You need energy data such as weather forecasting, renewable energy production, day-ahead or real time market prices, but sourcing and integrating this data within your product is hampered by a lack of industry digitalisation and clarity on costs and usage rights.

You find working with energy clients such as traders, energy communities and utilities designing digital products challenging and expensive.
