QUITE SIMPLY - Use and store solar energy during the day - And it’s free
Draw down stored energy from the battery. If you need more power then consume power direct from the grid as required. You can also use the grid to charge the battery when your tariff is at it cheapest (and when the sun doesn’t shine) and save £££

FIRST ECN logistics / industrial building
at The Hub Birmingham
hub 69 THE new, high quality specULATIVE ECN BUILDING - 68,895 sq ft (6,401 sq m) AVAILABLE 0CT 2017
The first EPC A+ B2/B8 Building in the West Midlands
The first EPC A+ non domestic-building in Birmingham*
IT ADDS UP
HAVE A LOOK AT THE NUMBERS BELOW - WE’VE NOT HIDDEN IT IN ANY SMALL PRINT - AN ECN BUILDING REALLY DOES ADD UP TO Electricity COST NEUTRAL
ECN GOT YOUR BACK UP?
STAY CALM DURING A POWER CUT AS THE ECN BUILDING CAN ALSO USE THE STORED POWER ON DEMAND - SO THERE ISN’T AN INTERUPTION TO YOUR BUSINESS. PHEW.
The following terms and conditions detail the assumptions made in the ECN model:
IM Properties will provide within Hub 69 a 250kW solar array with a forecast generation of 224,286 kWhr alongside a 100kW/170kWh Tesla battery. The building will have a 300 KVA import capacity supply. The calculation is based upon 10% roof lights and PVs and assumes an unheated warehouse lit with LED lighting.
The warehouse will be racked with wide aisle racking. The calculations are based upon a typical B8 storage use. The model is based upon the following hours of operation: 16 hours a day 6 days a week in the warehouse (i.e. 6 am – 10 pm) and 10 hours a day 5 days a week in the office (i.e. 8 am – 6 pm).
The calculations are based upon a supply contract from Npower wherein which the daytime rate is 10.623p and the night-time rate is 14.804p per kwh. From this the following electricity consumption estimate has been calculated: office consumption is 123,138 KWH, warehouse small power consumption is 132,787 KWH and warehouse lighting consumption is 48,000 kwh. This provides an electricity cost calculation as follows: total annual consumption = 303,925 kwh. Cost per annum at 10.623p = £32,286 plus £4,933 standing and capacity charge on 300 KVA = £37,218. Self-consumption of generated energy is estimated at 90% which is 201,857 kwh of ‘free’ energy.
The remaining balance of £15,775 per annum is reduced by revenue from FFR (Firm Frequency Response) amounting to £11,669 which is an ancillary service (subsidised by National Grid) received via an aggregator. The remaining revenues are received through TNUoS (Transmission Use of System charges, often known as TRIAD) (£7,124) and DUoS (Distributed Use of System charges) which is a direct saving on the electricity bill (£1,256). To achieve the savings on the electricity bill a standard supply contract (also known as a standard pass through contract) with these items listed a separate line items is required. There is no additional charges or levy’s from any supplier for this.
The results demonstrate an electricity cost neutral model with a potential additional nett revenue of £4,273 to the tenant. Currently there is no provision to export the surplus 10% of generated energy to the grid although this may be possible which would generate further revenue.
*Hub 69 is the first EPC A+ B2/B8 Building in the West Midlands and the first EPC A+ non domestic-building in Birmingham
