Why NXITY

Complex energy systems demand more than isolated solutions. They require deep system understanding, analytical rigor, and experience from real-world implementation.

NXITY is a Scandinavian-origin consultancy specializing in project management, system analysis, and optimization of integrated energy systems. We support decision-makers across the entire value chain – from early strategy and investment analysis to implementation, operation, and long-term optimization.

What sets NXITY apart is our system perspective. We combine advanced analytical methods, digital tools, and hands-on project experience from hundreds of energy systems worldwide. This enables us to identify what truly matters: performance, resilience, cost efficiency, and long-term sustainability.

We work independently, vendor-neutral, and always with our clients’ objectives at the center. Whether supporting municipalities, energy companies, industry, or financial institutions, our role is the same – to turn complexity into clarity and analysis into action.

NXITY delivers insight you can trust – and results you can build on.

PFC Pro – simulation and optimization

PFC Pro is a powerful tool for simulation and optimization of district heating and district cooling systems. NXITY uses and develops PFC Pro as part of our offering to clients worldwide.
