Project Overview Image

Project Overview

Design of a capacity-constrained EV charging scheme where the proposed charging infrastructure required significantly more power than the available network capacity. The design response combined Battery Energy Storage System (BESS), Solar PV generation and intelligent load management to maximise charging capability within the available grid constraint.

Challenges

01

Insufficient grid capacity

The proposed EV charging infrastructure required significantly more power than the existing network could provide.
02

Renewable energy requirement

The scheme needed to increase the contribution of locally generated renewable energy.
03

Import limit and peak demand risk

Peak charging periods created a risk of exceeding DNO import limits.
04

Night-time operation

The site needed reliable charging capability when solar generation was unavailable.
05

Efficient use of available space

The design needed to make effective use of the site area while supporting renewable generation.

DACI Solution

1. Integrated energy solution

BESS, Solar PV and load management were used to supplement the limited network supply.

2. Solar PV canopies

Solar canopies were installed above parking spaces to generate clean energy on site.

3. Dynamic charger load management

Dynamic load management was introduced to control charging demand within the agreed limits.

4. Stored energy and controlled import

Controlled grid import was combined with stored battery energy to maintain operation.

5. Multi-purpose canopy arrangement

Solar canopies generated renewable energy while also providing sheltered parking facilities.

Outcome

The integrated BESS, Solar PV and load management strategy transformed a capacity-constrained location into a viable and scalable EV charging hub. The solution maximised locally generated renewable energy, reduced reliance on the grid and maintained compliance with network import limits without depending on reinforcement works. It provides a repeatable model for delivering EV charging infrastructure where network capacity would otherwise restrict development.
