AI summary The text discusses the impact of net metering customers using solar photovoltaic generation on NS Power's need to maintain firm generating capacity and infrastructure. It highlights the variability of solar generation and the resulting implications for the power system and cost distribution among customers. NS Power is developing a Distributed Energy Resource Integration Roadmap in response to the Board's direction.

[Table 1](#page-13-0) summarizes the major variables examined in the analysis and their year-over-year changes. Table 1: Weather & Technological Driving Factors Category Metric 2023 2024 Change Impact on Payout Heating Degree 1 Days (HDD)...

AI summary Table 1 outlines year-over-year changes in weather and technological factors, including heating and cooling degree days, solar irradiance, EV and heat pump ownership, and electric heating ownership. These variables impact payout and are analyzed for their influence on energy use and efficiency.

4. Vehicle Electrification and Customer-level Impact Perspective To provide perspective, the change in payout energy (581,577 kWh) is marginal converted to the individual customer level (approximately 110 kWh per year per customer).

AI summary The document discusses the impact of vehicle electrification on individual customers, noting that the change in payout energy (581,577 kWh) translates to a marginal increase of approximately 110 kWh per year per customer.

AI summary NS Power explains the 30.9% decrease in net metering customers by citing factors such as cost, incentives, and financing. The 26% decrease in nameplate capacity is attributed to reduced solar installations, though average capacity increased. A cybersecurity incident in April 2025 caused a delay in payouts, which were later resolved with manual meter readings. Spikes in August and November 2025 were due to the availability of true meter readings after the incident.
