Two cases makes out:
Current technical, economic and regulatory changes are driving the growth of new local models at individual or community levels. Self-consumption growth is therefore driven by:
All these conditions have contributed to the growth of a self-consumption sector in France that, while still modest, is growing strongly.

The effect of self-consumption on the grid differs according to whether it is individual or collective. Conversely to collective self-consumption, individual self-consumed energy does not transit by the public grid.
For individual self-consumers, nothing currently economically justifies a specific withdrawal component compared to that used for other consumers.
TURPE tariffs nevertheless cater for the growth of self-consumption, as with any new use of the public grid. The CRE checks that tariffs are effective and robust enough to change behaviour and subsequently, adjust the grid costs generated, leading to progress in consistent invoicing, regardless of electricity use.
In terms of collective self-consumption, the main challenge is making certain low-voltage transit flows financially worthwhile. Collective self-consumption can, if correctly proportioned and managed, be of value to the electricity system.
The CRE has therefore introduced a new tariff, matching the effects consumers are having on the grid. It does this by applying different rates to low-voltage and high-voltage transit flows (conventional consumers pay for costs generated by average flows)
A specific management component is applied to individual and collective 'self-consumers’ that reflects their more complex management costs.
The CRE presented its recommendations and guidelines on self-consumption-related subjects in its deliberation of 15 February 2018.
Its recommendations and guidelines for support mechanisms and a contractual framework respectively seek to:
