Large-scale wind has had more success, and the state is pushing for more ; about 30 wind farms are planned upstate. A second site near the Rockaway Peninsula in Queens is in the works but is years away.
The cost of building wind and solar plants has fallen, but these power sources are intermittent. Until more storage is plugged into the grid, like batteries or pumped hydro plants , which pump water into reservoirs to store power for later use, other generators must be available to supplement solar and wind power.
New York City has about 16 such plants, mostly around the waterfront, which spring into action on the hottest days of the year or if transmission lines or power plants upstate malfunction. Some sit on barges, and all are designed to switch on quickly. The trade-off for the rapid response is usually higher costs and carbon emissions.
Kauffman, the energy czar. The entire system was designed to meet demand extremes and handle the worst-case situation. While batteries are improving , most electricity is used the instant it is created. The team constantly calculates how much power is needed and which plants can produce it at the lowest cost. Every five minutes, a computer system directs plants to dial up or scale down production to ensure enough electricity is available to keep the lights on without overloading transmission wires.
If the system is out of balance or the flow of electricity is destabilized, it can damage equipment or cause power failures. Operators undergo psychological evaluations to ensure they can handle stress, and they spend weeks every year inside simulation labs preparing for a hurricane or cyberattack.
Still, the No. Jon Sawyer, the chief system operator for Nyiso, said that today, computer systems receive 50, data points about every six seconds, and operators monitor regional activity on a 2,square-foot video wall. The biggest daily variable is weather. Storms can flood equipment, and bright, hot days can cause transformers to overheat and customers to crank up air-conditioners. Leaning on solar and wind means a greater dependence on weather, just as weather patterns have become less predictable.
Nyiso has developed sophisticated tools using climate data to predict how much power each wind farm will generate and to find ways to balance the system if the wind suddenly dies down, Mr. A: The Federal government, through the Federal Energy Regulatory Commission , regulates interstate power sales and service. State governments, through their public utility commissions or equivalent, regulate retail electric service as well as facility planning and siting.
Q: Where can I find out about State incentives for renewables? Q: What is a national corridor? Department of Energy DOE to conduct a study every three years on electric transmission congestion and constraints within the Eastern and Western Interconnections. Based on this study, and comments concerning it from states and other stakeholders, the Secretary of Energy may designate a geographic area experiencing electric transmission capacity constraints or congestion as a "national interest electric transmission corridor" National Corridor.
The National Electric Transmission Congestion Study examined transmission congestion constraints across the Nation and identified areas that are transmission-constrained. Based on this study, two National Interest Electric Transmission Corridors were designated in , but they were invalidated by a federal appeals court in It did not make recommendations concerning existing or new National Corridor designations.
The National Electric Transmission Congestion Study released in September seeks to provide information about transmission congestion by focusing on specific indications of transmission constraints and congestion and their consequences. The study focuses primarily on historical trends over the past few years, and looks into the future to the extent possible. Q: Are we connected to other countries? A: The Northeast blackout of August 14, made the point clear — the North American electric system is interconnected.
See final report. Indicators point to increased trade in electric energy between the U. This increase in trade is anticipated to spur economic benefits and improve operational flexibility, especially in the context of the reliable operation of the bulk transmission system.
Why do outlets have three holes? Why do we have AC electricity? Can we harness lightning as an energy source? Can we have wireless transmission of electricity? Where does electricity come from? What is the "grid"? How much electricity does a typical household use? How did the electric system evolve? What does the future look like? Who owns the electric system? So why does this all matter? But surely this foreign ownership has major implications for the culture and performance of the companies?
As an ex-employee of one of the gas networks at the time owned half by SSE and half by Canadian pension funds I can remember feeling pleased to be part of a company with was part of and contributed to the UK economy.
And I can imagine many people feeling the same way — all staff have are the purely financial drivers of pay and benefits to make them perform. Where is the personal ownership and pride? Have you wondered what goes on behind the scenes of electric power delivery in America? This post explains who is controlling the flow of power on the grid and who is policing to ensure the reliability requirements are met.
So, who is dispatching the megawatts and megavars from generators that gets sucked up by reactive and active loads in the grid? The map below shows the balancing authorities. Figure 3 illustrates the power grid operators. In most cases, the owners of generation and transmission facilities hand-over the controls to these operators.
They do this to avoid monopoly by any one entity. Some of the big operators and the customers it serves are as of June :. CISO : 39 Million people.
