Modify Energy Plans structure to allow Time of Use based Controlled Load rates #472

CDR-API-Stream · 2022-02-14T06:47:43Z

Description

Controlled Load rates can be fixed or based on time of use (e.g. different controlled load rates for peak vs off-peak). This change request is being created to modify the structure to cater for Controlled load Time of Use rates as current controlledLoad object does not cater it.

Area Affected

Following Energy APIs are affected

Change Proposed

The following change is proposed to the controlledLoad object to cater for TOU based controlled load rates:

{
    "controlledLoad": {
        "displayName": "string",
        "rateBlockUType": "[ singleRate | timeOfUseRates ]",  //Attribute to specify rate type
        "singleRate": {
            "displayName": "string",
            "description": "string",
            "dailySupplyCharge": "string",
            "period": "string",
            "rates": [
                {
                    "unitPrice": "string",
                    "measureUnit": "[ KWH | KVA | KVAR| KVARH | KW | DAYS | METER | MONTH ]",
                    "volume": 0
                }
            ]
        },

            {
                "displayName": "string",
                "description": "string",
                "dailySupplyCharge": "string",
                "rates": [
                    {
                        "unitPrice": "string",
                        "measureUnit": "[ KWH | KVA | KVAR| KVARH | KW | DAYS | METER | MONTH ]",
                        "volume": 0
                    }
                ],
                "timeOfUse": [
                    {

                        "endTime": "string"
                    }
                ],
                "type": "[ PEAK | OFF_PEAK | SHOULDER ]"
            }
        ]
    }
}

Please find below the response on proposed structure.

Add Start Date (MM-DD) and End Date (MM-DD) (similar to EnergyPlanTariffPeriod) to support seasonal rates for Controlled Load.
Proposed Days for controlled load section is aligned with EnergyPlanTariffPeriod > timeOfUseRates section. Can we please also align Demand Section Days similar to this proposed enumerated value so that days representation are unique across. This would also allow specifying demand is applicable for Business days (currently allows weekdays and weekend options only).

Thanks,
Kingson

Kingson-EA · 2022-03-23T23:47:05Z

If a site has two separate controlled load meter, there can be two different controlled load rates. As this controlled load section is not an array, we can specify only one controlled load rate. Can you please assess the proposed structure to allow us specifying rate for more than one controlled load (i.e Controlled Load 1 & Controlled Load 2).

Thanks,
Kingson

@Kingson-EA thank you for your feedback.

Add Start Date (MM-DD) and End Date (MM-DD) (similar to EnergyPlanTariffPeriod) to support seasonal rates for Controlled Load.

We can include the start and end date as optional attributes.

Proposed Days for controlled load section is aligned with EnergyPlanTariffPeriod > timeOfUseRates section. Can we please also align Demand Section Days similar to this proposed enumerated value so that days representation are unique across. This would also allow specifying demand is applicable for Business days (currently allows weekdays and weekend options only).

As mentioned in the previous MI call, we will raise a separate CR to consult for consistent representation of ENUM values for 'days' across sectors and within energy endpoints

If a site has two separate controlled load meter, there can be two different controlled load rates. As this controlled load section is not an array, we can specify only one controlled load rate. Can you please assess the proposed structure to allow us specifying rate for more than one controlled load (i.e Controlled Load 1 & Controlled Load 2).

This is good feedback. Is it also worth considering including an optional meterId attribute to specify which meter the controlled load rates apply to? Alternatively, the meter information can be captured in a description attribute.

perlboy · 2022-04-13T07:13:38Z

This proposal seeks to force the adoption of a non-standard time format beyond the "existing data sources" and inherits a lack of precision in the process.

A number of justifications for this were given from the call:

Another payload "at the same level" is using HHMM tariffPeriod. The same could be said about solarFeedInTariff which actually uses TimeString for a very similar requirement named literally the same way as the proposal.
Expansion of an existing payload. The specific timeOfUse attribute in EnergyPlanTariffPeriod is an anonymous schema (ie. it isn't a named schema) which, from an implementers perspective, means the "existing payload" statement is technically incorrect.
Implementation cost. This didn't seem to involve consulting actual implementers and, in the case of AER related API deliverables seem to relate specifically to AER implementation cost to implement a fairly generic transform. In fact, the desire to keep HHMM seems to have led to an acceptance of a non-international format to avoid, literally, a one liner being used by the delivery personnel of Get Generic Plan. Since the DSB are such fans of Ruby that's time = Time.new; time.strftime("%k%M") by the way. Conversely using the TimeString format is just as easily parsed if desired to the magical format, while having the precision of its original data source dropped by choice.
The retailers already supply to AER in this format. This isn't technically true for this proposal because the proposed data isn't in the AER data now. Nonetheless, if we look at this more broadly, at least 2 energy retailers (and indeed any retailer using a pretty popular energy billing platform, ie. 100s) it is happening as a transformed extract from a data source which is already handling it in a well defined time format (specifically GraphQL timetz). Implementers are highly unlikely to reparse AER extracts for the EnergyAccountDetail instead retrieving it from the source is both architecturally and implementation cost wise preferred.

Further AER doesn't supply this specific addition (ie. it isn't existing data), the parsing of this value requires not only industry specific knowledge (eg. is this UTC? Is it location based? How does one actually use it) but also the specification of the data format and specification supplied to AER by retailers doesn't seem to be easily accessible (where is it actually published? Does someone know?).

As per the call, my opinion (and the general opinion of Biza.io and possibly any sane engineer who has ever had to do time math) would be to align, wherever possible, with CDR Data Types. These Data Types were specifically defined, hard fought, in many cases to the chagrin of purists who said "Use Native Types" (Me included). Not defaulting to these in essence diminishes the value produced by being divergent from natives in the first place and instead creates an implied EnergyTimeString for JSON serialisers that will come with whatever the cascading effects involving added then removed timezones back and forth as they make their way through the web of transforms.

The only reasonable justification to do otherwise seems to be a like for like transform from an existing data source - this has tacit acceptance although no defined Standards principle (literally nothing in the principles explicitly supports this pathway). More broadly speaking this justification should be assessed as, with multiple industries in multiple formats, the implementation of defining endlessly variant ways of time, dates, decimals, currencies etc. with variable levels of precision introduces a significant technical debt problem for implementers of CDR itself and will inevitably result in transformation issues between participants.

Finally, on Principles, here's a list that seems to not be aligned:

Outcome Principle 2: APIs use open standards. In order to promote widespread adoption, open standards that are robust and widely used in the industry will be used wherever possible.
Outcome Principle 4: APIs provide a good developer experience. To ensure that the entry hurdle for new developers is low the experience of the developers that are building clients using the APIs will be considered. The ability for a developer to easily understand and write code using the APIs in modern development environments should be facilitated by the API standards.
Outcome Principle 5: Standards are consistent across sectors. The standards will strive for consistency in patterns, structure, security mechanisms and user experience across sectors to facilitate the development of customer experiences and services that are able to integrate data from multiple sectors seamlessly and to reduce the cost of customer education for new sectors.
Technical Principle 3: APIs are simple. As complexity will increase implementation costs for both holders and clients as well as reduce the utility of the APIs, API definitions should seek to be as simple as possible but no simpler.
Technical Principle 6: APIs are consistent: The API definitions across the full suite of APIs should be consistent with each other as much as possible. Where possible common data structures and patterns should be defined and reused.

Thank you for the feedback @perlboy.

There a couple of points worth reiterating/clarifying:

The proposed timeofuse structure for controlled load is derived directly from tariffPeriod as it provides more flexibility and leverages a pattern already in place within this payload.
AER does hold information about time of use based controlled loads with rates and is expected to provide them. Some examples below:

Uplifting time of use to be better while still being consistent across the payloads is an important discussion. As a result, and as mentioned during the MI call, the DSB will raise a CR to consult separately on how time is represented within EnergyPlanSchema. ~~This comment will be updated with the link to the CR once raised.~~ New issue #505 has been raised.

For this CR, however, we believe that the current proposed solution is more appropriate and will be recommending this to Chair for incorporation into 1.17.0.

Ok then I misunderstood what was stated on the call. This would suggest the original payloads did not provide coverage for the AER data to begin with.

Since it is apparent the Generic Plans APIs may be deficient for presentation of existing AER data it's worthwhile evaluating the examples more deeply.

Some examples below:

https://www.energymadeeasy.gov.au/plan?id=SIM313052MRD1&postcode=5000

This plan includes a controlled load tariff of "Controlled Load - Solar Sponge" which doesn't seem to specify PEAK, OFF_PEAK, SHOULDER. How would this be presented in the proposed structure?

https://www.energymadeeasy.gov.au/plan?id=SIM244354MRD1&postcode=5000

This plan includes a controlled load tariff of "Controlled Load - Solar Sponge" which doesn't seem to specify PEAK, OFF_PEAK, SHOULDER. How would this be presented in the proposed structure?

https://www.energymadeeasy.gov.au/plan?id=RED66349SBE2&postcode=2000

This plan describes a Controlled Load charge that is "Generally available for a 6 hours period between 10pm and 7am.". How is the 6 hour limit described in the proposed structure?

https://www.energymadeeasy.gov.au/plan?id=RED207686MRE4&postcode=2500

This plan describes a Controlled Load charge that is "Generally available for limited hours between 10pm and 7am" and another described as "Generally available for restricted periods not exceeding 17 hours". How is this described in the proposed structure?
This plan describes a Solar Feed-in Tariff for the first 5kWh then another for the remainder. This doesn't appear to be supported in the existing payloads?

Uplifting time of use to be better while still being consistent across the payloads is an important discussion. As a result, and as mentioned during the MI call, the DSB will raise a CR to consult separately on how time is represented within EnergyPlanSchema. This comment will be updated with the link to the CR once raised.

Great.

For this CR, however, we believe that the current proposed solution is more appropriate and will be recommending this to Chair for incorporation into 1.17.0.

Sure although the proposed solution doesn't seem to cover all the use cases....

CDR-API-Stream · 2022-04-22T05:23:05Z

Given the feedback from @perlboy, we suggest the following two options to progress this CR:

Option 1 - Resolve this CR in current MI10 incorporating the solution recommended as per this comment in v1.17.0 of the standards. This could give a baseline to anyone already implementing this specific component. The baseline can be further refined (e.g. include more ENUM values) with separate CRs in future MIs to cater for any remaining use cases.

Option 2 - Carry over and resolve this CR in the next MI (which starts next week on 27th April) to discuss and address the above feedback.

Any feedback on the above two options would be appreciated. We can table this as part of the grooming session at the start of MI11.

So, I went digging into EME and there seems to be quite a few more things worth investigating. These are noteworthy particularly in the context of "existing data sources" but also in the handling of time, dates, days and currency for Energy endpoints. I've provided links to the individual JSONs used for this info. These all matter because beyond AER data Retailers are now expected to present contract data in response to Energy Account Details. Maybe this is the feeder for other items but I'll put it here for now because it does relate to the original change request on time of use tariffs and matching those to AER data.

startTime and endTime values from AER are in the format [H]HMM not HHMM . If this is the case then the Standards seem to be redefining the existing data to be zero padded. This is important because neither format is an RFC standard so parsers will be written to process it, it is a string so it is a transform during serialisation and timezone data appears to be inconsistent (see below)
Prices appear to be stored as cents (eg. 38.09 for $0.3809). If this is the case then the Standards are requiring a transform of this to an AmountString which is 0.3809 but validating this will be challenging because AmountString is unbounded (ie. 38.09 is a valid value).
In the JSON payloads capitalisation is variable between enums. Sometimes it is BUSINESS DAYS and other times it is Business Days. OpenAPI schema is case sensitive so I presume these will be uppercased and transformed.
Business Days enumeration seems to be a synonym for Monday->Friday regardless of public holidays. This would suggest the inclusion BUSINESS_DAYS value in the day definition enum is actually unnecessary and in fact ambiguous. The enum therefore could be normalised to actual days of the week at which point recycling banking lastWeekDay enum would be more consistent (ie. three letter days) with the Standards
- Not once did I find a plan which actually defined specific days or public holidays. Maybe I didn't look hard enough, maybe it's a C&I thing, not sure but the overwhelmingly common situation for days in EME data seemed to be Business Days|Saturday|Sunday which seems to actually mean, and indeed is presented on EME as, 7 days per week regardless of public holidays.
Timezones appear to be getting defined in descriptions but AER data has something too. RED66349SBE2 for example is defined as AEST in the description but provided as LOCAL in the timeDefinition. This is relevant because it goes to the use of HHMM rather than a timezone qualified CDR TimeString and the fact that, at a minimum, there isn't any time definition field. LOCAL is a commonly used timeDefinition which I guess means "Local Time" but there seems to be situations where this conflicts non-AE[D]ST locations.
Retailers seem to provide a lot of energy plans which are duplicated across postcodes - maybe this is an AER/EME transform outcome. Nonetheless, the EME site filters based on postcode so it would seem Get Generic Plans would benefit from a filter for postcode especially since EnergyPlan already includes/excludes postcodes

By way of examples, here is some info from the sources provided below:

The definition of days seems ambiguous, this will make calculations wrong (tariffPeriod.touBlock) :
1. The following plans have all of tariffs defined as Business Days, Saturday & Sunday. Public Holidays aren't defined:
  1. SIM244354MRD1
  2. SIM313052MRD1
  3. DEN254925SRE1
2. The following plans have all of tariffs defined as Business Days, Saturday & Sunday. Public Holidays aren't defined and description says Monday to Friday:
  1. RED207686MRE4
  2. RED66349SBE2
The definition of Shoulder seems very variable, this will make use of this data difficult but I guess it is a commercial decision by retailers:
1. SIM244354MRD1 & SIM244354MRD1 Solar Sponge is a Shoulder type between 10am -> 3pm Business Days, Saturday, Sunday
2. RED207686MRE4 & RED66349SBE2 Shoulder is defined as 7am->1pm and 8pm->10pm Monday to Friday (or Business Days depending on if you're reading description or payload) and 7am-10pm on Weekends.
3. DEN254925SRE1 Shoulder is defined as 7am -> 2pm and 8pm -> 10pm Business Days, Saturday, Sunday
Start Date & End Dates appear to be broken or EME has defaults. It matters because endDate is Mandatory in the Standards:
1. The following plans have expired tariffs that started 2021-01-01 and finished 2021-12-31:
  1. SIM244354MRD1
  2. SIM313052MRD1
2. The following plans have tariffs that started 2020-07-01 and finished 2020-06-30 (yes, they finish before they start):
  1. RED207686MRE4
  2. RED66349SBE2
  3. ORI208128MRE6
  4. AGL15222MRE14
3. The following plans have tariffs starting 2021-07-01 and finishing 2022-06-25:
  1. DEN254925SRE1
  2. ENE19179MRE27
Time Definitions appear to be variable:
1. The following plans define timeDefinition as AEST:
  1. SIM244354MRD1
  2. SIM313052MRD1
  3. RED207686MRE4 but the terms text states "All times are AEST, unless you have an interval meter, in which case daylight savings time will apply."
2. The following plans define timeDefinition as LOCAL:
  1. ORI208128MRE6
  2. AGL15222MRE14
  3. ENE19179MRE27
3. RED66349SBE2 uses LOCAL but the description the consumer sees is AEST. This is important because it is for 2000 postcode which has daylight savings
4. DEN254925SRE1 defines it as AEST which is interesting because it is offered in an ACST timezone (ie. Adelaide) and the shoulder periods seem to be aligned with local time

The EME team in collaboration with the DSB provided the initial design for the ToU Controlled Load proposal, however, @perlboy has quite rightly highlighted the need for further consultation on this design to ensure that retailer products can be adequately represented by the Standards.

Acknowledging @perlboy's investigative efforts into the EME API, it's worth noting that this endpoint is specifically designed to service the EME UI, only exposes a limited amount of data for that purpose, and that this data should in no way be interpreted as the AER's CDR PRD. The AER is building CDR PRD endpoints that will expose EME and Victorian Energy Compare (VEC) product data transformed to conform with the Standards.

Some of @perlboy's insights from his investigation do warrant further discussion, but not here. I will tackle them in separate proposals.

Thanks Joe and totally agree. To clarify our primary interest in this analysis actually relates to the Account Detail components that reuse the Product Data payloads in those payloads primarily because there is a data transform component related to things like "Business Days" (which week by week is challenging).

As per a previous reply:

Further AER [....] but also the specification of the data format and specification supplied to AER by retailers doesn't seem to be easily accessible (where is it actually published? Does someone know?).

I would have preferred to use the input format supplied by retailers to AER when analysing this but it didn't seem to be available - is that something you could provide a link to?

joe-aer · 2022-05-12T01:30:03Z

Unfortunately Stuart, the EME data specification document is only available to authorised energy retailers.

perlboy · 2022-05-12T04:56:31Z

Unfortunately Stuart, the EME data specification document is only available to authorised energy retailers.

That's interesting because I would have thought as a Government agency unless there was some national security or confidentiality requirement such a document would be in the public interest especially since the justification for adoption of certain data types within the Standards is on the basis of existing data formats.

CDR-API-Stream · 2022-05-25T07:04:03Z

Below points summarise the above feedback that was discussed in today's MI11 call:

The proposed time of use type for controlled load does not currently cater for Solar Sponge:
- This can be addressed by add "SOLAR_SPONGE" to the list of type ENUM values.
- Feedback is welcome on any other values that would need to be included
Controlled loads that have non-specific time of use description such as "Generally available for a 6 hours period between 10pm and 7am."
- Feedback from AEMO stated that such scenarios imply the retailers are not aware of the specific time of controlled load application as this is determined by the distributor. The time can vary daily within defined bounds. In the above example a consumer would get 6 hours of controlled load usage anytime between 10pm and 7am.
- The DSB will consider on how to represent this in the standards
- Further feedback from other retailers is welcome.
Stepped solar feed in tariffs
- Stepped charges that are applied based on fixed usage/export amount (e.g. x cents for first 5kWh/day, y cents for the remainder)
- Example - https://www.energymadeeasy.gov.au/plan?id=RED207686MRE4&postcode=2500)
- A separate CR will be raised to consult on this issue
Standardised representation time in EnergyPlanDetail schema and alignment of ENUM value for days across energy standards
- Both of these issues have been raised as separate CRs (linked below), both will be included in MI11 for consultation
- CR for time representation
- CR for standardising ENUM values for days in energy standards

CDR-API-Stream · 2022-06-01T11:44:31Z

The DSB would like to propose the following changes to address point 1 and 2 in the above comment:

Add "SOLAR_SPONGE" to type ENUM list
Make the following attributes within timeOfUse array optional
- days - NOTE: The ENUM values will be aligned to agreed decision in Review ENUM values for representation of days in Energy Standards #502
- startTime - NOTE: The type of this attribute will be aligned to agreed decision in Representation of time within EnergyPlanDetail Schema #505
- endTime - NOTE: The type of this attribute will be aligned to agreed decision in Representation of time within EnergyPlanDetail Schema #505
Add the following optional attributes to timeOfUse array
- additionalInfo - Optional free text attribute to provide description about controlled load availability if specific day/time is not known
- additionalInfoUri - Optional attribute to provide link to web page with additional information

The combination of change 2 and 3 should allow specifying controlled load plans where details of time of use are not known and contain description such as:

Generally available for limited hours between 10pm and 7am
Generally available for restricted periods not exceeding 17 hours
Generally available for a 6 hours period between 10pm and 7am

Below is the revised controlloedLoad schema:

{
    "controlledLoad": [ //controlledLoad is an array
            {
            "displayName": "string",
            "rateBlockUType": ["singleRate","timeOfUseRates"], //Attribute to specify rate type
            "startDate": "DateString", //optional
            "endDate": "DateString", //optional
            "singleRate": {
                "displayName": "string",
                "description": "string",
                "dailySupplyCharge": "AmountString",
                "period": "string", //Formatted according to ISO 8601 Durations (excludes recurrence syntax)
                "rates": [
                    {
                        "unitPrice": "AmountString",
                        "measureUnit": ["KWH", "KVA", "KVAR", "KVARH", "KW", "DAYS", "METER", "MONTH" ],
                        "volume": "number"
                    }
                ]
            },
            "timeOfUseRates": [ //Object to capture Time of Use based Controlled Load rates
                {
                    "displayName": "string",
                    "description": "string",
                    "dailySupplyCharge": "AmountString",
                    "rates": [
                        {
                            "unitPrice": "AmountString",
                            "measureUnit": ["KWH", "KVA", "KVAR", "KVARH", "KW", "DAYS", "METER", "MONTH" ],
                            "volume": "number"
                        }
                    ],
                    "timeOfUse": [
                        {
                            "days": ["SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY", "BUSINESS_DAYS"], //Make attribute optional. NOTE: The ENUM values will be aligned to agreed decision in CR 502
                            "startTime": "string", //Make attribute optional. NOTE: The type of this attribute will be aligned to agreed decision in CR 505 
                            "endTime": "string", //Make attribute optional. NOTE: The type of this attribute will be aligned to agreed decision in CR 505
                            "additionalInfo" : "string", //Optional free text attribute to describe controlled load availability if specific day/time is not known
                            "additionalInfoUri" : "string" //Optional attribute to provide link to web page with additional information 
                        }
                    ],
                    "type": [ "PEAK | OFF_PEAK | SHOULDER | SOLAR_SPONGE" ] // added SOLAR_SPONGE
                }
            ]
        }
    ]
}

Feedback is welcome on the above recommended changes.

Following feedback received during Energy MI call on 14th June, the DSB discussed the structure internally and notes that the period field in singleRate structure does not apply anymore. The timeOfUseRates structure in the proposed controlloedLoad schema can be used to describe different rate periods. As a result, the DSB recommends removing it.

Below is the updated structure:

{
    "controlledLoad": [ //controlledLoad is an array
            {
            "displayName": "string",
            "rateBlockUType": ["singleRate","timeOfUseRates"], //Attribute to specify rate type
            "startDate": "DateString", //optional
            "endDate": "DateString", //optional
            "singleRate": {
                "displayName": "string",
                "description": "string",
                "dailySupplyCharge": "AmountString",
                "rates": [
                    {
                        "unitPrice": "AmountString",
                        "measureUnit": ["KWH", "KVA", "KVAR", "KVARH", "KW", "DAYS", "METER", "MONTH" ],
                        "volume": "number"
                    }
                ]
            },
            "timeOfUseRates": [ //Object to capture Time of Use based Controlled Load rates
                {
                    "displayName": "string",
                    "description": "string",
                    "dailySupplyCharge": "AmountString",
                    "rates": [
                        {
                            "unitPrice": "AmountString",
                            "measureUnit": ["KWH", "KVA", "KVAR", "KVARH", "KW", "DAYS", "METER", "MONTH" ],
                            "volume": "number"
                        }
                    ],
                    "timeOfUse": [
                        {
                            "days": ["SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY", "BUSINESS_DAYS"], //Make attribute optional. NOTE: The ENUM values will be aligned to agreed decision in CR 502
                            "startTime": "string", //Make attribute optional. NOTE: The type of this attribute will be aligned to agreed decision in CR 505 
                            "endTime": "string", //Make attribute optional. NOTE: The type of this attribute will be aligned to agreed decision in CR 505
                            "additionalInfo" : "string", //Optional free text attribute to describe controlled load availability if specific day/time is not known
                            "additionalInfoUri" : "string" //Optional attribute to provide link to web page with additional information 
                        }
                    ],
                    "type": [ "PEAK | OFF_PEAK | SHOULDER | SOLAR_SPONGE" ] // added SOLAR_SPONGE
                }
            ]
        }
    ]
}

If no further feedback is received, the DSB will recommend the above change to the Chair for approval.

Note: The ENUM values of days field will be aligned to agreed decision in #502
and attribute type of startTime and endTime will be aligned to agreed decision in #505
