Ep.27: Master Class in Electricity Markets with Rana Mukerji

In our latest podcast, we sat down with Rana Mukerji, NYISO’s SVP of Market Structures, to learn about his journey from growing up in Calcutta, India to becoming widely regarded as one of the ­­industry's leading designers of electricity markets. We ask Rana about his past career experience working for General Electric and ABB, and how the markets must evolve to accommodate a new set of renewable resources while keeping the grid reliable.

Wholesale competitive electricity markets are an essential component of grid reliability in New York. Markets play a critical role in reconciling supply with demand which must be in perfect balance at all times. 

As decarbonization policies drive an increase in intermittent, weather-dependent energy such as wind and solar, it has never been more important to understand markets’ contribution to reliability. There are few people more qualified to explain this evolution than NYISO Senior Vice President of Market Structures Rana Mukerji. Rana was instrumental in the early research and data simulation that informed the structure of markets in New York. This edition of our Power Trends podcast is a master class on the wholesale electricity markets that the New York ISO administers and how the energy, capacity, and ancillary markets work together.

Mukerji identifies two primary shifts affecting the market. First, new renewable resources coming onto the grid are driving down energy prices because of their low variable costs – particularly because they have essentially no fuel costs. At the same time, the system is becoming more volatile because that supply is weather dependent. To maintain reliability, the market assigns a premium to ancillary services that can balance: “The premium value of the future energy supply is flexibility,” he explains. “We are repricing reserves to make it more attractive to perform when needed and rewarding that flexibility.” 

“It’s going to be a vastly more complex grid, but it is going to really drive our transition to a decarbonized and sustainable future,” he adds. 

Rana’s path to the NYISO began decades ago with his first plane ride from Calcutta, India to New York City. From there he boarded a bus to Troy, New York where he began his graduate studies in electrical engineering at Rensselaer Polytechnic Institute (RPI) on a full scholarship and later worked as an energy consultant with GE. Today, he uses his deep knowledge and experience in economics and engineering to prepare markets for the grid of the future. 

In this podcast, Rana explains how the markets are changing, and how to make sure the grid stays reliable as we get closer to a 2040 goal of a zero-emissions grid.
