Central theme across nearly all projects: FLEXYNETS (5th-gen networks), CoolHeating, HRE, HotMaps, RES-DHC, and SDHp2m all focus on DH&C planning, deployment, or transformation.
PLANENERGI FOND
Danish district heating specialists contributing renewable thermal energy planning, solar DH, and storage expertise to European energy transition projects.
Their core work
PlanEnergi Fond is a Danish energy planning organization specialized in district heating and cooling systems, with deep expertise in integrating renewable energy sources into urban and community-scale thermal networks. They provide technical knowledge on solar district heating, thermal energy storage, and heating/cooling system transformation — bridging the gap between energy policy planning and practical deployment. Their work spans from strategic heat roadmapping at national level to hands-on tool development for local energy planners and municipalities.
What they specialise in
SDHp2m focused on mobilizing solar DH investments; CHESTER explored solar district heating with thermal storage; CoolHeating addressed small modular renewable DH grids.
CHESTER investigated pumped thermal energy storage and power-to-heat-to-power concepts; FLEXYNETS explored low-temperature network designs enabling storage integration.
HRE developed national heating and cooling strategies; HotMaps created open-source mapping and planning tools; SDHp2m advanced policies for solar DH market uptake.
SmartEnCity (their largest funding at EUR 474K) targeted smart zero-CO2 cities, applying their thermal expertise to broader urban energy system transformation.
RES-DHC (2020-2023) explicitly targets fossil-to-renewable transformation of DH&C systems with sector coupling; CHESTER explored power-to-heat-to-power integration.
How they've shifted over time
PlanEnergi Fond's early H2020 work (2015-2018) concentrated on designing next-generation district heating networks and building the policy and market frameworks to support them — projects like FLEXYNETS, CoolHeating, SDHp2m, and HRE were about mapping, planning, and proving the case for renewable district heating. From 2018 onward, their focus shifted toward energy storage, sector coupling, and the practical transformation of existing fossil-based systems to renewables, as seen in CHESTER and RES-DHC. This evolution mirrors the broader European energy transition: from "what should we build?" to "how do we convert what already exists?"
Moving from planning and advocacy toward hands-on decarbonization of existing heating infrastructure, with growing interest in thermal storage and sector coupling — making them a strong partner for projects tackling real-world fossil phase-out in district energy.
How they like to work
PlanEnergi Fond operates exclusively as a participant, never coordinating — suggesting they contribute specialized technical or advisory knowledge rather than leading large consortia. With 114 unique partners across 20 countries from just 8 projects, they work in large, diverse European consortia and appear comfortable integrating into complex multi-partner setups. Their consistent participation in CSA (coordination and support) projects indicates they often play an advisory, capacity-building, or knowledge-transfer role.
Extensive European network with 114 unique consortium partners across 20 countries, built through 8 projects — an unusually wide reach for an organization of this size. Their network is strongly centered on Northern and Central European energy planning institutions, reflecting Denmark's leadership in district heating.
What sets them apart
PlanEnergi Fond brings Denmark's world-leading district heating expertise into European consortia — Denmark has the most mature DH infrastructure in Europe, and this organization has been embedded in that ecosystem. Their combination of technical knowledge (thermal storage, solar DH, low-temperature networks) with policy and market uptake experience makes them a rare bridge between engineering and deployment. For consortium builders, they offer a credible Danish DH voice without the overhead of a large research institution.
Highlights from their portfolio
- CHESTERTheir largest single grant (EUR 491K), exploring the intersection of compressed heat energy storage with solar district heating — a technically ambitious project combining their core DH expertise with emerging storage technology.
- SmartEnCityTheir longest-running project (2016-2022) and second-largest funding (EUR 474K), extending their thermal expertise into full smart city energy system integration across European cities.
- HREHeat Roadmap Europe was a flagship policy project that shaped national heating and cooling strategies across the EU — high-visibility work that positioned PlanEnergi in the European energy policy conversation.
