On 20th September 2016, the Australian Energy Market Operator (AEMO) provided this 7 page submission to the COAG consultation process asking about both:
1) The need for a central register of installed battery storage facilities; and
2) A process by which it might be developed and maintained.
In its submission, AEMO references the work (documented here on their website) that they are doing in the “Future Power System Security” (FPSS) project. That page of their website links to an AEMO presentation providing one forecast for how quickly battery storage might be deployed. That presentation lists the four high priority areas that the AEMO sees they need to address in this energy transition:
The AEMO’s interest in this Energy Storage Register falls into the 3rd priority area – which they have titled “Information, data and models”. Understanding more about what’s been deployed in terms of battery storage, and associated technology (particularly the inverter) is one of the data sets of interest to AEMO.
In its submission to the COAG Consultation, AEMO notes the need for a truly national focus (i.e. beyond the NEM – including the SWIS and other locations as well), given that the data requirements will be just as pertinent elsewhere.
In our summary page here we proposed 4 key reasons why an Energy Storage Register could be required:
|Reason 1 = To assist First Responders||
It is understandable that the AEMO submission does not comment on this need.
Where they are provided, we link to other articles referencing assistance to first responders as a reason for the Energy Storage Register.
|Reason 2 = To assist in any potential future product recalls||It is understandable that the AEMO submission does not comment on this need.
Where they are provided, we link to other articles referencing potential future product recalls as a reason for the Energy Storage Register.
|Reason 3 = To assist with life-cycle management||It is understandable that the AEMO submission does not comment on this need.
Where they are provided, we link to other articles referencing life-cycle management as a reason for the Energy Storage Register.
|Reason 4 = To assist with electricity system operations and planning.||Given that electricity systems operations and planning is AEMO’s responsibility, it is understandable that AEMO focuses here. In their submission (p2) they highlight 3 areas of concern with respect to data for distributed energy facilities:
Concern #1 – with respect to “forecasting in various future timeframes…” (refer the submission for more)
Concern #2 – with respect to “technical operating limits of the power system …”
Concern #3 – with respect to “under-frequency load shedding schemes…”
In particular, they flag the (assumed) “undiversified operation of DER” as a new parameter that represents a change from the historical nature of diversified human behaviour.
We recommend that interested parties review the full AEMO submission to understand more of their perspectives.
Where they are provided, we link to other articles referencing electricity system operations and planning intelligence as a reason for the Energy Storage Register.
The AEMO (p5) suggests various aspects to be considered (Adaptability, Technology neutrality, Accessibility (with security), Efficiency, National application, Co-ordination and Compliance) in the development of the Energy Storage Register.
In our process of building this Energy Storage Register, we have reviewed this material, and have already held numerous conversations with various people in the AEMO. We will continue to do so in the months ahead as the project progresses – in order that we can best serve the AEMO, as a potential customer for the Energy Storage Register.
