The Cost of Energy - October 16, 2012
PJM Interconnection's Coverage
On the spinner below, you can check the live wholesale price of electricity per megawatt hour. The data is live from PJM Interconnection, which serves much of the East Coast, as can be seen in the map to the right.
One interesting feature of the spinner and graph is that they change color depending on the price of energy at that time. The image of the map was taken in the evening, so the blue colors represent relatively low costs of about $30 per megawatt-hour.
When energy demand peaks, usually during the afternoon, the wholesale price of energy can reach upwards of $60 per MWh. Wholesale energy prices can more than triple over the course of a day!

Have you ever wondered what Penn's energy consumption looks like day to day?
Facilities and real estate has great energy resources online, which you can find here. Log in with your Penn ID and password, and take a look at the live graphs!
On this page, you can see the day's energy usage compared with last year's. Further down are graphs of total monthly energy usage. It seems that July was the highest month in terms of energy consumption, with 37,000 megawatt hours used at Penn. At roughly $40 per megawatt hour, Penn had an electricity bill of about $1.5 million in July alone!
You can also view energy consumption by building, so be sure to check out the stats for where you live and monitor usage over time.
