2.     Fraud:  Too many people have been victimized by glib sales reps with promises of cheap electricity flowing in an unending stream only to discover that, as is so often true, “it ain’t necessarily so”.  They’ve been locked into unwanted term contracts or there’s a catch – some utilities will give you the great rate only if you meet a usage minimum; basically, the “rate” is, in actuality, a “bulk purchase” discounted fee – or they paid a deposit never to hear from the rep again.
Wind and solar power are non-dispatchable. Such power is normally sold before any other bids, at a pre-determined rate for each supplier. Any excess is sold to another grid operator, or stored, using pumped-storage hydroelectricity, or in the worst case, curtailed.[116] Curtailment could potentially significantly impact solar power’s economic and environmental benefits at greater PV penetration levels.[117] Allocation is done by bidding.[118]

While there is a very strong argument for providing cheap, subsidized power for the poorest in society, this should be done in a way that limits subsidies to the really deserving and the system as a whole needs to be able to charge tariffs that on average cover all costs. If this doesn’t happen then all manner of bad things will follow. As you might guess prices have been set too low by African governments. These subsidies have also been made too widely available, benefitting the elite and middle classes more than the poor (who, not having good access to the grid in the first place, don’t have ready access to these subsidies).

Canadian electricity is cheap at 10 US cents per kilowatt hour, which is reflected in their high average electricity usage. US electricity prices at 0.12 $/kWh are also quite cheap internationally. In India and China they are very cheap. The UK is in the middle at 20 cents. It’s relatively expensive globally but not too bad for Europe, where most countries pay a high share of tax on their power.
The simplest model for day ahead forecasting is to ask each generation source to bid on blocks of generation and choose the cheapest bids. If not enough bids are submitted, the price is increased. If too many bids are submitted the price can reach zero or become negative. The offer price includes the generation cost as well as the transmission cost, along with any profit. Power can be sold or purchased from adjoining power pools.[112][113][114]

The weakest S&P 500 subsector during 2014 was Oil and Gas Drilling, down 46%, which wasn’t very surprising, considering the price of oil dropped 50% from its peak in June through the end of the year. That subsector has risen 6% this year through Monday’s close, showing that there’s plenty of buying taking place. Most other subsectors within energy declined last year, but only three have risen so far in 2015.
The two most common distinctions between customer classes are load size and usage profile. In many cases, time-of-use (TOU) and load factor are more significant factors than load size. Contribution to peak-load is an extremely important factor in determining customer rate class. Consumer loads may be characterized as peak, off-peak, baseload, and seasonal. Utilities rate each load differently, because each has different implications for a power system.
Power generation projects, which have to sell their power to these bankrupt utilities, require creative financing structures to get around these problems. In a bid to reduce their risk when financing these projects, bankers employ financial tools like put call options agreement or World Bank partial risk guarantees. The problem is these tools add complexity and cost which end up being passed on to the end-user or worsen the financial state of the power utility.

It’s very important to do your own research to understand the business focus of the company you are considering, as well as tax advantages (and possible disadvantages) if the company is a limited partnership. For example, Seadrill Ltd. SDRL, -1.72%  provides offshore-drilling services worldwide. Seadrill Partners LLC SDLP, -3.22%  operates offshore-drilling rigs under specific contracts with several major oil companies, including Exxon Mobil Corp. XOM, +0.17%  and Chevron Corp. CVX, -0.43%  
In states with energy choice, the open market is not only for residents. Businesses also can take advantage of pricing and plans available through an energy supplier. In some states, only business customers have energy choice. Across the United States, the average business consumes 6,278 kWh of electricity per month and receives a bill of nearly $655.  
Unlike with long-term plans, monthly, variable rate (no-contract) plans have no cancellation fees. You won’t have to pay a penalty if you decide to take your business elsewhere because you found a better deal. Plus, you won’t be left paying more than you should if the market rate for energy trends down. However, if the market prices rise, you’ll have to pay more than those who are in-contract.
