Cold storage

​

Design

​

To optimise the operation of a cold storage system by energy cost:

Once customer completes the Connect flow, or if you created their tariff via the API:

1. Identify periods when the energy cost exceeds the daily average.
2. Proactively extend temperature ahead of high cost periods and
3. Lower energy consumption during periods of higher cost periods until either the temperature reaches the maximum allowable tolerance or the cost decreases, whichever happens first.

​

To display energy cost:

1. Log consumed energy to the meter records API under the IMPORT tariff and IMPORT direction.
2. Report energy costs to customer using cost calculate API and request energy cost for IMPORT direction.

​

To display savings:

1. Log simulated consumed energy to the meter records API under the IMPORT tariff and EXPORT direction.
2. When you want to display energy saving:

• Call cost calculate API and request energy cost for IMPORT and EXPORT directions.
• Subtract IMPORT cost from EXPORT cost to get savings calculated here.
