There's a new product on the market from a company called GridPoint. It functions like a TiVo for electricity, allowing you to purchase and store electricity during offpeak hours, and thereby shaving money off your monthly electricity bill. Check out the article about GridPoint on CNN.
The device, called GridPoint Protect, is the size of a small file cabinet and connects to the circuitbreaker panel. (The company also offers a lower-capacity version designed for homes, which costs $10,000.) A built-in computer powered by a Pentium chip will make intelligent purchase decisions, buying when prices are low, then storing the electricity for later use. That will make it possible to run your company during the workday with cheaper electricity that you purchased at 3 A.M. Corsell, 28, estimates that his device will shave a business's electric bill by about 15%. Assuming monthly charges of $2,500, the system would pay for itself in less than four years.
Because it stores electricity, it can double as a backup generator that is safer and faster than many models currently available.
Anyway, it's an interesting concept. We'll see if it actually flies.
