J-1Notice of Appeal (redacted) 5 passages
How do they want the complaint resolved?
How do they want the complaint resolved? I would like an investigation into how a power bill can go from $100/month to $400 a month. NS Power has attributed the increase to the installation of an energy efficient ducted heat pump in April...

AI summary The complainant is requesting an investigation into a sudden increase in their power bill from $100/month to $400/month, which NS Power attributes to the installation of an energy-efficient ducted heat pump in April 2025. The complainant has sought a written decision from the DRO and is concerned about potentially missing the 12-day appeal window.

NS Power's meter records show:
NS Power's meter records show: Period Actual usage Days Approx. kWh/day Nov. 22, 2024 – Jan. 24, 2025 3,058 kWh 63 48.5 Jan. 24 – Mar. 24, 2025 2,660 kWh 59 45.1 Mar. 24 – Sept. 19, 2025 5,687 kWh 179 31.8 Sept. 19 – Nov. 19, 2025 2,363 kW...

AI summary NS Power's meter records show significant variations in energy usage across different periods, with a particularly notable increase during winter months, such as from Nov. 19, 2025 – Jan. 23, 2026, where daily usage reached 81.9 kWh.

Preamble
Nov. 2024–Mar. 2025: approximately 45–49 kWh/day compared with Nov. 2025–Mar. 2026: approximately 82–102 kWh/day. That is roughly double the previous daily consumption during those two winter billing periods. I understand that my ducted he...

AI summary The customer reports a significant increase in electricity consumption, from 45–49 kWh/day in Nov. 2024–Mar. 2025 to 82–102 kWh/day in Nov. 2025–Mar. 2026, attributing it to the installation of a ducted heat pump. They question whether this increase is reasonable given the replacement of oil heating.

2. The EnerGuide assessments raise a legitimate question about the magnitude of the increase
2. The EnerGuide assessments raise a legitimate question about the magnitude of the increase My December 2024 EnerGuide assessment, before the heat pump, estimated: - Total annual energy consumption: 154 GJ - Oil: 111 GJ - Electricity: 43...

AI summary The EnerGuide assessments show a significant reduction in total energy consumption after installing a heat pump, but a notable increase in electricity consumption. The author requests the Board to examine the magnitude of these changes, as they may not be solely attributable to the heat pump installation.

What I am asking the Board to review
What I am asking the Board to review I am respectfully asking the Board to independently review: - 1. Whether the actual meter readings and resulting consumption calculations are correct; - 2. The significant increase from approximately 45...

AI summary The applicant, Stephanie Jamieson, is requesting the Board to review the accuracy of meter readings, the increase in electricity consumption after installing a heat pump, the heat pump's impact on consumption, the effect of missed Equal Billing reviews during a cybersecurity incident, and whether the resulting balance and payment amount should be reconsidered.

J-2Energy Assessment EnerGuide Rating Jan 2025 (redacted) 1 passage
Section 1
The energy consumption indicated on your utility bills may be higher or lower than your EnerGuide rating. This is because standard assumptions have been made regarding how many people live in your house and how the home is operated. Your r...

AI summary The energy consumption on utility bills may differ from EnerGuide ratings due to standard assumptions about household size and home operation. The rating is based on the house's condition during evaluation. Quality assured by Trinity Energy Group.

J-3Energy Assessment EnerGuide Sheet May 2025 (redacted) 1 passage
Section 1
The energy consumption indicated on your utility bills may be higher or lower than your EnerGuide rating. This is because standard assumptions have been made regarding how many people live in your house and how the home is operated. Your r...

AI summary The text explains that utility bills may show energy consumption different from the EnerGuide rating due to assumptions about household size and home operation. The EnerGuide rating is based on the house's condition at the time of evaluation.

Don Farmer, P. Eng,,..llliputc Resolution Officer (D,R.O,)
Your Dispute in summarx..ls: that you have service from N .S.Power at ; that you are disputing your 2 July 2026 outstanding balance of $3829.77 (ledger attached); that you are a single Mom of two; thatnyou have been on Equal billing of$100...

AI summary The customer is disputing an outstanding balance with Nova Scotia Power, citing financial hardship as a single mother of two. The dispute includes concerns over billing accuracy following a cybersecurity incident, estimated billing, and the impact of a heat pump on electricity consumption. The customer questions the magnitude of the increase in electricity consumption and whether it is reasonably explained.

Before the heat pump - December 2024
Before the heat pump - December 2024 • Rated annual energy consumption: 154 GJ • Oil: 111 GJ • Electricity: 43 GJ • Energy intensity: 0.64 GJ/m 2 /year

AI summary The document provides energy consumption data for a heat pump, including annual energy consumption, breakdown by oil and electricity, and energy intensity. This information is likely used for evaluating the efficiency and impact of heat pump usage.

After the heat pump - May 2025
After the heat pump - May 2025 • Rated annual energy consumption: 63 GJ • Electricity: 63 GJ • Energy intensity: 0.26 GJ/m2 /year The math is significant:

AI summary The document presents energy consumption metrics for a heat pump system, including an annual energy consumption of 63 GJ and an energy intensity of 0.26 GJ/m2/year. These figures highlight the system's efficiency and performance.

154 GJ - 63 GJ = 91 GJ reduction
154 GJ - 63 GJ = 91 GJ reduction That is approximately a 59% reduction in total modeled annual energy consumption. At the same time, the electricity component went from 43 GJ to 63 GJ:

AI summary The text indicates a 91 GJ reduction in total modeled annual energy consumption, representing a 59% decrease. The electricity component specifically increased from 43 GJ to 63 GJ.

63 GJ - 43 GJ = 20 GJ increase in modeled electricity use
63 GJ - 43 GJ = 20 GJ increase in modeled electricity use So, the EnerGuide reports do support that the heat pump would increase electricity consumption. However, they also show that the home's total modeled energy consumption decreased by...

AI summary The customer reports a 20 GJ increase in modeled electricity use after installing a heat pump, but notes a 91 GJ reduction in total energy consumption. They argue the balance may be partly due to delayed billing adjustments from a cybersecurity disruption rather than solely due to the heat pump. They request a fair assessment of the situation.

4. The increase in electricity consumption
4. The increase in electricity consumption The actual meter readings show substantially higher winter electricity consumption in 2025–2026 than in the previous winter. I understand that the installation of my heat pump, weather and other f...

AI summary The document discusses an observed increase in winter electricity consumption in 2025–2026 compared to the previous winter, noting that factors such as the installation of a heat pump and weather may have influenced this increase. The author acknowledges that EnerGuide assessments do not prove billing errors but requests a review of the consumption data and its explanation.
