Rules forbidding RES energy curtailment except for security issues
Currently only an exception.
Curtailing small quantities of energy could increase significantly the hosting capacity of PV.
Analyze whether slightly increasing the conditions could be beneficial.
Compensate the PV agent for the curtailment.

Incoherent Metering Framework
Foster a quicker implementation of some of the technical solutions.
Directive 2009/72/EC Target 80% for 2020 Directive 2009/72/EC. Target 80% for 2020 depending on a cost benefit analysis.
Required not only for consumers, but also for the photovoltaic installations

Regulatory Frameworks that do not Incentivise “Smart Grid” Development
Communication infrastructures.
Favor technologies with high potential impact and good readiness which find regulatoryand good readiness, which find regulatory barriers.
DSO should be incentivized for using smart solutions instead of just conventional solutions.
A regulatory framework.

DSO investments recovery
1) Avoid that the DSO have an excessive delayPrevent at least a financial risk of DSO.
2) Ens re DSOs are rem nerated b the efficient in estments2) Ensure DSOs are remunerated by the efficient investments.

Insufficient Framework for Prosumer Storage Solutions
1) Prosumer storage solutions should be regulated and allowed.
Ensure not posing the system into a security problem or interfering with the metering.
2) Establish mechanisms for incentivising the storage solutions, when applied to reduce the peaks of PV installations.

Regulatory Frameworks that do not Incentivise “Smart Grid” Development
1) Adaptation of national regulatory frameworks to promote “Smart Grid” investments
A stable and transparent regulatory framework
Where necessary, explicit incentives should also be established:
To innovative projects in smart grids or generalized.
