Battery Storage for Commercial Buildings
The Smartest Way to Reduce Energy Costs and Protect Your Power Supply.
Engineered by Pretium Synergy for organisations that demand performance, stability and long term value.
Store low cost electricity — or surplus solar — and use it exactly when your building needs it most.
With a Commercial & Industrial BESS, you cut operating costs, strengthen resilience, and avoid expensive grid upgrades, all while gaining total control over how and when you use energy.
A Strategic Asset for Forward Thinking Organisations
- Reduce energy bills with intelligent load shifting and peak shaving
- Maximise the value of Solar PV with high self consumption
- Avoid costly DNO upgrades and transformer reinforcements
- Maintain stability with automated EMS driven optimisation
- Increase resilience across mission critical operations
This is energy on your terms — efficient, predictable and built for the future of your organisation.

Why C&I Battery Storage (BESS)?
Cut Peak Costs & Smooth Demand
Charge when tariffs are low; discharge at expensive peak windows (e.g. late afternoon). Reduce DUoS Red-Band charges and transmission related demand costs.
Maximise Solar SelfConsumption
Store surplus PV instead of exporting at lower SEG rates. Use stored energy in evenings, shift transitions, or weekends to lift on-site utilisation.
Improve Resilience
Provide support for critical loads during voltage dips, fluctuations or short outages — offering UPS like capability (design dependent).
Generate Revenue from Flexibility Markets
Participate in frequency response, reserve and balancing markets to earn revenue in addition to savings — “revenue stacking.”
Compelling ROI
With falling storage costs and smarter EMS optimisation, 4–10 year paybacks are increasingly achievable.
Sophistication in Design
Pretium Synergy ensures your BESS is right-sized and right-tuned. We align battery power (kW) and energy (kWh) with:
Core Design Features
Peak-Shave Set-Points
Clip high-value demand spikes while keeping operations stable.
Arbitrage Windows
Charge off-peak (night/weekend); discharge during expensive periods.
Solar Coupling (AC or Hybrid)
Raise self-consumption and reduce export dependency.
Flexibile Scheduling
Reserve capacity for frequency response or reserve services if revenue stacking is desired.
Preferred Chemistry
Chosen for safety, cycle life, stability and commercial suitability. Managed by robust BMS + EMS.
