Second Life Battery Storage technology at Clepington Road

04 April, 2023 | Dundee Electric

Dundee City Council is working with Connected Energy to include second life battery storage technology at our new Clepington Road hub, helping to capture the energy generated by the hub’s solar array and ease pressure on the grid.

Having upgraded our fourth charging hub with a state-of-the-art water filtration system, we are now advancing our collaboration with Connected Energy, by adding second life battery storage on both the public and private fleet sides of the Clepington Road charging hub.

Connected Energy is an award-winning supplier of second life battery energy storage systems (BESS). One of the company’s first commercial systems was installed at Dundee’s Princess Street depot to store electricity from the solar PV on site which is used to support the electricity demands caused by EV charging.

Offering power flexibility and new systems

Two new second life battery storage systems will help Dundee reach its 2023 goals by offering a greener energy alternative while powering its circular economy. Implementing a battery energy storage system allows Dundee Council to store electricity through its own supply or from their solar PW array, supporting Dundee city’s own decarbonisation agenda.

The new E-STOR systems supplied by Connected Energy offer easier access to upgrading EV-Charging hubs grid capacity through its modular and scalable design. As the demand for electric vehicles is continuously growing, its wide range of configurations allow Dundee Council to add more charges to its grid capacity, without overloading the grid.

Reusable EV-batteries are a central part of the E-STOR system by allowing the battery to charge and discharge depending on the predetermined criteria; charging through solar canopies when the sun is shining, and discharging when the grid energy is most expensive or when charging hubs are high in demand.

How will reused EV batteries support Dundee’s 2023 and 2030 goals?

The battery units house batteries from old 24 Renault Kangoo EV batteries that can no longer reach full charge, however they are still able to use 75-80% of their original capacity. By giving EV batteries a second life, Dundee is;

Helping decarbonise the grid by reducing embedded CO2 in EVs through storing and using renewable energy
Lowering the energy costs during peak shaving and periods of high demand
Increasing the supply of batteries available for stationary energy storage and thereby reducing the costs by 30% to 70%
Accelerating the uptake of EVs as Battery electric vehicles are widely regarded as crucial to decarbonising the transport sector and achieving the Paris Agreement Goals

Testimonials

“I love my new Nissan Leaf… the forward-thinking city council are at the forefront of the whole electric car revolution”

Lorraine Kelly

“Electric taxis always surprise our customers with how quiet they are. The switch from fuel to electricity has saved us thousands – and it’s clean too!”

There are now a total of 187 electric taxis operating in Dundee which is 25% of all taxis operating in the city.

Dundee Taxis

“Electric vehicles have reduced the city’s cO2 levels by 987 tonnes so far (Sept 2017)”

Dundee City Council have 223 electric vehicles (and counting) in their fleet, the biggest of any UK local authority.

Gary McRae, Dundee City Council

“The excellent charging infrastructure in Dundee makes running an electric car very easy. I often plug in to one of the chargers in town, pop to the shops and my Nissan Leaf is fully charged by the time I’m done. I can’t wait to use the charging hubs that are planned across the city. The ability to park for free in the Dundee City Council car parks because my car has zero emissions is an added bonus.”

Elinor, Dundee

“We are now using an electric car since 2012 and will not go back to a petrol car. The drive is smooth, responsive and quiet. With Dundee getting better and better with chargers in several places, free parking in Council car parks, what’s not to like? The car has saved us money compared to the Ford Ka we had before, with currently over 90,000 miles, you can’t tell us it’s not used. Looking forward to the new charging hubs in Dundee.”

Erwin, Alyth

“EVs are over 60% cheaper to refuel than modern petrol and diesel cars and have only 1% of the moving components, so they’re really reliable. There are EVs that have clocked up over 174,000 miles in three years and only needed a ball bearing replaced. Switching to an EV from a 70mpg hybrid and charging it at home has saved me £500 per year on fuel and maintenance alone – double that if I only use Dundee’s free public charge points!”

Euan, Dundee University graduate

“Our two electric vans have completely transformed our business. Not only have they helped reduced our running costs, but they are much better for the environment and work well with the stop start style of driving that we do on our free pick-up and delivery service. The move over to electric vehicles has been extremely easy due to the excellent facilities for charging in the local Dundee area. We are even considering adding a third electric vehicle to our fleet.”
