RTP Customers Optimization

The RTP system provides the RTP schedule through email, pager, bulletin board or direct transfer. The RTP operator at for the customer must enter the schedule into the building automation software (BAS) and perform the necessary optimization activities to implement the RTP goals. Note that EMS or Energy Management System is often used interchangeably with BAS.

The Energy Services Provider (Energy Service Provider) obtains the Base RTP data tables from the Market Interface Server, and uses them to develop Customer-specific RTP rate tables. These calculations are based on contractual agreements between the Energy Service Provider and the different types of customers it serves. For example, a large industrial customer that can curtail large loads during peak hours will get a different rate than a small commercial customer with less ability to modify its load. The Energy Service Provider sends these Customer-specific RTP rate tables to each of the customers it serves, using different mechanisms: fax, email, or direct data channels (e.g. dial-up telephone or AMR system).

The customer’s Building Automation System (BAS) optimizes its loads and distributed energy resources (DER), based on the customer-specific rate table it receives, the load requirements and constraints, and any DER requirements, capabilities, and constraints. The BAS understands the nature and opportunity for altering consumption based on economic and comfort drivers, and, the physical dynamics of the specific customer premises. The BAS then issues (or updates existing) schedules and other control mechanisms for loads and for DER generation. These control actions may be automatically implemented or may be reviewed and changed by the customer. The Customer’s BAS may then send generation schedules to the DER management system for it to implement during each “settlement” period. Note that the BAS may be a human as apposed to a software system.

The BAS system uses the site-optimized algorithms to forecast its load and DER generation. It also determines what additional ancillary services it could offer, such as increased DER generation or emergency load reduction, and calculates what bid prices to offer these ancillary services at. The BAS then submits these energy schedules and ancillary services bids to the Energy Service Provider (or Scheduling Coordinator, depending upon market structure), as input to the RTO/ISO market operations.

#	Event	Name of Process/Activity	Description of Process/Activity	Information Producer	Information Receiver	Name of Info Exchanged	IntelliGrid Architecture Environments
1.1	Timer or Notification of new rates available	Customer processes RTP schedule	The customer receives and processes the RPT schedule for the next period. This could be by accessing a web page or reading email.	Energy Service Provider	Customer	RTP rates	ESP to Customer
1.2	Receipt of new rates	Customer Enters data into BAS	The customer enters the RTP schedule for the next period into the BAS.	Customer	Customer Building Automation System	RTP rates	Intra-Customer Site
1.3A.1	Entry of new rates	Load Optimizations based on RTP	Customer Building Automation System optimizes projected loads, deferrable load and DER based on requirements, constraints and RTP rates.	Customer Building Automation System	Customer	Load deferment and DER schedules	Intra-Customer Site
1.3A.2	BAS optimizations complete	Customer Review of BAS optimizations	Customer reviews the load schedule and approves based on external criteria	Customer	Customer	Load deferment and DER schedules	Intra-Customer Site
1.3A.3	Load deferment and DER schedules approved	Implement Load and DER schedules	The customer now implements the approved load and der schedules either manually or enabling the schedule in the BAS.	Customer		Load deferment and DER schedules	Intra-Customer Site
1.3B.1		Energy / ancillary services bids	Customer BAS evaluates bids into energy and ancillary services.	Customer Building Automation System	Customer	Energy / ancillary services bids	Intra-Customer Site
1.3B.2	BAS optimizations complete	Customer review of energy and ancillary services bids	Customer reviews the proposed bids into energy and ancillary services markets, verifying availability and bid data.	Customer	Customer	Energy / ancillary services bids	Intra-Customer Site
1.3B.3	Review of energy and ancillary services bid	Transmit Bids to Energy Service Provider	Customer, having approved the energy and or ancillary bids, transmits those bids to the Energy Service Provider or market operator	Customer	Energy Service Provider	Energy / ancillary services bids	ESP to Customer
