Re: [energyinterop] Contingencies between contract offerings

[Sila Kiliccote <skiliccote@lbl.gov>]

Toby,

�

The�availability�of building side resources and their interaction with each other�should be�managed at the building controls and energy information systems. The best the the grid can hope for is the resource name, resource availability schedule (forecast) and $ value for the resource.

�

Here is how I see a building providing this information (just a simple example):

�

HE01 - No resource

.

.

HE12 - No resource

HE13 - at p =$x/kWh, B is available, at $y/kWh A&B, at $z/kWh A&C, ..., at $t/kWh E

HE14 -� at p =$x/kWh, B is available, at $y/kWh A&B, at $z/kWh A&C, ..., at $t/kWh E

.

.

HE24 - at p<= $n/kWh, F is available (F is storage)

�

There will be times of day and months or seasons in a year, that there may be no resources available or that different resources may be available.�Resource availability information�can easily be extracted from an EMCS (or perhaps a combination of EMCS and EIS).

�

While we concentrate price being presented as an absolute number, at this point, price�is�represented in many different ways (absolute or�relative (tiers, levels, etc)) and the threshold representation may change depending on the way price is represented.�

We have discussed DR responses as market offerings

We have discussed DR acquisition as contract execution, whether in advance, perhaps under a program, or at the moment the contract performance is called.

We have discussed each DR event as a call for contract performance

�

In each of these, there is the possibility that one contract excludes performance of another.

�

Simple scenario:

�

My building uses 1 MWH of electricity

I can turn off the lights for 100 kWH of DR (a)

I can provide 3 levels of lessened HVAC for 150, 350, 500 �KWH DR each. (b, c, d)

I can turn off the entire building for 1 MWH of DR (e)

�

Each of these may be priced with a different price / kWH.

�

A, B, C, D can be purchased separately.

AB, AC, and AD can be purchased as at the same time.

One cannot buy BC, BD, or CD � these responses are exclusive of each other.

If one Buys E, all other responses are off the market, even if they were already executed.

�

Each of these Offerings may have their own incompatible requirements.

�

A may only be available between Dawn and Dusk

E may require 48 hours� notice to handle tenant relations or HR Policies.

D requires 24 hours� notice to declare an �Informal Office Day�. Informal Office days need management approval.

�

B, C can be performed on 15 minutes� notice.

�

These offerings, A-E, a suite of related offerings of DR made by a single end node. For simplicity, I have limited this to shedding; it is not hard to complicate matters with DER.

�

Suggestions please, especially suggestions that map these concepts to financial or commodities markets�
