Some manufacturers lay out a grid with price versus features, placing competitive products on the grid along with the proposed new product.
FORBES: Pricing Part 3: How Does A Brand Know When The Price Is Right?
He gave big industrial customers the freedom to buy electricity under contract from the cheapest provider, or directly from the national grid at a spot price.
One likely application of the eneGoon is storing electricity drawn from the power grid when prices are low and using the stored juice when the price of electricity on the grid is high.
Power generation operates in a free market (subject to all the usual rules on safety etc) and the price which the grid can charge for carrying the power is regulated.
FORBES: Which Should We Have: Public Utilities Or Regulated Private Monopolies?
Already Jenkins has been doing some basic (by gas or electricity standards) arbitrage plays such as contracting for capacity at known chokepoints in the national telecommunications grid to take advantage of price spikes, as well as selling short in areas with a looming glut.
If you installed solar panels then that electricity was sold to the grid at about four times the normal price.
FORBES: Green Self-Sufficiency Isn't Actually Self-Sufficient
But huge investments in hydropower in Bhutan (in return for the guaranteed supply of fixed-price electricity into India's grid) helped both countries.
ECONOMIST: Big developing countries are shaking up the world of aid
He said the distributed generator should get the same price as the generator of the power grid.

Clearly, trying to produce such an extraordinary product as a laptop that is kid-proof and capable of working in jungles, deserts or the bush, miles from the nearest grid connection, and all for the cheapest possible price, has concentrated minds remarkably.
We can do this at a price which is viable for a few off grid applications.
Solar PV is coming down in price so quickly that as its supporters insist, it will be directly price competitive with coal fired electricity from the grid in the next few years.
As feed-in tariffs expand to countries around the world, allowing early adopters a premium price for the green electricity they generate and sell back to the grid, the collection technologies will become ever more efficient and cheaper.
Information about the source, price and environmental impact of power is unavailable for most of the power grid.
Price transparency will also allow micropower plants to buy and sell power on the grid as demand dictates, so improving the grid's reliability.
Depending on the delta between the price of electricity stored and the price of electricity avoided by using the stored kilowatts rather than power from the grid, the investment in an eneGoon system could be a slam dunk.
They're guaranteed a price - a feed-in tariff - for their electricity when they sell it into the grid for 20 years.
If the price signal is right, people who own generating devices can make economic decisions to take part in the grid.
