Photograph of five windmills on a grassy field next to water. The photo is taken from a perspective where the first mill looks significantly bigger than the second one, etc, until the last windmill in the distance. There sky above is filled with clouds.

Focus of the text

This article presents an overview of frameworks for how to scale demonstrator projects into fully operational solutions, in order to create large-scale impact. Project managers of demonstrator projects, managers of proposal projects and other stakeholders will benefit from the text.

Scaling is essential, but also very challenging. Learn more about recommendations and frameworks that will help you successfully scale your heating and cooling demonstrator projects.

As indicated by the many successful demonstrator projects within Celsius, there are many technical solutions that would provide a positive and sustainable impact if they were scaled and replicated. However, it is not easy to go from an innovative but fairly small demonstrator project – with many “bells and whistles” and a design based on an estimated lifespan of a few years – to something that is much larger in capacity and magnitude, and developed to be up and running for decades. Furthermore, it is not so simple to replicate such solutions , since the contexts differ within companies and cities, and the differences may be even larger when it comes to replications from other cities, regions and countries.

Celsius has developed a list of recommendations for what to consider when either planning a demonstration project or planning the next step at the end of a demonstration project. The list can be found here. The recommendations are all based on the notion that in order for a new concept to make an impact, it needs to be implemented on a large scale, and this requires funding. There is little chance of getting funding using only technical data, especially when it comes to loans, which is why information on other aspects must  be gathered early. The recommendations are presented as a checklist, covering the following areas:

  • Funding
  • Politics and policy
  • Team and competence
  • Regulations
  • Risk management
  • Community Acceptance and User involvement
  • Business Models
  • Technology

These areas are also similar to the EIT Climate KIC:s four major categories of “Enablers of Change” , which focus on city transformation:

Collaborative communities
  • Citizen Co-Creation
  • Alliances and Partnerships
  •  Collective Management
Enabling economies
  • Business Models
  • Capital Alignment
  • Market Structures
Municipal momentum
  • Active Democracy
  • Catalytic Policy & Procurement
  • Municipalities Tuned for Change
Smarter systems
  • Governance of data
  • Interoperability
  • Smart Applications

There are also other useful frameworks, for example the Scalability and Replicability Analysis (SRA) launched by BRIDGE. Here they make use of the Smart Grid Architecture Model, indicating several dimensions and aspects that need to be considered. These aspects include:


  • Interoperability layers: eg. component, communication, information, function and business.
  • Domains: eg. generation, transmission, distribution, distributed energy resources, and customer premise.
  • Zones: eg. process, field, station, operation, enterprise and market.
