NY Governor Cuomo goes for clean power technology in a big way

About 57% of New York state’s electricity is generated by power stations that burn fossil fuels. Nineteen of them — ranging in capacity from 22 to 2336 MW — are located in New York City, four in Manhattan. Emissions include carbon dioxide (CO2), sulphur dioxide, nitrogen dioxide, carbon monoxide, plus a multitude of other hazardous pollutants that damage human health. Many New Yorkers live next door to these plants. For example, the photo above shows the proximity of Stuyvesant Town to Con Edison’s 736-MW East River power plant.

NY Governor Andrew Cuomo, spurred by the need to take action on the health and climate effects of burning fossil fuels, announced on January 20 his ‘Green New Deal’ for the state. The goal of the plan is 100% clean electric power by 2040, the commitment to become state law. The plan will focus on building more land-based wind and solar plants, and on targeting the states offshore wind potential.

The following bar chart shows NY State energy consumption for 2016 (latest available). Natural gas is the primary fossil fuel used to produce the state’s electricity.

To get an idea of the magnitude of the task set by Governor Cuomo, the table below shows the clean power capacity in megawatts needed to replace all the fossil fuel amounts shown in the bar chart (Btu to MWh to MW x 0.9%):

Natural Gas + Coal  . . . . . . . . . . . . 42,000 MW
Motor Gasoline . . . . . . . . . . . . . . . . 19,000 MW
All other fossil fuels . . . . . . . . . . . .18,000 MW

The 42,000 MW of electricity from natural gas is the focus of Cuomo’s green plan. In fossil fuel terms, to provide that much power from scratch would require building 50 to 60 power plants of the size shown in the photo above. Instead, the task will require building wind and solar farms. For example, if offshore wind was the only source of clean power, at least 3,500 wind turbines rated at 12 MW each would be needed to generate the 42,000 MW of electricity. By comparison, the capacity of European offshore wind farms (operational and under construction) now stands at about 21,000 MW, with another 20,000 MW on the drawing board. The map below shows where New York’s offshore wind farms will be sited. Statoil (now called Aquinor) is considering a 2,000 MW wind farm for its leased area, the grey-shaded part of Hudson North.

Governor Cuomo’s plan does not specifically mention motor gasoline. As the transition is made from gasoline to electric cars, at least 19,000 MW in additional clean electrical generation capacity will eventually be required. My guess is that a significant chunk of that capacity will be met by home or community based solar panels. The other fossil products such as distillates (e.g. diesel fuel) and jet fuel are not even mentioned in the plan.

It’s sometimes suggested that carbon neutrality can be achieved while continuing to burn fossil fuels. We (all animals) exhale CO2 with every breath. That CO2 is captured by growing plants during photosynthesis. To stay alive, we eat the plants (and the flesh of animals that also live on plants) and so regain the carbon lost to the atmosphere while breathing. That is our basic carbon-neutral economy. When we began to release CO2 by burning fossil fuels, that basic economy was thrown out of kilter. Result: the greenhouse effect and global warming. The only way to re-create a carbon neutral economy is to stop burning fossil fuels. Governor Cuomo is on the right track. He summarizes his plan in the following YouTube video (1 min 42 sec).
