Storage infrastructure for a more flexible energy system

Large energy projects need storage that can respond to changing generation, demand, network constraints and commercial priorities. AlphaESS utility scale battery energy storage platforms combine high-capacity storage, thermal management, system control and connected monitoring within scalable project architectures. Start with the project objective, connection position and operating strategy. Product selection follows from those requirements.

Storage designed around the role it needs to perform

Renewable integration

Store electricity from solar or wind, then dispatch it in line with network, market or site requirements.

Microgrids

Coordinate generation, storage, loads and generator support within a controlled local energy system.

Grid services

Configure eligible systems around defined network and market services, subject to connection conditions and qualification.

Infrastructure and estates

Develop storage around transport, public-sector, multi-building or strategic infrastructure energy needs.

Large energy users

Use site-scale storage to manage major loads, support energy optimisation and strengthen operational flexibility.

Capacity growth

Use modular or containerised platforms that can be developed around the power and energy requirements of each phase.

Built around the project, not a standard package

A utility scale battery project is shaped by its connection point, operating strategy, duration, revenue model, site conditions and long-term service requirements. The product should be selected only after those requirements are understood.

01
Define the commercial objective, operating strategy and target scale.
02
Review generation, demand, land, connection status and site constraints.
03
Develop the required power, capacity, duration, coupling and controls.
04
Select the appropriate platform and outline the system architecture.
05
Confirm grid, planning, safety, civil, fire, acoustic and environmental requirements.
06
Agree delivery responsibilities, commissioning, monitoring, warranty and lifecycle support.

Choose the platform around the project architecture

ASTER 250/500

A liquid-cooled containerised platform for projects requiring 250 kW to 500 kW output and 705 kWh to 1,410 kWh capacity, subject to UK product approval.

Technology that works as one controlled system

Battery management

Monitor operating conditions, balance cells and apply defined protective thresholds.

Energy management

Coordinate charging, discharging and operating modes around the project strategy.

Thermal management

Maintain operating temperatures through product-specific liquid cooling.

Power conversion

Connect battery output to the approved AC architecture and connection requirements.

Connected monitoring

Provide visibility, alarms and approved data access through the relevant platform and interfaces.

Layered protection

Combine detection, electrical protection and product-specific response measures within the site design.

Safety and compliance are project requirements

Product-level testing is only one part of a utility scale safety case. Siting, separation, access, drainage, fire strategy, ventilation, emergency planning, electrical protection, cybersecurity, commissioning and operating procedures must be developed for the project and agreed with the relevant stakeholders.

FAQs

How does home battery storage work?

A home battery stores electricity for use when you need it. It can store surplus energy generated by solar panels or electricity taken from the grid during lower-cost periods. The stored energy can then power your home when electricity prices are higher, when solar generation is low or, with the appropriate backup equipment, during a power cut.

Do I need solar panels to install a home battery?

No. A home battery can be installed with or without solar panels. A standalone battery can charge from the grid, allowing you to make greater use of lower-cost electricity tariffs. When combined with solar panels, it can store surplus solar energy that might otherwise be exported to the grid.

Can battery storage be added to an existing solar system?

In many cases, yes. The most suitable arrangement will depend on your existing solar system, inverter, electricity usage and the battery being installed. An approved installer can assess your current setup and recommend a compatible solution.

What size home battery do I need?

The right battery capacity depends on how much electricity your household uses, when you use it, whether you have solar panels and what you want the system to achieve. Your installer should review your electricity consumption and future requirements, including electric vehicle charging or heat pump use, before recommending a system.

Will my battery power my home during a power cut?

Yes. AlphaESS offers a Backup Gateway that can keep your home powered if the electricity supply is interrupted. The available backup time will depend on your battery’s charge level, capacity and household electricity use. Your AlphaESS installer can recommend the appropriate system configuration for your home.
