Anglian Water and Connected Energy worked together on a project to understand how to maximise the potential of renewable energy projects and offer grid services support by integrating E-STOR energy storage systems on sites. Anglian Water's aim was to make the most of storing energy generated from their renewable sources, like the solar panels they plan to install across the region.  Integrating batteries into these projects would ensure more of the renewable power is used onsite. The installed system also took advantage of any time of day energy costs differences and assessed the potential for the system to supply energy grid services at further Anglian Water sites.

3. The Energy Challenge
• Average industrial energy prices, including
the Climate Change Levy, increased in real
terms by 4.0 per cent between Q2 2016 and
Q2 2017 (gov.uk).
• Up to 55% of your electricity bill is
related to non-energy cost. By 2020 we
expect these costs to account in excess of
60% of your energy bill.
• Energy prices are increasing and your
business cannot be put on hold during
periods of high energy costs.

An E-STOR has
been in
operation for 3
years
Systems are in
operation in
the UK,
Belgium,
Germany and the
Neterlands

7. Operating an E-STOR
Configure to specific site conditions
and provide optimised control of the
E-STOR to improve energy use.
Directly integrate to an aggregator
or Virtual Power Plant to create new
revenue streams by providing rapid
response to grid conditions.
Track or directly integrate with a
metered source to provide real time
grid load/constraint management.
Provide resilient back up supply.

11. Revenue Share
Agreement
• A Revenue sharing agreement allows the client to benefit
from any upside generated by the battery without any risk
of downside.
• Whatever the revenue streams are (either via savings or
grid services), however they are generated, the client
will receive a share of them.
• This structure will mitigate regulation and market risk
as the battery will always try to maximise profit by
moving across the various revenues available to a BtM
storage asset. The flexibility of this technology is what
gives investors great comfort when considering future
cash flow.
• The investor, the client and the aggregator are all
aligned with an RSA – All parties want to optimise the
battery operation to produce the largest revenues,
however they are generated. ARGONAUT POWER LIMITED

• The Customer saved £ 100
on their energy bill
• After calculating the RSA
we can see that the
Customers share of
revenue is £ 25
• Therefore the Customer
needs to pay the SPV £ 75
