Texas & Northeast States Annual Generation Capacity (MWh)

How to Read This Chart

This line chart shows annual electricity generation capacity for Texas and selected Northeast states from 2019 through 2024, measured in megawatt-hours (MWh). Each line represents a single state, allowing direct comparison of how installed generation capacity has changed over time across regions. The horizontal axis shows the calendar year, while the vertical axis shows the total installed generation capacity in each state. An upward trend indicates capacity additions, while flatter or declining lines indicate slower growth or net retirements. The relative distance between lines highlights differences in scale between Texas and individual Northeast states.

Why This Matters

Comparing generation capacity across states highlights regional differences in how electricity systems are expanding and modernizing. Texas shows significantly higher capacity levels and faster growth than individual Northeast states, reflecting differences in market structure, population growth, resource availability, and investment patterns. This data helps policymakers, utilities, and market participants understand where new generation is being built, how regional supply capabilities are evolving, and how resilient different power systems may be to future demand growth. For researchers and consumers, it provides context for why electricity prices, reliability challenges, and energy transition pathways can vary widely by state and region.

Key Insights

The following highlights are derived directly from the most recent available data in this dataset using standardized calculations. Metrics reflect aggregate generation capacity by region and are computed from the underlying time series. Unless otherwise noted, comparisons are based on the most recent complete reporting year and prior comparable periods. These highlights provide a concise snapshot of regional differences in generation capacity growth.
