Data & signals for a changing grid.

A single chart rarely explains an energy trend. This guide points to indicators that add context to questions about storage, transmission, and grid reliability.

Choose a lens.

Use the filters to explore different kinds of evidence. These are measurement prompts, not live statistics.

Build & connect

Interconnection queue status

Track projects by stage, withdrawal, study milestones, and eventual completion. Queue volume alone does not equal future capacity.

Build & connect

Transmission project milestones

Look at planning approval, permitting, construction progress, and expected in-service dates together.

Operate

Hourly demand and net load

Hourly data shows when the system needs power and how that need changes as variable resources contribute.

Operate

Congestion and curtailment

These measures can point to location-specific limits, but each requires careful definitions and comparisons.

Outcomes

Outage frequency and duration

Reliability indicators help track service interruptions. Weather, reporting rules, and local system characteristics affect comparisons.

Outcomes

Customer costs and bill impacts

Separate energy, capacity, transmission, and distribution components where data permits, and identify who bears each cost.

Data literacy note

Check the unit, date, and boundary.

Before comparing two charts, check whether they cover the same geography, time period, and unit. Reported capacity, energy delivered, and project pipeline are different quantities.

When possible, trace a chart to the original data and read its definitions. A footnote can change the meaning of a headline.

Three checks

What is measured?
When?
Across which system?

If one answer is missing, treat a comparison as preliminary.
