ENERGY OPTIMISATION SOLUTIONS

Save up to 10% of your power bill with no associated cost

Energy Optimisation - The ProblemThe problem

Power accounts for between 40-60% of data centre OPEX and is set to rise as power costs inevitably increase. Corporate carbon footprint is becoming more critical.

The grid is reaching capacity in some regions and requires more balancing as more renewable generation is connected.

 


The concept

Install a multi megawatt Battery Energy Storage System (BESS) that provides power when electricity costs are highest and re-charges the BESS when electricity is lower cost automatically. Each one hour autonomy 1 megawatt battery fits in one ISO 40ft container.
The battery and installation are provided free of charge once the contact is agreed and signed so the data centre operator has no costs, either capital or operational.

 

The benefits

  • Electricity bills reduce by circa 10% to the operator
  • Potentially an additional level of power redundancy if grid power fluctuates or fails
  • Competitive advantage for co-location operators if tenants receive the savings and greater comfort levels for tenants because of the additional back up from the BESS
  • Good PR as carbon footprint benefit as more renewable energy can be connected to the grid and it helps stabilise the grid

 

Frequently asked questions

It sounds ‘too good to be true’ what are my obligations?
You have to sign an Energy Performance contract, usually 10 years, find external space for 40 ft (12.2m) ISO container, one per MW and have minimum continuous demand of 1MW, although in some cases from 500kW upwards (or £500,000 electricity bill PA).

Energy Optimisation - FAQsAre there any maintenance costs?
No, all maintenance costs are paid by EOS and any failures are covered by the comprehensive warranties.

How does it integrate into my Mains panel?
An adequately sized mains breaker has to be installed and cabled to the external container

Do the containers have to be outside?
Yes for the air conditioning condensers but these might be installed remotely if there is only internal space

Is there a risk?
The containers have independent fire detection and extinguishing installed which can be linked to the ‘house system’. The battery feeds the panel via a breaker, which trips, isolating the battery completely under fault or fire conditions, so there is no risk to the existing infrastructure.

What do you require to provide a proposal?
12 months of billing invoices and half hour meter readings which we can obtain from your supplier if you sign an authorisation letter

How long does the installation take from signing of contract?
It takes about 6 months to hand over of the solution and it goes on line

How does the control system work?
The systems are complete with sophisticated software that controls the charging and discharging of the system in accordance with the electricity network charging regime and grid frequency

How do EOS get paid?
We share in the savings the system achieves as benchmarked against a ‘business as usual’ measurement and verification every month
