DNV GL issued a Recommended Practice (DNVGL-RP-0043) on grid-connected energy storage

Guidelines and methods to evaluate, assess and test safety, operation and performance of grid-connected ES

Referencing ISO, IEC and IEEE standards if possible, enhancing where needed

Industry supported: created by consortium of 7 parties, 36 parties involved in review process

Key take-aways

Storage as an

enabler:

For RES

integration,

network support

Costs becoming

commercially

attractive, but

depending on

many aspects

Various projects in

the Netherlands,

breakthrough yet

to come, new

values to be

disclosed

As a relatively new

and complex item,

various examples

of materialised

risks

GRIDSTOR

Recommended

Practice as the

technical

Behind the meter: Post- net metering

26

Replacing net-metering regulation by a 'feed-insubsidy' of which the height can be reduced stepwise over time.

Starting point for this arrangement is the continuation of investment certainty (pay-back time PV installation of 5-7 years) and the stimulance of momentaneous energy usage

Furthermore:

Dynamic pricing for end-users

Dynamic tariffs distribution grids

Customer-led storage
