Battery Storage Q&A's

What is a battery storage facility?
We need Circa. 10,000 sq. ft. (929 sq. m) industrial building, or containers, housing batteries capable of supplying, 10MW of power to the National Grid.
Battery storage uses industrial scale battery technology to provide power to the National Grid at times of peak demand, The Batteries are charged when there is a surplus of energy being generated, and then discharged quickly to meet sudden increases in demand. The technology has existed for many years, but has only recently been developed and manufactured on a scale that makes this type of application commercially viable.

What is a suitable site?
Land: › Minimum 0.25 acres (0.1 Ha) suitable for construction of a 10,000-sq. ft. (929 sq. m) industrial building OR land for a container based facility, comprising 11 shipping containers, If a building is required, this will be constructed by A Circuit Ltd, at their cost, to an agreed specification.
Proximity to electrical connection (33kV) or next to a substation, with existing planning consent for industrial or storage uses, or good potential to secure planning consent on existing buildings will of course carry a good premium.
Existing industrial buildings of 9,000–11,000 sq. ft. (836–1,021 sq m) Minimum height to eaves of 5m Detached or terraced In good condition, with remaining design life of 25 yrs.+, Proximity to populated areas increases potential for cost effective, high speed connection to National Grid.

What’s in it for you as the Landlord?
Single option premium of up to £10,000* with Starting rents of up to £50,000* per annum these are Annual RPI linked rent reviews for duration of term which is based on 25 year, subject to tenant only break at 15 years this gives a great and secure income stream suitable for onward investment sale.
Where a building is constructed, the Landlord has option to purchase the building for £1 at the end of the lease term *assumes 10,000 sq. ft. building or containerised solution on best available terms, the value of sites/buildings is a function of the cost of connecting to the National Grid, and the speed at which power can be discharged in to the network.
Further details are provided in the Landlords information pack, available on request. Sites will be dealt with on an ‘open book’ basis, with the cost and speed of connection available shared with Landlords on receipt of an offer from the Distribution Network Operator (DNO). Landlords will not be obligated to proceed until a grid offer has been received and rental level and option premium has been confirmed.

Who are A Circuit Ltd?
A Circuit Ltd is a UK based leading developer and operator of low carbon electricity generation and storage projects. A Circuit Ltd have worked successfully with commercial and large industrial clients on renewable energy projects.
We are also an ICP (Independent Connections Provider) this gives us access to all the advantages of working closely with Lloyds of London, so there can be no better support system anywhere in the World.

Is planning permission required?
In most cases, there will be a requirement to secure planning consent for the proposed energy generation use. However, because the process will take place within a building that appears to be a standard industrial unit or form a containerised solution, securing a planning consent is not expected to be contentious and may in some cases be a simple change of use application.
Is this linked to Feed-in-Tariffs or other Government incentives? Income to projects is derived directly from the electricity markets. There is no direct linkage to government devised tax payer funded incentive schemes. The regulatory environment is therefore much more stable than has historically been the case with Government incentive schemes such as the Feed-in-Tariff.

What will the cost to Landlords be?
A Circuit Ltd financial backer’s cover all costs in connection, with progressing the Battery Storage facility, including a contribution toward Landlord’s professional costs.

Do I need to be concerned about Lithium Ion batteries?
A Circuit Ltd will employ fully tested and warranted technologies from established and trusted providers. In addition, A Circuit Ltd will comprehensively insure all installations.

Please tell me how Lithium Ion Batteries Work?
Like any other battery, a rechargeable lithium-ion battery is made of one or more power-generating compartments called cells. Each cell has essentially three components:
A positive electrode (connected to the battery’s positive or + terminal), a negative electrode (connected to the negative or − terminal), and a chemical called an electrolyte in between them. The positive electrode is typically made from a chemical compound called lithium-cobalt oxide (LiCoO2) or, in newer batteries, from lithium iron phosphate (LiFePO4). The negative electrode is generally made from carbon (graphite) and the electrolyte varies from one type of battery to another—but isn’t too important in understanding the basic idea of how the battery works.
All lithium-ion batteries work in broadly the same way. When the battery is charging up, the lithium-cobalt oxide, positive electrode gives up some of its lithium ions, which move through the electrolyte to the negative, graphite electrode and remain there. The battery takes in and stores energy during this process. When the battery is discharging, the lithium ions move back across the electrolyte to the positive electrode, producing the energy that powers the battery. In both cases, electrons flow in the opposite direction to the ions around the outer circuit. Electrons do not flow through the electrolyte: it’s effectively an insulating barrier, so far as electrons are concerned.
The movement of ions (through the electrolyte) and electrons (around the external circuit, in the opposite direction) are interconnected processes, and if either stops so does the other. If ions stop moving through the electrolyte because the battery completely discharges, electrons can’t move through the outer circuit either—so you lose your power. Similarly, if you switch off whatever the battery is powering, the flow of electrons stops and so does the flow of ions. The battery essentially stops discharging at a high rate (but it does keep on discharging, at a very slow rate, even with the appliance disconnected).
Unlike simpler batteries, lithium-ion ones have built in electronic controllers that regulate how they charge and discharge.
