Could you give an example of how it would be exploited? I want to know more what an energy company would do in such a situation. Is there existing situation where the government regulates the price of things?
Well, my main concern about such a thing is that it would have to be very complex to work. And complexity leaves the way open for more loopholes to get inserted by lobbyists and whatnot.
My impression with cap and trade is that it doesn't need to be nearly as complex to work. As with all government legislation, of course, there's always the possibility for abuse, but it seems to me it's somewhat easier to avoid that.
As for a current situation, power prices are actually very tightly regulated in many places in the US.

Could there be a similar regulation based on carbon emission? Suppose a power plant has high carbon emission, the government can have a forumla and calculate the maximum increase in energy price. For plants that are really bad, the rate limit might less than 1, meaning they have to lower their price. These increases and decreases are based on the current price. Any customer could check their bills.
The nice thing about cap and trade is that most of this is determined more-or-less automatically. I tend to think it's usually easier (and thus less prone to abuse) to let the market manage the details, and just regulate the market, than it is to micro-manage things like prices.

Suppose a law is written with the intention to reduce carbon emission, could the law have a clause saying that the company cannot try to shift the cost to the customer, that the company will take the responsibility itself? This allows the customers to sue the companies if they find the companies trying to shift the burden.
I don't think this really makes much sense. Bear in mind that many consumers will
benefit from their power plants selling carbon credits (the more efficient ones should have excess credits).
I suppose it would make good sense to ensure that the power companies don't retain windfall profits by using the excuse of carbon credits to raise prices more than is required to pay for the credits. But I don't think it is entirely reasonable to expect no increase in areas that have poor efficiency.
I'd have to look into the current cap and trade proposal more specifically, but the way to make this really powerful would, I think, be to push the electrical grid in the direction that neighboring power stations can compete for customers. That way if power company X is really inefficient, and rises its prices to cover the costs of the carbon credits, it will lose its ability to sell its electricity on the market, and thus get pushed out.
The intermediate alternative that we have today in many places is that the prices power companies are allowed to charge are very strictly regulated.
