GridBanks are scalable energy reservoirs that store and deliver grid-scale electricity on demand.

• 1 MWh of energy / 2 MW power continuously • Peak power capabilities of 4 MW • No risk of fire or explosion• High efficiency / Low internal resistance • Low cooling needs / Air cooled • The standard configuration is coupled to 2 MW

inverter (inverter primary supplier is Parker Hannifin.)

Order 755, “Frequency Regulation Compensation in the Organized

Wholesale Power Market,” requires regional transmission organizations

(RTOs) and independent system operators (ISOs) to adopt a two-part

market-based compensation method for frequency regulation services

• A capacity payment reflecting opportunity costs

• A market-based performance payment

(This payment rewards faster-ramping resources)

Studies run by DNV KEMA illustrated that fast ramping resources have a

3X effectiveness in providing regulation services

• The graph to the right illustrates the ability of fast ramping

resources (bottom right) to follow AGC (Automated Generator

Control – 2s signal) while a slow ramping generator unit is

unable to accurately follow the ramp signal (top right).

• Maximum deadband +0.1Hz • full output in 1s from the

detection of a frequency deviation.

• availability performance of greater than 95%

• minimum sustained delivery duration of 9 seconds

• AEMO’s initial modelling of the impact of battery storage, electric vehicles and fuel switching in the 20-year NEFR outlook period.

• Modelling battery storage: no mechanism for tracking the number of installations in Australia.

• AEMO has developed the first step of its economic model to estimate the uptake of battery storage systems by residential consumers
