Consider the following: 1. Battery storage 2. Biomass generators 3. Fuel cells 4. Rooftop solar photovoltaic units How many of the above are considered “Distributed Energy Resources”?
Explanation
Distributed Energy Resources (DERs) are small-scale units of power generation or storage that are situated closer to the end-users. Let's analyze each option:
* Battery storage: These store energy and can be deployed within the distribution network or at the consumer end, making them DERs.
* Biomass generators: These can be small-scale and located near the biomass source, making them suitable for distributed generation.
* Fuel cells: Similar to biomass generators, fuel cells can be deployed in a decentralized manner, qualifying as DERs.
* Rooftop solar photovoltaic units: These are a classic example of DERs, generating power at the point of consumption.
_Therefore, all four options are considered Distributed Energy Resources._
