BESS & Microgrids
Energy under control. BESS and microgrid solutions that deliver, every time.
Waarom Zwart?
A Battery Energy Storage System (BESS) is never a standalone solution. The true value of battery storage is realised when generation, storage, consumption, grid connection and energy management work together seamlessly. Where continuity is critical, backup power systems provide additional protection against power outages.
This requires a partner that understands the complete energy ecosystem and remains involved long after commissioning.
Proven quality
With more than 95 years of experience in critical infrastructure, we operate in environments where safety, reliability and performance cannot be compromised.
Tailored solutions
No two sites are the same. Every system is designed around the specific infrastructure, operational requirements and energy profile of each location.
Everything under one roof
From engineering and procurement through to construction and commissioning, a dedicated team manages every stage of the project.
Beheer & onderhoud
Our in-house service and maintenance team provides remote monitoring and 24/7 support, ensuring reliable long-term performance.
One integrated energy system
The right energy solution starts with understanding how energy is used in practice. How is energy generated? Where do peak loads occur? How much capacity is available through the existing grid connection?
As a system integrator, Zwart brings these elements together within a single, optimised system architecture. We integrate battery storage, generation assets, energy consumption, energy management and grid infrastructure into one coordinated solution. Control systems, communications and cybersecurity are aligned to ensure reliable operation.
We work independently of manufacturers, allowing every configuration to be selected on technical merit and aligned with the site's energy profile, operational requirements and long-term objectives.
The result is not an off-the-shelf solution, but an energy system that works in the real world; making smarter use of available energy and grid capacity whilst providing the flexibility to adapt to future developments.

Greater control over energy
Wat levert een geïntegreerd energiesysteem op?
Een goed geïntegreerd energiesysteem doet meer dan alleen energie opslaan. Het helpt beschikbare energie en netcapaciteit slimmer te benutten, pieken op te vangen en vraag en aanbod beter op elkaar af te stemmen.
Zo ontstaat ruimte voor een duurzame energievoorziening die meebeweegt met veranderende behoeften en toekomstige ontwikkelingen. Energie slimmer inzetten, netcapaciteit optimaal benutten en bouwen aan een toekomstbestendige energievoorziening.
Zwart zorgt voor een oplossing die technisch klopt en economisch werkt.

Our process
Analysis & consultancy
We assess energy consumption, generation assets, grid capacity and future growth plans. This includes feasibility studies, business case development, payback calculations and subsidy opportunities.
System design & hardware
From battery energy storage and Energy Management Systems (EMS) to solar PV, CHP installations and backup generators. The right technology, engineered for safe and reliable integration.
Turnkey delivery
Engineering, installation, integration and project management delivered through a single experienced partner, with one point of contact throughout the project.
Smart energy management
Advanced Energy Management Systems optimise capacity utilisation through peak shaving, load balancing, grid monitoring and real-time control.
Energy optimisation
We help unlock additional value from energy assets. By participating in balancing markets and flexibility services, stored energy can generate additional revenue streams and strengthen the project business case.
Service & maintenance
Preventive maintenance, corrective support, continuous monitoring and 24/7 assistance ensure long-term system reliability and availability.
