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€?

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
