Emissions reduction

Startup Singularity is sharing data on hourly U.S. power-grid emissions. It wants energy markets, governments and companies like Google and Microsoft to use it — and to disclose their own data too.

Grid-enhancing technologies enable us to get more out of existing power lines. Here’s an in-depth look at one such technology: dynamic line rating.

Federal regulators have proposed major reforms to clear huge backlogs of solar, wind and storage projects waiting to interconnect to U.S. power grids.

Guides and how-tos

Canary Media defines the concepts that are key to a clean, distributed electricity system, from "behind the meter" to "balancing the grid."

Policy & regulation

A new federal proposal would task grid operators, states and utilities with planning a grid that can support clean energy over the long term — and fairly share the costs of building it.

Without major policy reforms and grid upgrades, much of the 1.4-terawatt queue of solar, wind and battery projects may never get built, two new reports find.

Utilities

Cheap renewables are a good thing, but customers will likely be stuck with a hefty bill for grid upgrades.

Transmission

Divvying up costs between MISO's north and south regions could solve a long-running fight over who pays for new transmission lines. But will the plan pass muster with federal regulators?

Startup TS Conductor says its product can boost electricity transmission without costly rebuilds. Policy shifts from U.S. regulators would help.
