Case Study: Vrijopnaam achieves nationwide access to solar-park green energy without rooftop panels with Mendix

Vrijopnaam Changes the Dutch Energy Market with Aquila’s Smart Software

Vrijopnaam is an independent Dutch energy broker that enables citizens to buy shares in solar parks and consume green energy without installing panels at home. They needed a full-lifecycle, highly automated system to support sales, customer and contract administration, financial settlement and real-time communication with EDSN, but off-the-shelf products were too costly and inflexible for their evolving requirements.

Partnering with Aquila and using Mendix low-code and Agile rapid experimentation, they built a maintenance and customer-facing app in six months with one developer. The platform—now used by 2,000+ customers—automates onboarding, contract initiation, EDSN verification, accounting integration with Exact, and hourly yield reporting via a mobile app; Vrijopnaam continues to iterate monthly, successfully bringing a scalable, disruptive clean-energy subscription model to the Dutch market.
