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. Curtailment could potentially significantly impact solar power’s economic and environmental benefits at greater PV penetration levels. Allocation is done by bidding.
In terms of renewable sources like solar and wind, weather impacts supply. California’s duck curve[cite] shows the difference between electricity demand and the amount of solar energy available throughout the day. On a sunny day, solar power floods the electricity generation market and then drops during sunless evening, when electricity demand peaks.
Should you choose a short-term, long-term, month-to-month, or prepaid plan? The short answer: it depends on your specific needs. How long do you anticipate living at your location? Are you deciding in the peak season (summer in Houston) or off season? All electricity providers in Houston offer a broad selection of plans for different contract lengths. Many also offer month-to-month and prepaid electricity plans. The bottom line is that everyone’s needs are different and all contract term lengths offer advantages and disadvantages.
Energy deregulation has been in place for several years however there are still a lot of people who are confused or who have not fully understand the implications, structure, details and workings of energy deregulation. Many simply know that energy deregulation means people now have the power to choose their electric companies – a diversion from the previous system where a single utility company provides services for the generation, transmission and distribution of electricity.
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).
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.
