“Nett always acts on data, making Belmap the perfect source”

To identify available rooftops for solar panels, green-energy supplier Nett chose Belmap as its new data source and GIM as a reliable data partner.

In the field of solar energy, Flanders still has a significant amount of unused capacity. Using Belmap, energy provider Nett is able to power its market strategy, and track down all available rooftops in an instant. Arthur Despiegelaere, CEO: “We can identify and target our ideal clients in just a few clicks.”

Exploiting untapped capacity

Studies indicate that only 8% of rooftops in Flanders are equipped with solar panels. Many roofs remain unused because local energy consumption is often too low to justify the investment. “At Nett, a green-energy supplier, we want to exploit this untapped capacity”, says CEO Arthur Despiegelaere. “And that's without SMEs having to invest in a solar farm themselves or be responsible for their own operational management.”

Instead, in exchange for the use of their roof, Nett offers small business owners green power for 25 years. “And those without a roof get green power from entrepreneurs with some to spare,” Arthur continues. “Companies with shortages can expand their ‘virtual’ rooftop area by generating power on nearby unused rooftops.”

Identify and target clients in just a few clicks

For this approach to succeed, Nett needs roofs. Lots and lots of roofs. And that's where Belmap comes in. Arthur: “Belmap is the most complete address and building reference file in the Benelux, and it is updated daily. It also includes useful information such as: the age of the building, presence or absence of solar panels, roof surface and type, probability of asbestos and so on. Very valuable in the context of prospecting.”

The solution that emerged was relies on Belmap’s powerful querying function. “We chose an offline address enrichment where GIM selected addresses of business establishments from their extensive Belmap database in line with our selection criteria. The completeness, granularity, modularity and area coverage of Belmap product were decisive for us to partner with GIM. In just a few clicks, we can identify and target our ideal customers.”

Fast and professional

Lastly, it was also important to Nett for their data partner to be flexible and to share ideas. “Double check!”, concludes Arthur. “We feel fully supported by their fast approach and broad expertise. If we want to expand our dataset in the future, we are in the right place with GIM and Belmap.”
