How does flexibility help balance the modern energy system?
The energy system has fundamentally shifted from large centralized power plants to a world where decentralized loads must actively participate in the grid. Flexibility enables NISO to access the resources it needs to keep supply and demand in perfect balance at all times, turning consumers and distributed assets into essential partners rather than passive users.
From centralized generation to distributed participation
The traditional energy model relied on a handful of large power stations controlling generation to match demand. That system no longer works in a modern grid. Decentralized energy sources—solar panels, EV chargers, industrial processes, home batteries—now shape how electricity flows, and they must be coordinated, not ignored.
As Jonathan Wisdom explains in the episode, flexibility is what makes this new architecture possible. Without it, the grid operator has no levers to pull when demand spikes or generation drops unexpectedly. With it, NISO can call on hundreds of distributed resources to respond in real time.
Balancing supply and demand in real time
The core challenge for any grid operator is simple: every second, electricity generated must equal electricity consumed. A single major imbalance can trigger blackouts. Flexibility gives NISO immediate access to demand-side resources that can shift their consumption up or down on demand, filling gaps that generation alone cannot cover.
This is why the Power Responsive program, which has been operating for around 10 to 11 years, matters so much. The program engages consumers and businesses directly, helping them bring their flexibility to market and participate in the energy system like never before. Whether it's a factory pausing production for 15 minutes, an EV fleet charging strategically, or a home battery discharging at peak hours, each act of flexibility reinforces grid stability.

What are the specific targets and goals for Power Responsive by 2030?
NISO currently has around 200 megawatts plus of flexibility participation and targets reaching approximately 950 megawatts to 1 gigawatt by 2030, representing a significant expansion of demand-side resources in the energy system.
Who does Power Responsive want to bring into the conversation and involve?
Power Responsive wants to work closely with domestic users through suppliers and aggregators, but particularly with industrial and commercial actors who can provide substantial flexibility resources to the grid.
What is the Power Responsive program and what is its mission?
Power Responsive came to fruition around 10 to 11 years ago and is about engaging the market and understanding what demand-side participation could look like. It has evolved to help consumers bring their flexibility to market and participate in the energy system like never before.
