BGE Prepares Reports for PJM
BGE uses Ventyx Retail Operations Software for Profiling and Settlement Functions
BGE uses Retail Office (RO) to prepare reports for PJM for
BGE’s 1.2 million electric accounts
– PJM’s energy market is an hourly market with hourly prices that
vary depending on system demand and weather conditions
– BGE is responsible for providing settlement reports to PJM
aggregating hourly loads for each electric customer by
electricity supplier
• Settlement A reported on a daily basis uses historical load
relationships among customer segments, weather, and timing of
hourly loads (season, day of week, hour)
• Settlement B is used to true-up Settlement A after meters are read
– Additional reports on capacity and transmission requirements
are produced daily to facilitate grid reliability
BGE’s Demand Response (DR) Reporting
Retail Office
Calculates hourly DR reductions
Calculates effects of hourly DR overrides
Creates detailed and summary reports of DR events by time period
Forecasts DR availability for the next 7 days
Support of substation-feeder specific ALM events enabling
quantification of the locational reliability and economic impact
Demand Response Eases Local Constraints
BGE’s Retail Operations Application
– Links each electric account to its feeder and substation
– Maps PeakReward devices to electric account maintaining
– Percent cycling for each device
– Timing of activation and deactivation of events
– Customer-specific over-rides of for each event
– Estimates hourly load drop during events for each event by
account, feeder, substation and for the BGE system
– Forecasts of DR availability for next 7 days
– After the fact accounting for DR events
– Supports substation or feeder specific ALM events for local
reliability and economic impact benefits
Operational Impact during Power Supply Emergencies
On July 22, 2011, PJM instituted emergency activation of
BGE’s demand response program, PeakRewards℠ for the
1st time since program’s inception
– Reduced BGE system peak demand by >600 MW
– Enabled BGE and other Maryland customers to avert
brownouts and rolling blackouts
Megawatts (MW)
BGE Load and Load Management Reductions on 7/22/11
Estimated that peak demand would have reached
7,800 to 8,000 MW.
 BGE’s 450,000 devices contributed 60% to the reduced peak demand in
BGE zone
