Floating Photovoltaic Plant ‘Sibelco’
Duration: 6-month
Consortium: Luminus, Sweco and Sibelco
Support: € 50.000
Key questions:
• Can a floating PV plant (5MW) on the Sibelco site
in Dessel be financially viable?
• Can the ecological impact be minimized?
• Can we outline guidelines on the licensing
of floating PV parks?
Factual update
Kristof Vanhoorne: “The study showed that the impact of floating solar parks on fauna and flora is negligible,
when installed on waters deeper than 5 meters. To safeguard a landing strip for waterbirds, it should be
discouraged to cover the complete water surface.
EDF’s R&D department modelled and compared several innovative solutions (e.g. the use of bifacial panels,
Azimuth tracking, Albedo-reflection, active cooling) to maximize the efficiency of the solar panels, hoping to
bring it to 10%. Our study showed, however, that one has to be cautious with these assumptions. The efficiency
of floating solar panels is often assumed to be 3 to 5% higher than land-based panels, due to the water’s cooling
effect. Tests by Luminus showed a mere 1% increase.
In Flanders, 5560 hectares are suitable for the installment of floating PV parks. Together, they could account
for 500 MW. The business case is strongest on sites where self-consumption exceeds 60%, this is however
rarely the case as most large bodies of water occur in nature parks.”

Connected Buildings
Duration: 6-month
Consortium: June, Engie, EnergyVille and Insaver
Support: € 48.521
Key questions:
• Can we identify innovative energy services for
residential users by analyzing real-time energy data
recorded by low-cost sensors and other IoT-data
services?
• Can tailored ‘total package solutions’ based on
connectivity in residential buildings provide customers
with higher comfort and significant energy- and
cost savings?
Factual update
Vincent De Dobbeleer: “Market research among June’s 7,000+ customers showed that users are open to the
expected benefits of new technologies like IoT and AI. Users confirmed a willingness to pay for data-driven,
cost-efficient energy services.
In the feasibility study, a collaboration model - between customers, June and energy suppliers & installers –
and an implementation plan was defined. When sensors are placed in a residential building in connection with
a data-driven platform for collecting, combining and analyzing data, it becomes possible to perform an automated
energy-audit, resulting in customized smart energy insights.
The financial plan turned out positive, because data-driven energy advice leads to higher trust and accuracy,
allowing installers to improve customers’ lifetime value.”

Smart Business Area of the Future
Duration: 10-month
Consortium: ENGIE Electrabel, Quares, Continental & Intervest
Support: € 50.000
Key questions:
• Can a group of 4 businesses, located in the Mechelen
Noord business park, form a LEC (Local Energy
Community), to interchange energy and guarantee a
more stable network for the grid operator?
• Can storage capacity of electric vehicles, in combination
with local energy storage, be used as a reliable peak
power station?
Factual update
Mia Van Daele: “The aim is to create a microgrid living lab for a LEC with a real-time optimization of renewable
energy generation, flexibility in load, local storage and green mobility. Such a living lab has to prove cost-efficien-
cy, flexibility and reliability.
For each participant in a LEC, an optimal ‘energy profile’ is made. After a one-year study period of the site in
Mechelen - consisting of an analysis of the current situation, a technical feasibility study, an outline of the energy
management, the creation of a business model and an investigation of the legal aspects - we are now moving on
to the creation of the living lab. This involves measuring energy flows, investing in renewable energy and storage
and making financial optimizations.”
Next steps & challenges
Van Daele: “The LEC in Mechelen Noord needs room to

Microgrid Services for local Communities
Duration: 7-month
Consortium: ABB and Enervalis (technical players), KBC (financer), EnergyVille (research partner) & Fluvius
Support: € 41.935
Key questions:
• Can we describe the role of an energy community service provider or ‘Energy Lessor’ in the Local Energy
Community (LEC) on the Keerdoksite at the Rode Kruisplein in Mechelen?
• Can the Energy Lessor offer the LEC an all-in managed energy package, including the energy assets itself
and servicing over the entire lifecycle, at a price that is no higher than the usual alternatives, and with
minimal environmental impact.
• Can the Energy Lessor enable the LEC to act as a viable participant in the energy transition, by taking the
cost of the energy management out of the development project and offer it to the LEC separately?
Factual update
Jelle Meersman: “The project was completed in January
2018. A two-page summary, several presentations and
a paper were made available to disseminate the results.
The target group of MSLEC consisted of major urban re- “The project came up with

Initial reactions were positive. It was felt that the Energy Lessor will bring scale and expertise to local energy
communities by ensuring that the costs and benefits of a future-oriented energy system are synchronized
from CAPEX to OPEX. However, a high level of participation (from owners/tenants) in the LEC and the imple-
mentation of a tariff structure for LEC’s in the Clean Energy Package are considered important success factors.”
Next steps & challenges
Meersman: “With the role of the Energy Lessor defined and the
business model in place, it is now time to put things into practice.
The ICON-project ROLECS (Roll-out of Local Energy Communities)
was set up to this end. If the model proves to be successful in the
field, it can easily be replicated for all large-scale real-estate
projects for which construction has yet to begin. In time, replication
in other market segments (like the renovation market) is possible.”
Smart Multi-Energy District
Duration: 6-month
Consortium: DuCoop, Enervalis, ABB, Imec & SF1 Services
Support: € 49.840
Key questions:
• Can we design a smart multi-energy district with a
heating network, decentralized wastewater treatment,
sustainable mobility and connectivity on 3 levels:
living space, work space and community space?
Starting point is brownfield De Nieuwe Dokken in
Ghent, which consists of 400 homes and a number
of commercial spaces and public facilities.
• Can a data platform meet the strict data needs for
demand side management in a LEC?
• Can we make a promising value network?
“Politics and regulation remain
hurdles, for example when it
comes to the tariff structure
and subsidy mechanisms for
LECs or the roll-out of direct
line connections on public
domain.”
Peter De Smet, Director, Clean Energy Invest
De Nieuwe Dokken
Factual update
Peter De Smet: “The public facilities at De Nieuwe
Dokken will open in the summer of 2019. By the
end of the year, people will be living in the district.
So far, gateways have been installed in 70 home
units and a district-wide IT-network is in place.
Also, a district-wide PV-network with battery storage
is on the agenda. As of June 2019, the district will
have its own medium voltage cabinet. We intend
to put in place a private direct line connection
between the construction zones.

De Vlaamse Staak
Duration: 8-month
Consortium: Th!nk E, Wattson and Viessmann (in close
collaboration with Powerdale, POM Vlaams-Brabant, ge-
meente Opwijk and Intercommunale Haviland)
Support: € 50.000
Key questions:
• Can we develop a sustainable energy concept that
might be useful for new developed SME business
parks, such as ‘De Vlaamse Staak’ in Opwijk?
• Can decentralized heat pumps fed by local sustainable
electricity sources serve as an alternative for a
natural gas network?
Factual update
Antoon Soete: “In May 2019, 11 of the 15 lots on business park De Vlaamse Staak were allocated. The first
building activities are scheduled for the end of this year. It has been clear from the start that a traditional
heating network is not an option at De Vlaamse Staak. Still, the SME’s need thermal comfort at a competitive
price. Therefore, we decided on a phased approach. In Phase 1 (from 2019 to the end of 2020) all SME’s will
get a heat pump and solar panels, and their own connection to the Fluvius grid. In Phase 2 (as of 2021) De
Vlaamse Staak will hopefully evolve into a Local Energy Community (LEC) resulting in additional renewable
capacity by installing a medium-sized wind turbine on site.
The feasibility study showed that at present natural gas remains the unsurpassed energy vector. There was a

Green Energy Park
In Zellik, on July 4th, the Green Energy Park by VUB and UZ Brussels was officially launched.
Support: € 295.000
No less than 6 feasibility studies provided the foundations for this unique living lab, which integrates an
electric and a thermal grid. Following the results of the financial analysis, it was decided to start with a
smaller testing ground, that can easily be upscaled in the future.

Green Energy Park Factual update Maarten Messagie: “The trajectory was very successful. A 120-page final report on the six projects is now available. More importantly, the follow-up to the studies is guaranteed by three ICON-projects: MaMûet (Machine learning for real-time advanced multi-energy trading – led by VUB), Optibids (Optimized bi-directional & smart-vehicle charging in local energy systems - led by VUB) and ROLECS (Roll-out of local energy communities - coordinated by Th!nk E). Another positive result of the feasibility studies is that the MOBI Research Centre was able to start a new research unit, EVERGi, that aims to be the catalyst that brings interdisciplinary science together with industrial innovation to fully support the energy transition. EVERGi was able to leverage the support of VLAIO and FLUX50 on a European level and bring several Horizon2020 and Interreg projects to Flanders. The EVERGi team has gone from 3 to 20 FTE’s on the payroll. EVERGi is specifically concerned with climate change and air pollution. We are working at the crossroads of two extremely important transi- tions – namely energy and mobility. Therefore, a demonstrator living lab and a co-creation ecosystem platform are indispensable.”. Next steps & challenges Jimmy Van Moer: “Two important challenges that come with feasibility studies and project proposals are the huge administrative burden and the intensive communication with all stakeholders. This is especially true for European projects, where the red tape seems endless, while they only provide 40% of the funding, leaving you with quite an amount to gather elsewhere.”
Enhancing Multi-Energy Distribution
in large Retail Development
Duration: 5-month
Consortium: ABB, Enervalis, Antea Group and Quares
Support: € 48.872
Key questions:
• Can retail development fit in a larger multi-energy network that consists of several clusters with their
own energy demand and generation?
• Can we develop a design tool for grid-layout through AI clustering techniques that retail developers
such as Quares use to evaluate several options early in the development process and set up an econo-
mic business case?
• Can we create a tool to define the optimal scenario (all-electric, district heating or domestic heating)
for a site such as the Graaf Karel de Goedelaan in Kortrijk?
