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]
When it comes to pinpointing specific months rather than seasons, every part of the country has its own highest- and lowest-demand months. For example, hotter states, such as Texas, have their lowest demand anytime between December and March.[2] When it comes to your own location, you can determine typical demand trends by taking a look at your area’s weather patterns or your billing records that showcase your personal monthly demand levels.

The problem is that across Africa, the vast majority of the power utilities are effectively bankrupt. Another World Bank study (pdf) on African Utilities shows that only two of the 39 African utilities surveyed, in the Seychelles and Uganda, were able to generate enough cash to cover both their operating costs and capital expenditures necessary to invest in the maintenance and expansion of the grid. In fact, only 19 of the 39 companies were able to generate enough cash to cover their day-to-day operating costs. It means the rest were not even able to pay everyday costs, like salaries, in full.
Snowpack, streamflows, seasonality, salmon, etc. all affect the amount of water that can flow through a dam at any given time. Forecasting these variables predicts the available potential energy for a dam for a given period.[124] Some regions such as the Egypt, China and the Pacific Northwest get significant generation from hydroelectric dams. In 2015, SAIDI and SAIFI more than doubled from the previous year in Zambia due to low water reserves in their hydroelectric dams caused by insufficient rainfall.[125]
 1.     Contracts:  Before, there were no contracts.  You signed up or you didn’t.  When it’s the only game in town, you have to play by their rules.  Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.

Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those whose power is proved by municipally-owned utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.
But competition didn't necessarily end up cutting prices, according to the report. One contributing factor is confusion among customers as they try to choose among scores of retail electricity providers and the overwhelming variation of plans, leading many to just stick with familiar companies rather than look for better deals, according to the Texas Coalition for Affordable Power .
Prices for any single class of electricity customer can vary by time-of-day called TOU or time of use or by the capacity or nature of the supply circuit (e.g., 5 kW, 12 kW, 18 kW, 24 kW are typical in some of the large developed countries); for industrial customers, single-phase vs. 3-phase, etc. Prices are usually highest for commercial and residential consumers because of the additional costs associated with stepping down their distribution voltage. The price of power for industrial customers is relatively the same as the wholesale price of electricity, because they consume more power at higher voltages. Supplying electricity at transmission-level high voltages is more efficient, and therefore less expensive.
Fixed-rate plans: Fixed-rate plans give customers more stability for their monthly energy bills because the rate a customer signs up with is the rate he or she pays for the length of the plan’s contract. Most fluctuation comes with usage, though transmission and delivery charges and local fees also can change.. Because a fixed-rate plan sometimes spans two-three years, these plans often require a customer credit check and can include early cancellation fees. Fixed-rate plans, because of the continuing market volatility, probably are the best choice for many consumers.

In Houston, 0% of people have switched to a plan that has some renewable energy component to it. Another 0% have switched to a plan that is partially renewable, while 0% have switched to a plan that powers homes completely by renewable electricity. This of course means that 100% of people have remained on a plan powered by traditional sources of electricity such as coal or nuclear power.

The freedom to choose your energy rates in Maryland is not only available in homes but also to commercial customers. In fact, more than 90% of large businesses in the state have enrolled with alternative suppliers. This competition between energy suppliers to provide lower prices for businesses could be why commercial electric prices in Maryland are lower than the national average this year. If the same competition between suppliers existed for residential customers, prices might also decrease. However, without participation in energy choice, suppliers are not forced to compete for your business. Want to see the available rates? Enter your ZIP code above.

There are many reasons for this but I’d like to focus on African power utilities. Power utilities are a very important part of the chain for delivering electrical power to end users. One of their key roles is to purchase power that has been generated by others, sell it on to end-users and to collect revenues. They are vital for extending grid-based power to consumers and to ensure regular and efficient power supply. As they collect money from end-users and pay it on to other players in the system, they are also vital in ensuring money flows through the entire power sector.

On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for.  You’ll have peace-of-mind.  If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
Where should you shop for electricity? Houstonians have the power to choose from an overwhelming variety of energy suppliers, plans, and options. If you live in the Houston metro area and your local electric utility is CenterPoint, over 50 different retail electricity providers currently offer electricity plans in your area. Each of these electricity providers offer sites, tools, and information on how to switch plans and providers. However, their information is often filled with electricity rates that are difficult to compare because of things like introductory rates, bill credits, narrow usage levels, unexpected fees, and legalese buried in the EFLs. Fortunately, Houston homes and businesses have electricity shopping options that make the process much simpler.
There’s some smart money placing big bets on a rebound for oil. Blackstone Group LP BX, +0.75%  President Hamilton “Tony” James said last month that the company was “scrambling” to invest up to $10 billion in energy companies, according to Bloomberg. Blackstone CEO Stephen Schwarzman said during the company’s earnings call on Jan. 29 that the majority of Blackstone’s energy investments were “oil-price agnostic, including energy-transportation infrastructure where we have off-take agreements, merchant power, renewables and other types of energy-oriented investing.”

Texas electricity deregulation has given millions of Houston residents and businesses the power to choose the cheapest electricity rate. According to ERCOT, over 92% of Texas homes and businesses who live in deregulated areas have switched electric companies since deregulation began in 2002. Even though electric choice in Texas has been hugely successful for energy savings, customers are still confused by the options, terminology, and overall process of switching electric providers.
Even though customers in deregulated Texas markets routinely pay more for electricity, there is a bright spot. The gap between the average price paid for electricity between deregulated and regulated market has shrunk to 8.8 percent. In 2006, customers in deregulated cities were paying nearly 47 percent more for electricity than their counterparts in regulated cities.

Once you sign up for your new energy plan, your local utility will be notified of the change and begin your service from the alternative supplier at the beginning of your next billing cycle. Upon starting your energy supply service, your utility company will include this charge on your energy bill and continue to charge for the delivery service portion of your bill. Why? Because although your supplier may offer you a competitive rate for electricity supply, your utility is still in charge of the infrastructure that delivers energy to your home – such as power lines and energy meters.
