Project: T213700 #3142

The objectives of this project are to find out, from other owners and/or operators of BESS, how they are implemented and operated. The main areas of interest are:

  • The types of ancillary services BESS can provide (e.g., black start, operating reserve, fast frequency response, etc.) and how these services are offered
  • In case of a BESS justified and installed as a transmission asset for peak load shaving, how do they participate in ancillary services and handle charging with respect to time and price?
  • For a BESS that produces revenue, how is that revenue produced? Is it expected to be sufficient to justify the cost of the BESS? Are any subsidies (for example, government) required to justify the cost?
  • For a BESS that is paired with a renewable energy source, how did that influence the cost justification? What is the typical operation of a BESS paired with a renewable energy source.
  • Finding out the typical installed cost of a BESS; for example, the cost per installed kWh ($/kWh) and per installed kW ($/kW)
  • Typical operating patterns of BESS
  • How BESS are connected to the transmission system


The PSPO group understands that some European utilities may have more experience with BESS than others throughout the world. PSPO requires that the contractor seek out these utilities to carry out the objectives of this project. However, the project is not to be limited to European utilities.
