Hourly net energy flows at **Onslow South**, a key transmission point in Nova Scotia's grid, reported in megawatts (MW). Onslow South is a major node on the provincial transmission system connecting mainland Nova Scotia to the export path toward New Brunswick and, indirectly, other Maritime markets. This series tracks how much power moves through that corridor each hour — important for transmission planning, congestion analysis, and understanding north–south flow patterns within the province.
Data comes from Nova Scotia Power OASIS monthly reports. Fourteen yearly source files are merged (2012–2026).
**Time coverage:** 2012–2026 (hourly).
**Known gaps:** Calendar year **2021** was not published on the NS Power portal and is absent. The 2026 file is year-to-date.
**Key columns:**
- `Hour Ending` — timestamp (hour ending)
- `MW` — net energy flow at Onslow South
- `_source_year` — calendar year of the source file
**Rows:** ~115,367 hourly records.
This dataset appears to contain hourly energy production data for a specific year. The columns indicate that each row represents an hour of data, with values for the end time of the hour, the amount of electricity produced (MW), and the source year.
The quality scores suggest that this dataset is generally accurate and complete, but may have some minor issues with uniqueness and consistency. The overall score of 98.13/100 indicates a high level of data quality.
1. Analyzing historical energy production patterns
2. Modeling energy consumption for forecasting purposes
1. Data only covers one year, may not be representative of broader trends or multiple years
2. Values are for hourly production, may need to be aggregated for larger time intervals
