[7:38] Ed Cazalet: 1. Status and comments on Transactional White Paper Draft

Transactional Energy Discussion points: Ancillary services (energy and VAR), reliability signals. vector offers, full requirements contracts.
Voting process for eMIX White Paper approval?
2. Pending confirmation from Bill, special Energy Interop/eMIX session on DR 11am PST, 2pm EST Friday
3. Use of OASIS ebCore Party ID type for Party ID in eMIX ( David Webber ?) Below is a note: from the Chair of ebcore.
"The ebCore Party ID type seems to fit their requirements both at the macro-level and the micro-level:
At the macro level, I guess most utilities are registered with the national chamber of commerce register, or have a DUNS or GS1 registration. So the B2B examples in the specification apply to them. Some utilities are looking at UBL, which we cover in the spec.
At the micro level, in many countries in Europe, every power meter has a GS1 GLN. That includes residential applications (the electricity meter in my house has a GLN).
So the ISO 6523 scheme with GS1 supports their needs, and the ebCore Party Id Type provides an off-the-shelf URI syntax for use in XML documents that want URI-valued values for Party Id type."
[8:12] Toby Considine: Exercise interval. delivery interval (3 ms)
[8:12] Toby Considine: Delivery interval - for how long you will promise to deliver
[8:13] Toby Considine: Exercise Interval - as defined in paper
[8:13] Toby Considine: VARs JR: strictly VAR - reactive energy.
[8:15] Toby Considine: Measure of Reactive Energy. Large industrial facility may have an agreement to keep power factor w/i certain ragem adjusting VAR consumers, var produced
[8:15] Toby Considine: Operator may ask you to absorb some var. Different from MW absorber
[8:17] Toby Considine: Sine wave for current, sine wave for voltage need to be lined up for max power transfer, making sure sine waves lined up. Done through Capacitors and ___, not resistors
[8:18] Toby Considine: JR: would burn off be considered transactive energy, can you put a price tag on it.
[8:19] Toby Considine: EC: Could put a price. Commodity separeate from MW called VARs. Sometimes called "Imaginary Power". Increases / decreases inductance & capacitance
[8:19] Toby Considine: If to not alligned, voltage at the end of the line drops
[8:19] Toby Considine: Often called "voltage support"
[8:20] Toby Considine: [So we need an EMIX resource type for transacting VARs in same way as megawatts.]
[8:20] Toby Considine: Volt Amp Reactive
[8:21] Toby Considine: Can operate generators in such a way as to increase or consume VARs
[8:21] Toby Considine: Some panels w/ more advanced inverters. PV can cause voltage problems in neighborhood.
[8:22] Toby Considine: Dollars per VAR-Hour, == Dollars / Megawatt Reactive Hour
[8:23] Toby Considine: EC: Over time, utilities must pay for these services, to stay w/i certain power factor.
[8:23] Toby Considine: Industrial, large commercial, not homes.
[8:23] Toby Considine: JR: Reactive power on campus, military bases, need to measure
[8:24] Toby Considine: EC: Ideally, var controls more to support entire grid.
[8:25] Toby Considine: EC: Vector offers
[8:25] Toby Considine: [more oportunity for some distributed var to support dist ennergy[
[8:26] Jeremy J. Roberts: Lines 332 through 335 in the document.
[8:43] Toby Considine: SO we have three EMIXes, one for MW, one for VAR, one for Distribution. Distribution incudes congestion fee, which may be knowable per MW, vs line losswhich is a % of energy which may have different rpices at origin. Today, the loss is often handled as make-up charge.
[8:46] Toby Considine: AH: Energy Service ID, different from Meter ID.
[8:47] Toby Considine: AH: Service ID. has charges, service charges. Meter ID not always used for billling.
[8:48] Toby Considine: MJR: Meter is a point of measurement
[8:48] Toby Considine: AH a Point of Delivery
[8:49] Toby Considine: Meter numbers may only be unique w/i a manufacturuer.
[8:49] Ed Cazalet: 16.What is an ESI ID?
Your Electric Service Identifier (ESI ID) is a unique number created by your local electric utility for your place of residence. Spark Energy uses this number to ensure that your local electric utility company places the correct service address in your name. The meter number and ESI ID number are two different things. You may have more than one ESI ID if you have several different service addresses.
[8:51] Toby Considine: TC: Mutters about n-to-n relationships between ESI , Meters, and ESI IDs
[8:54] Toby Considine: AH: A lot of these things have been done in black boxes
