What's Delaying the Completion of Energy Projects in New York?

New York urgently needs new generation to meet rising demand. While the NYISO has made progress in streamlining its interconnection process, data shows that clearing interconnection studies does not guarantee projects move forward to construction.

Environmental Advisory Council Discusses Scenario-Based Planning, Institutional Decarbonization at May Meeting

The NYISO’s Environmental Advisory Council (EAC) recently met virtually for a discussion on grid reliability, the NYISO’s expansion of scenario-based system planning, and the feasibility of institutional decarbonization and electrification.

What an “All-of-the-Above” Energy Strategy Looks Like and Why It’s Essential

New York is facing a monumental challenge: It must deliver an energy system that is reliable, affordable, and clean, all while maintaining the diversity of resources needed to achieve those goals.

A Note from NYISO President & CEO Rich Dewey on Power Trends 2026

The transformation now underway in New York’s electric system stands alongside two defining periods in our history: the original buildout of the grid during the turn of the last century, and the sweeping expansion that followed World War II. In each of those moments, the Empire State met a surge in economic growth and technological change with vision, investment, and a commitment to reliability.

Keeping the Lights on in Unprecedented Times: Looking Back at Sequestered Grid Operations During COVID-19

In March 2020, during the early days of the COVID-19 pandemic, people around the world were adjusting to the new normal of working at home. Meanwhile, 37 NYISO staff were adjusting to living – and sleeping! – at work.

Podcast Ep. 44: Wind and Solar Are Rising; Udayan Nair on What It Means for the Grid

Wind and solar resources are providing more clean, low-cost electricity to the grid than ever before, but the intermittent nature of renewable generation requires careful planning.

NYISO’s Grid Alert System Keeps New Yorkers Informed

As summer draws near, the NYISO’s grid alert system will be essential for keeping the public informed about operational changes to the bulk electric system.

Wholesale Electricity Prices Down as Weather Warms

Wholesale electricity prices have dropped considerably in New York after a particularly frigid winter which resulted in soaring demand and operational challenges resulting in the need for emergency procedures to operate the grid reliably.

Modernizing Our Generation Fleet: Replacing Aging Generation Can Cut Emissions, Costs

In a time when reducing the grid’s carbon emissions is a priority, building and upgrading gas plants may seem counterintuitive. But in fact, it is a strategy that can support the ongoing build-out of renewables, including solar, wind, and battery storage.

CRP: Expanded Planning Framework Needed to Capture Emerging Risks

The electric grid is undergoing a transformation unlike anything seen in its history. New York’s ambitious climate goals, rapid electrification, new renewables, and the rise of large-scale energy users are reshaping demand patterns and resource availability.
