About Us
Where your energy comes from
We deliver energy; most of it we do not generate. Here is how electricity, natural gas, and district energy reach your meter — and how the mix behind them is changing.
Three Services, One System
Each service has its own supply chain, market, and infrastructure — all converging on one crowded, vertical city.
Electricity
We buy power on the regional wholesale market from a mix of generators — with a fast-growing share of wind, solar, and hydropower — then deliver it over our transmission and distribution grid.
Natural Gas
Gas reaches the city through interstate pipelines and is delivered through thousands of miles of mains we inspect, maintain, and modernize year-round.
District Energy
Our district energy network — one of the largest in the country — heats and cools many of the city's most iconic buildings from central generating stations.
A Cleaner Mix
Getting cleaner every year
Supporting the region's climate goals means reshaping where energy comes from, not just how it is delivered.
- New transmission to carry renewable power into the city
- Battery storage to bank clean energy for peak hours
- Energy efficiency programs that shrink demand at the source
- Research into low-carbon alternatives for the gas system
