Where is this house situated?
The house of the future
Energy bill of the future
• Evolution grid tariffs (per region)?
• Capacity based tariffs
• Injection tariffs
• Amount of the total DSO costs
• Evolution of the taxes?
• Evolution of the commodity prices?

Market Research – Eneco (1/2)
Do you find the concept of energy storage interesting?
• To be able to use stored solar energy during off-peak hours• (more) independance from the net• To be able to choose when to consume energy• To avoid high grid costs
Market Research – Eneco (2/2)
How appealing is this concept at a price of 5.000€?
In real life - setup

Conclusion
• Batteries will be part of the house of the future
• Eneco can add more use cases to the battery (with regulatory
changes)
• 30% of solar PV owners are starting to get interested at a
price of 5.000€, we need more effort to get below this price
