NOVA demonstrator launches first prototype for testing

The National Digital Twin Programme (NDTP) has released the first prototype of NOVA, a renewable energy planning demonstrator designed to explore how digital tools can support the integration of renewable energy assets into the UK’s energy system.

Like other NDTP demonstrators, the concept for NOVA was first explored on the Isle of Wight, where local stakeholders have contributed their time, expertise, and feedback. This early collaboration has been instrumental in shaping the direction of the tool and in identifying features that could have value both locally and nationally.

This initial version is intentionally simple, focusing on a single asset type with a small set of data layers. It enables users to choose a location, apply environmental and infrastructure constraints, view a heat map showing suitability, position a renewable asset in 3D, and connect it to the grid using available substation data. While limited in scope, this prototype serves as a proof of concept to illustrate how a more capable tool could operate as development progresses.

NOVA is designed to work with the NDTP Integration Architecture, which means it can take advantage of established patterns, interfaces, and data exchange methods developed through other demonstrators. This approach speeds up delivery, ensures consistency across projects, and captures lessons that will feed into future technical products, documentation, and open playbooks.

Although the current version models only wind assets, future iterations are expected to incorporate solar, tidal, and battery storage, along with more advanced grid connectivity features and richer datasets. As the prototype evolves, it will also explore the integration of real-time data, supporting more dynamic simulation and planning. Feedback from this testing phase will help determine the most valuable next steps and guide development towards a nationally scalable solution.

A recorded walkthrough of version 0.9 is available below, offering a preview of the current capabilities and intended user journey.
