Are community energy storage systems a good investment?

As previously mentioned, most community energy storage projects in the United States are distribution sited and utility owned. The community indirectly benefits from cost-effective investments that reduce system costs. There is also the potential for distribution sited storage systems to improve local reliability and resiliency.

Does community ownership of energy storage systems matter?

In this context, community ownership and governance of energy storage systems becomes very relevant. Yet, there can be resistance from the incumbent grid operator in providing grid access and for leasing or selling the physical network to the local communities operating CES.

What is shared local energy storage?

Shared local energy storage refers to collective energy storage in a localized community. Although utility scale application of bulk energy storage is common, shared local energy storage are emerging in the energy landscape. For example, since 2015, Feldheim energy community owns 10 MWh CES.

What is an example of a community based energy storage system?

Example: Gridflex Heeten Energy storage of size tens to hundreds of kWh installed in front of the meter and behind the transformer in the local neighborhoods with community ownership and governance as well as shared via the local physical grid. Example: Feldheim energy community

Does community storage reduce exports from the microgrid to the upstream network?

Under the simulated conditions, we find that the optimum storage at the community level was 65% of that at the level of individual households and each kWh of battery installed was 64-94% more e ective at reducing exports from the community microgrid to the upstream network.

Can community applications reduce the life-cycle cost of energy storage?

The community application is demonstrated to reduce the life-cycle cost of energy storage as high as 37% over the individual household application . Some authors, however, report that CES are not yet feasible .
