Battery Storage

Working with you to create an efficient, low-cost and low-carbon energy system

Solar power captures large amounts of energy during daylight hours. Battery storage helps to better manage energy consumption and make usage more efficient. 

Custom Solar designs, installs and maintains battery storage solutions, working with you to create an efficient, low-cost and low-carbon energy system.  

What is battery storage? 

Battery storage enables your business to take advantage of electricity produced by on-site solar power, in addition to receiving benefits from a number of grid-balancing initiatives. This can reduce tariffs or charges and ensures you are making the most of these benefits: 

Demand shifting 

Your battery can be a source of energy during late afternoon and early evening (red band) periods, avoiding red band charges. This is dependent on the operation and system needs, and our engineers will correctly size a suitable battery, ensuring you can make the most of this demand shift. 

Reduce DUoS (Distribution Use of System) charging 

By reducing peak transmission volume, you can reduce network distribution charges and make significant savings. If you are a large energy user during the red band period, you may be familiar with triad fees. By reducing DUoS charges you are less likely to be hit with triad fees. 

Pricing arbitrage 

Depending on your battery operator strategy, you may see the benefit in charging your battery with excess solar generation, rather than exporting the same energy to the grid at the export rate. This approach would forego the export tariff during periods where energy is more expensive. Similarly, you can buy and sell excess energy from the grid via ‘frequency response’ mechanisms, which our consultants can discuss with you. 

Energy demand management 

A solar battery supports your solar installation, helping to avoid dips or spikes in generation and usage. During periods of lower consumption, the battery will store excess electricity, ensuring that when demand spikes, your system will supply uninterrupted power.
