NYISO VP Zach Smith on Reliability Risks from Extreme Weather, Transmission Constraints, & Electricity Economics
Episode 18: NYISO VP Zach Smith on Reliability Risks from Extreme Weather, Transmission Constraints, & Electricity Economics
12/27/21 by New York ISO
We’ve just released a new report, the Comprehensive Reliability Plan (CRP), which looks at the New York energy grid over the next 10 years and determines if there are any factors that could impact our ability to keep the lights on for all. While the report declared there are no immediate risks, Vice President of System & Resource Planning Zach Smith says the future of the grid is not so simple. To safely and responsibly tackle climate change impacts to the power grid, one must consider multiple factors together in thinking about decarbonization and planning. “We have a shifting resource mix of generation. We need to be mindful of how this big machine called the electric grid continues to operate,” Smith told Kevin Lanahan, Vice President of External Affairs and Corporate Communications, during an interview for our Power Trends Podcast. One issue, Smith said, is that as new resources come onto the grid, such as wind or solar power, older, less efficient power plants will retire. The “spinning mass” of fossil fuel-fired plants provides a reliable source of electricity that can offset the intermittent nature of solar and wind resources, which are limited due to weather and time of day. Losing oil and gas plants will require replacement by other energy resources that can offset these intermittent resources. “We’re already seeing changes on the grid. That’s going to have a real impact: some of them positive, some of them negative,” Smith said. “We’re very concerned that if we experience a heat wave, a polar vortex, our projections show we could come up short.” For more about how we are addressing a zero-emissions grid with market-based solutions, visit the 2040 Power Grid webpage.
I really don’t know what to think about the push for electrification of everything
I really don’t know what to think about the push for electrification of everything. 🔌
In many ways, electricity is a very elegant way of delivering and managing energy. For one, you can generate electricity a long distance away, ship it down an electrical wire at high voltage and relatively low amperages, and have relatively low losses. Electricity is easily controlled by electronics that drive IGBT transistors to deliver a perfect sine wave for powering virtually anything you would want with relatively low losses. Sounds great.
The question becomes where does all this electricity come from? God doesn’t send electrons bouncing down the wires, instead most power comes from fossil fuels, with a relatively smaller portion coming from nuclear and hydroelectric. Renewables barely make a dent. It’s hard to generate a lot of electricity from renewables when urban demand is so high and renewable energy is not dense or easy to harvest on demand.
Most of the big solar facilities being built these days are for show, they aren’t that big of contributions to the grid. Maybe they’ll scale up – wind is now a noticeable part of the electricity grid at times in New York State but it’s still a pretty minor player.
Despite optimistic predictions, I just don’t see how in a few years the majority of our electricity will come from renewables especially with demand surging as people replace fossil fuel heating with electric heat pumps and gasoline cars with electric vehicles. Existing plants along with additional renewables and natural gas capacity might allow these technologies to be integrated relatively seamlessly into the grid but it’s not going to decarbonize electricity at the same time.
That said, going electric has big advantages. For one it moves pollution out of our homes and our sense urban neighborhoods. Most large power plants are located in remote, rural areas where there high stacks carry pollution away. It’s also vastly more flexible and efficient, at least to motors compared to internal combustion engines. But also it is no guarantee that electrons will be generated from renewable sources.
Repairing Underground Power Cables Is Nearly Impossible
In 1989, this story about an underground electrical transmission line spread across the early internet like wildfire. It had a big impact on me as a kid, and I wanted to share it with you! I think the Scattergood-Olympic transmission line is probably LA's most famous power line, although it has now been replaced with a more modern line since 2018.
The Best Way to Imagine Alternating Current
This is a good thing, less light pollution. 💡
With the growth of electric cars and renewable energy, many cities will get priced out of street lighting, forcing them to extinguish many street lights.
This is a good thing, less light pollution. 💡
Most street lighting is only affordable now because utilities have such enormous need for spinning reserve to meet the morning ramp.
But if early morning energy prices surge with electric cars and no solar at night, cities could easily get priced out of the street lighting business except the minimum absolutely necessary.
