A megawatt is an instantaneous measure of power.
The new 1,310-megawatt deal will supply enough electricity to power about 530,000 homes in California.
The OpenHydro tidal power machines will be used for a 200 megawatt site south of Scotland’s Orkney Islands.
"For every megawatt of solar panel capacity, you'll need a ton of NF3 for cleaning the equipment," Pilgrim says.
Solar power has an intuitive appeal under the blistering south-western sun, but it is still expensive per megawatt.
The East Kentucky Power Cooperative announced plans five years ago to build the 278-megawatt plant, and it obtained permits from the Kentucky Public Service Commission.
With their receiver tuned specifically to pick up signals from this one megawatt transmitter, they were able to generate 60 microwatts of power.
Southern California Edison leased the roof of this massive warehouse in Fontana, California, to install a 2.44-megawatt solar array in 2008.
Until the announcement of the Ordos project, the largest single photovoltaic power plant was the 550-megawatt Topaz solar farm to be built by First solar in California.

The best thing state residents can lay claim to is generating three-quarters of a million megawatt hours of wind energy annually, the 19th best amount for this category.
Utilities want to hook up the 1.8-megawatt machines to the grid in the middle of cities (to save the energy otherwise lost in transit), so they need to run clean.
Prices have fallen from around $60 per megawatt-hour last summer to $20-30 this summer. They are strongly tied to the prices of natural gas and coal, which have both fallen too.
For example, it recently won an order to provide a 2.2 megawatt-hour battery, the size of a shipping container, for use in tests to back up a Chinese coal-fired power station.
