes, as well flexible power
providers producers include wind farms
and solar power plants.
But to make it possible and
convenient for private customers,
Varberg Energie need a system to
make it easy and attractive for
their energy customers to offer
their solar panels and household
batteries to provide flexibility
services.

Working with greentech provider FerroAmp,
Varberg Energi will pilot a virtual power plant
that will make it easy for private energy
customers to connect their assets up to the
local grid and earn an income from providing
flexibility services, being paid to store and
dispatch energy when needed.
The Nätflex system, which allows energy
customers
using
Ferroamp's
balancing
software Energy Hub to control how their
assets interact with the virtual power plant
through an app. This will allow customers to
contribute to a healthy local grid and earn an
income with just a few taps on their phone.

OBJECTIVES
Through COPPER, Varberg Energi will expand its virtual
power plant to private customers through Nätflex,
connecting generating assets from batteries to wind
turbines into a intelligently-controlled power plant.
As a publically-owned DSO, Varberg Energi will
work closely with the municipality to ensure the
power plant works towards the city’s strategic
energy objectives.
Nätflex will allow private energy customers to provide
flexibility services to the grid and earn an income in
the process, keeping the local grid healthy and
democratising the rewards for flexibility.
Prepare a virtual power plant at
city-wide scale
Develop a new way of working
between DSOs and cities
Enable citizen participation in
flexibility incentives

With a lot of flexible resources, we want to be able to stable
the electricity system and increase the amount of
renewable electricity production in the existing system.
