Schedule 4—Energy storage system—component guidelines

(see subpar 80(4)(a)(i) of the Act)

 1.1 Components are considered part of a facility if they are integral to the operation of the system, and the drawing in of electricity, storage of energy, or dispatch of electricity regardless of the owner or operator of the components.

 1.2 Infrastructure including buildings or stationary infrastructure are included.

 1.3 The components of a facility may vary depending on the type of facility.

 1.4 This schedules is not intended to limit the components of an energy storage system that may be taken to be part of a facility for the Act.

 1.5 Generally, energy storage systems are likely to include the following components:

 (a) switchboard or switchroom;

 (b) transformer;

 (c) control system;

 (d) telemetering system;

 (e) protection system;

 (f) metering instrument;

 (g) monitoring instrument;

 (h) instrumentation;

 (i) buildings or stationary infrastructure;

 (j) backup power supply;

 (k) cabling;

 (l) switchyard.

2  Battery Energy Storage System

 2.1 For a facility that is a battery energy storage system, the components may also include the following:

 (a) battery modules (consisting of battery cells);

 (b) framework and housing;

 (c) power conversion system (inverter, converter);

 (d) thermal management system;

 (e) fire suppression system.

3  Compressed Gas Energy Storage System

 3.1 For a facility that is a compressed gas (e.g. air or CO2) energy storage system, the components may also include the following:

 (a) motor;

 (b) generator;

 (c) turbine;

 (d) compressor;

 (e) expander;

 (f) storage system (could be a tank or cavern);

 (g) condenser (intercooler/aftercooler);

 (h) recuperator;

 (i) cooling system;

 (j) piping and fittings.

4  Thermal Energy Storage System

 4.1 For a facility that is a thermal energy storage system, the components may also include the following:

 (a) turbine;

 (b) motor;

 (c) generator;

 (d) storage medium;

 (e) heating equipment (heater, preheater, reheater);

 (f) heat exchanger;
