AI summary Table 2 presents participation data for various energy efficiency programs in 2023, including Efficient Product Rebates, Appliance Retirement, and Home Energy Assessments. The data compares actual results to the 2023 Plan as Approved and the 2023 Mid-Course Adjustment (MCA). Most programs exceeded their MCA targets, with some significantly surpassing the approved plan.
Program Components - The Residential Demand Response program component aims to help facilitate a more flexible residential load that provides residential customers with economic incentives and more visibility and control of their loads. E1...
AI summary The Residential and BNI Demand Response programs aim to enhance load flexibility through economic incentives and customer control. E1 is evaluating pathways like battery control, CPP rates, EV charging, and direct load control for residential customers, while BNI customers may see battery control, curtailment, and direct load management. These initiatives seek to improve grid efficiency and customer engagement.

Residential DR Findings and Recommendations This subsection presents the key findings and recommendations from the Residential DR evaluation. 2023 Res DR Finding: In 2023, Residential DR new available DR capacity amounted to 0.023 MW at th...
AI summary The 2023 Residential DR evaluation found that available DR capacity varied by time of day and baselining methods, with lower capacity observed in evening events and during the last hour of four-hour events. The evaluation also noted discrepancies between EOne's tracked DR capacity and the evaluator's findings, leading to recommendations for improved tracking methods.
Water Heater Controller Meter Data Analysis One of the main objectives of the 2023 evaluation was to update the baseline methodology and, as data permit, to improve the accuracy of 2022 unitary available DR capacity. To review the baseline...
AI summary The 2023 evaluation aimed to update the baseline methodology for calculating available DR capacity from water heater controllers. The Evaluator used meter data from 2022 and 2023, analyzed various baseline definitions, and developed new unitary available DR capacity for Shifted controllers. The 2020-2022 Measure Assessment was updated accordingly to reflect these changes.
3.2 Demand Response Capacity For Residential DR, savings are referred to as available DR capacity and correspond to the load reduction made available for peak demand events in participants' homes. For the DHW Direct Load Control pathway, t...
AI summary This section discusses residential demand response (DR) capacity, explaining how savings are calculated as available DR capacity through load reduction during peak demand events. It also describes the evaluation method for DHW Direct Load Control, using in-service rates and unitary available DR capacity values multiplied by the number of controllers.
5.1 BNI DR Description In 2023, EOne officially launched the BNI DR program. Since the fall 2020, EOne implemented several pilot initiatives focused on reducing demand during the Nova Scotia peak period. One of them was the DR Aggregator P...
AI summary The BNI DR program, launched in 2023 by EOne, includes a DR Aggregator Pilot pathway that recruits BNI customers to reduce load during peak periods. Aggregators like IPKeys Power Partners manage participants, who reduce demand through actions such as shutting down heating, cooling, or lighting systems. The program aimed to achieve 3.0 MW in new and total available DR capacities in 2023.
Participation in Events Through project reviews and follow-up calls with participants, the Evaluator confirmed that participants almost always participated in DR events. Only one participant mentioned not participating in an event because...
AI summary The Evaluator confirmed that participants almost always participated in DR events, with only a few exceptions due to short timelines and late recruitment.
Furthermore, the weekday when the event is called can have an impact on available DR capacity. For example, it was observed that a Monday event had considerably lower available DR capacity for one project, which was supported by the partic...
AI summary The weekday of DR events impacts available capacity, with Mondays showing lower participation due to short notice. Load profiles vary by weekday, affecting DR potential. Some events, like February 7 and 15, 2023, had significantly lower DR capacity. Limited data and adjustment factors hinder accurate modeling of daily variations.
2.5 Plug Load Controls
AI summary This section of the document focuses on plug load controls, which are measures aimed at managing and reducing energy consumption from plug-in devices in buildings.
Table 121: Domestic Water Heater Load Control Measure Summary Parameter EPI Reference Measure Description and Identification Measure Description Direct load control for domestic water heaters N/A Additional Notes - General Parameters Insta...
AI summary Table 121 provides a summary of the Domestic Water Heater Load Control Measure, including parameters such as installation rate, effective useful life, and available DR capacity. It outlines details related to energy savings and demand response capacity for direct load control on domestic water heaters.
Available DR Capacity The unitary available DR capacity for domestic water heater load controls is based on the metering data analysis results from the 2023 Residential Demand Response evaluation. During the 2021-2022 and 2022-2023 heating...
AI summary The unitary available DR capacity for domestic water heater load controls is calculated using metering data from the 2023 Residential Demand Response evaluation. Analysis showed that each unit reduced demand by an average of 385 W during the first two hours of events during the 2021-2022 and 2022-2023 heating seasons.
