A '''battery energy storage system (BESS)''' is a combination of a [[battery]], power inverters, battery management system (BMS) and energy management system EMS. Other components may include: thermal regulation system,fire protection, electric protection, transformers. The goal is to provides energy services. Large and/or BESS may require electrical technician to maintain the electrical instalaltions and an operator for the energy management system/SCADA.

== Roles ==

The role of the BESS is store and release energy in order to provide services while respecting constraints. Some services may be competing and other complementary. This problem can be formulated as a mathematical optimization problem.

Services can be grouped in various category:
* emergency power and off-grid operation
* maximizing consumption of locally produced energy
* ensuring balance of supply and demand at various time- and geographical time-scales: energy arbitrage (aka time of use), frequency regulation
* ensuring the transmission capacity of the national, regional, or local grid are respected. This includes capacity tariffs in Europe (know as demand charge in the US), contractual power, grid upgrade def feral.
* power quality. Ensuring voltage and reactive power are within operating limits.

These services may be more or less mature depending on the country and local situation.

 The role of the BESS is store and release energy in order to provide services while respecting constraints. Some services may be competing and other complementary. This problem can be formulated as a mathematical optimization problem.
 Services can be grouped in various category:
 * emergency power and off-grid operation
-* maximizing consumption of locally produced energy
+* black start
-* ensuring balance of supply and demand at various time- and geographical time-scales: energy arbitrage (aka time of use), imbalance reduction, frequency regulation
+* maximizing consumption of locally produced energy and reducing curtailment of locally produced energy.
 ** energy arbitrage (or time of use), in Europe this can be traded on power exchanges (e.g. Nordex, Epex) via day-ahead and intra-day prices or via dynamic energy contract (in this case the energy supplier will trade directly or indirectly on the power exchanges.
 * ensuring the transmission capacity of the national, regional, or local grid are respected. This includes capacity tariffs in Europe (know as demand charge in the US), contractual power, grid upgrade def feral.
