When you require an electricity supply for a new development, you need to ask the organisation who owns the cables in your areas whether there is available capacity. This is your Distribution Network Operator (DNO), who will also own or ‘adopt’ any new cables or infrastructure installed to give you a supply.
However, the DNO isn’t the only option: Independent Distribution Network Operators (IDNOs) can own the new network too. Here, you will find all you need to know about each.
What is a Distribution Network Operator (DNO)?
The electricity distribution network carries electricity between the transmission grid (operated by National Grid) and the businesses and householders who are the end users. There are 14 Distribution Network Operators (DNOs) across England, Scotland and Wales, and they are each responsible for a specific geographical area.
The DNOs are licenced by Ofgem to distribute electricity. They own, operate and maintain the electricity infrastructure (such as primary and distri...
Following the sale of a partially constructed site, the new developer requested help with the electrical connection.
The care home required a 200KVA bulk supply which would terminate in a Heavy Duty Cut Out within the building.
A High Voltage (HV) point of connection was granted by Western Power Distribution (WPD) on the opposite side of the road. The substation was located to minimise the HV cable run and to avoid crossing the site entrance.
The Rock Team installed a 315kVA substation in a GRP at the site boundary so there would be easy access for WPD and the adopting IDNO.
A bulk supply was installed in the client’s meter room.
Whilst the offsite cable route was a short stretch across the road, care was taken to minimise disruption to the local properties with driveways in the proximity of the excavations.
Darren Huxley, Project Manager commented: "It is great when we can offer small substations on developments that require lower loads and get it adop...
Widespread availability of Electric Vehicle (EV) charging is critical in facilitating the transition to ultra-low emission vehicles and securing the Government’s net zero carbon targets.
A pivotal driver in the increase of EV charging is the proposed changes to Building Regulations which will require chargepoints to be included in new residential and commercial developments, as well as some existing commercial properties.
The Government is yet to publish its final ruling (it was anticipated in January 2020), but the proposals are:
For new build residential developments, either housing or apartments, a chargepoint should be installed for each dwelling with a dedicated parking space.
For conversions of commercial properties to residential, a chargepoint will be required for each dwelling with a dedicated parking space as long as the building works impact the car park or the electrical infrastructure.
For residential buildings that have more than 10 p...
There are an increasing number of commercial buildings being repurposed into apartment developments. Very often, our clients have an existing bulk supply into the building, but want to split it into individual meters for each new premise – be it a retail unit or apartment.
If you are looking for a way to provide multiple individually-metered supplies, but also avoid submetering, this article discusses your options.
WHAT ARE THE OPTIONS FOR GETTING AN ELECTRICAL CONNECTION?
If your building has an existing supply and it is of sufficient capacity, your instant thought may be to retain this bulk-metered supply, and then use sub-meters for each apartment or commercial supply. Not only would be the responsibility of the landlord or building owner to meter and bill each premise, it would also be their responsibility to maintain and retain the network in the case of a fault. This is often termed a Building Network Operator (or BNO) installation because the responsibility reverts to the buil...
A 50KW Electric Vehicle (EV) charger installed at The Brychan pub required a new connection from the local Low Voltage (LV) network.
Based on a large leisure park, the parking bays were adjacent to a Travelodge and the Rock Team needed to minimise disturbance to the hotel.
The Point of Connection provided by Western Power Distribution was in a congested footpath.
The Rock Team completed all the civil electrical works from the final closing joint to the installation of EV chargers.
To expedite the installation, the EV charger was installed first and the electrical connection works undertaken later to fit with the WPD’s availability. WPD attended for the final closing joint to facilitate the identification of the correct cable in the congested area.
Rock Power programmed the work to suit the off-site peak times for the Travelodge and to ensure no inconvenience for the local businesses and customers.
Dan Wooding, Project Manager commented: “Another great EV cha...
By 2035 the UK Government plans to ban new petrol and diesel car sales. Couple this with the dramatic year-on-year percentage growth in pure Electric Vehicles (EVs)s and it is clear to see an impending shift to electric.
Streets will be quieter and the air cleaner. There will be a much bigger shift in our driving habits which accompanies this: primarily, how we fuel. As the EV manufacturers and charging point networks help us overcome our ‘range anxiety’, we’ll be swapping out our petrol station pit stops for regular charges. Will it become second nature for us to just ‘plug in’ every time we ‘pull up’?
How will this impact the network?
If we all plug in at the same time, there will be higher peak loads in the electricity system which provides a challenge for the Distribution Network Operators who manage it. Surprisingly, the impact on the distribution network is anticipated to be minimal in the shorter 5 and 10 year projections. It is only in 20...
Over the past year, Rock Power Connections have been involved in an increasing number of electrical connections for Electric Vehicle [EV] charger projects. These projects have covered each of the different Distribution Network Operator [DNO] regions and have ranged from fairly small supplies for a single rapid charger through to more considerable supplies for banks of rapid chargers.
As an Independent Connections Provider, we are very experienced in working with the DNOs to identify where we may connect to their network to obtain an electrical supply for a site. When the load is for Electric Vehicle (EV) chargers, we have found the process to be more inconsistent and more challenging.
Our findings are:
#1.THE APPLICATION PROCEDURE STARTS POSITIVELY. Each of the DNOs’ new connections teams proactively make contact and talk us through how easy it should be. This is akin to applications for non-EV charger sites.
A development of twin hotels known as The Gantry in Stratford, London required two looped substations from a High Voltage (HV) point of connection on a busy road.
The Gantry includes a 285 bedroom hotel over 18-storeys by the Hilton Curio Collection and a 136 room longstay aparthotel over 17-storeys by Adagio.
As the development also includes new bars and restaurants on the lower floors and a new sky-bar on the 18th floor, the overall load was 2MVA.
The Point of Connection was granted by UKPN and involved a road crossing and considerable run to site along a block-paved walkway. Alongside it being a very busy construction site, the DLR station and Westfield shopping centre are in close proximity.
The installation comprised a 1MVA substation and 1.5MVA substation, each providing a LV bulk-metered supply in an adjacent switchroom.
Both substations were midel-filled due to their location and internal rooms.
Due to the number of contractors onsite, the work wa...
