Prices and demand are shown for six Regional Transmission Operator (RTO) markets: ISO New England (ISO-NE), New York ISO (NYISO), PJM Interconnection (PJM), Midwest ISO (MISO), Electric Reliability Council of Texas (ERCOT), and two locations in the California ISO (CAISO). In the second tab immediately below, we show monthly and annual ranges of on-peak, daily wholesale natural gas prices at selected pricing locations in the United States.


Wholesale electricity and natural gas prices were much lower this January than in years' past, particularly in the Northeast. The low wholesale natural gas prices this January were even more pronounced than the fall in wholesale electricity prices. Electricity system daily peak demand this January was lower than last year in all regions except California (CAISO), Progress Florida, and the Bonneville Power Administration (BPA) footprint. The tides are formed due to the gravitational force of attraction between the earth, sun and moon.
The world's first successful tidal powered electric plant, which spans the Rance River generates a peak 240 megawatts a day enough to power 16,000 homes in the United States. Today this is the only tidal power station in the world since it is very difficult to find good tidal sites. Below we look at monthly and annual ranges of on-peak, daily wholesale prices at selected pricing locations and daily peak demand for selected electricity systems in the Nation.
Also shown are wholesale prices at trading hubs in Louisiana (into Entergy), Southwest (Palo Verde) and Northwest (Mid-Columbia). The range of daily natural gas prices is shown for the same month and year as the electricity price range chart.
A combination of warmer-than-normal temperatures across the Northeast, additional pipeline infrastructure, and the generally well-supplied and low-priced natural gas environment led to regional prices just a fraction of what happened over the last several years.
California loads peaked during the first week of the month (though loads were low compared to other times of the year), as cool weather and heavy precipitation blanketed the state. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity.


The range of daily prices and demand data is shown for the report month and for the year ending with the report month. In addition to the RTO systems, peak demand is also shown for the Southern Company, Progress Florida, Tucson Electric, and the Bonneville Power Authority (BPA). Wholesale electricity prices are closely tied to wholesale natural gas prices in all but the center of the country. Progress Florida's 10,764 megawatt (MW) peak demand was 18% higher than its peak last January, though winter loads are considerably lower in this region than those occurring during summer months. Refer to the map tabs for the locations of the electricity and natural gas pricing hubs and the electric systems for which peak demand ranges are shown. Therefore, one can often explain current wholesale electricity prices by looking at what is happening with natural gas prices. This difference in temperature can be used to extract heat which in turn produces electricity.
The most promising system in the UK has been developed at the National Engineering Laboratory.
Small scale experiments have shown that it might be possible to build large ocean thermal energy systems but they would be quite expensive.
