“People are starting to realize energy storage isn’t just a project or two
here or there, it’s a whole new approach to managing power,” said John
Zahurancik, COO at Fluence

5. There are 10 major storage system design considerations (1/2)

A number of interacting parameters influence the optimal design of a BESS solution
1.Project Size; larger, longer duration projects typically have improved economies of
scale and deployment efficiency.
2.Use Case; the expected system use(s) directly affects system degradation. More
throughput (energy in/out) increases degradation as does a higher resting State of
Charge; both in a non-linear manner. Understanding use case is critical to selecting
an appropriate battery chemistry; simple ‘cycle’ numbers do not capture this.
3.Firm Capacity Requirements; if there is a requirement to compensate for battery
degradation and maintain a rated system duration this can be achieved by either
overbuilding the system up front with additional batteries or building in additional
space to augment the system with additional batteries through O&M (or a
combination); both can increase costs of CAPEX and OPEX and depend on length of
the firm capacity requirements and the use case. After the firm capacity period ends
the system is still useable but the MWh capacity will begin to degrade in accordance
with the way it is used.
4.Performance Requirements; maintaining a higher technical availability requires
more battery and/or inverter redundancy which can increase costs and influence
deployment architecture; Technical Availabilities of 96-97% are typical.

6. There are 10 major storage system design considerations (2/2)

A large number of interacting parameters influence the optimal design of a BESS solution
5.Power Factor; providing rated power at less than a unity power factor requires
more batteries/inverters to achieve. A typical value is 0.95.
6.Undervoltage;providing full rated power at a lower voltage requires more
batteries/inverters to achieve. Typically, undervoltage is dealt with via a On
Load Tap Changer upstream of the BESS and a p.u. of 1 is assumed.
7.Point of Metering; Losses increase with distance from batteries. An energy
storage system must be overbuilt to account for these losses. Typically for EPC
solution performance is measured at PCC to grid, for a ‘Core’ sale it is
measured at the LV board before the isolation transformers step up to
medium voltage and 1.25% losses are assumed.
8.Auxiliary loads;these are usually separately metered and supplied; if system
output needs to be rated at a certain number of MW inclusiveof aux load this
requires more hardware (batteries, inverters etc.) and thus adds to cost.
9.Environment; for instance, dealing with harsh climates (for instance corrosive
salty air, seismic fault zones, temperature or humidity extremes, flooding,
storm/hurricane zones) may all influence the design requirements and price.
10.Location; local legislation, site accessibility (quality of access roads, turning
arcs, overhead restrictions), shipping, local labour and productivity rates all
factor into system design and project cost.
