Flexibility, backed by experience
Managing a diverse portfolio of energy assets often means navigating multiple systems, vendors, and interfaces — making it harder to optimise performance, ensure compliance, or scale efficiently.
RESolve brings everything together in one proven platform. Built on deep operational experience, it delivers real-time control, fleet-wide visibility and advanced diagnostics across storage, solar and hybrid assets. Its modular, vendor-agnostic design provides the flexibility to adapt your fleet to changing market conditions, integrate upgrades, and maintain consistency across geographies and suppliers.
Whether you’re procuring new assets or operating existing ones, RESolve gives you the technical confidence and operational agility to maximise performance and unlock long-term value.
Why RESolve?
RESolve offers a flexible, scalable energy management solution that adapts to your needs across BESS, Solar PV, and hybrid sites. Whether managing a single system or an entire fleet, it unlocks long-term value by optimising performance, ensuring compliance, and future-proofing your assets.
Backed by experience
We offer integration services built upon on decade of experience across global markets. Our engineering services can ensure your site is designed properly, and our commissioning service ensure you enter the market on time.
Secure grid access
RESolve’s integrated Power Plant Controller ensures compliance with evolving grid requirements, even on weaker connections. It regulates voltage and frequency to maintain system stability and support secure grid interconnection.
Total system flexibility
Built on open, off-the-shelf industrial automation hardware, RESolve avoids vendor lock-in and gives you the freedom to choose components that fit your strategy. Add new batteries or technologies without the need for costly redesigns.
One platform, full control
With both on-site and remote access, RESolve standardises monitoring, reporting and dispatch across all assets. Operators benefit from intuitive interfaces — including an HMI for on-the-ground control and a cloud-based GUI for fleet-level oversight.
Proven and trusted
RESolve builds on over 450 MW of global RES construction and more than 127 project-years of operational experience. Our teams provide hands-on support for integration, commissioning and lifecycle evolution — so your assets keep performing at their best.
Key system components
Behind RESolve’s performance is a suite of powerful, flexible tools designed to maximise control, integration and insight across your energy assets. From real-time optimisation to future-ready scalability, each component works together to deliver the visibility, compliance and efficiency your sites need.
Power Plant Controller (PPC)
Our Power Plant Controller provides real-time coordination and control of all assets within a power plant to ensure grid code compliance and power quality. By regulating voltage and frequency, it maintains grid stability and executes setpoints from the Energy Management System (EMS). Supporting seamless integration, the PPC enables your project to meet interconnection requirements with confidence and precision.
Energy Management System (EMS)
At the heart of every RESolve deployment, the EMS Core acts as the brain of your energy system - bringing together hardware, software and communications to manage real-time energy flow across your assets. Designed for seamless OEM integration, it enables flexible augmentation and precise control across both AC and DC architectures, balancing system performance and supporting future expansion with ease.
Advanced EMS
Our Advanced EMS applies intelligent control to optimise the performance of Distributed Energy Resources (DERs). By integrating, dispatching and scheduling your site operations, it ensures grid stability while adapting to changing market conditions. With modular features designed to deliver maximum efficiency, it supports ancillary services, smart scheduling, and custom algorithms to unlock new revenue streams and future-proof your energy assets.
Graphical User Interface (GUI) and Human Machine Interface (HMI)
RESolve offers intuitive control at every level. The GUI enables remote access, from fleet-wide views down to individual cells, supporting real-time operations, asset planning and scheduling. Onsite, the HMI provides immediate visibility with direct hardware access, allowing operators to monitor data, manage performance and respond swiftly to asset conditions.
