Another unwelcome side effect of not knowing your average monthly kWh usage level is that you may end up paying more than you expect. This can occur when a customer inadvertently shops an electric rate based on a higher usage level than they actually use. Electricity suppliers commonly advertise their electric rates associated with the highest (2000 kWh) usage levels since those tend to be the lowest rates.
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. 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.
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.
