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.[117]

Because prices from energy companies in Maryland rise and fall depending on the wholesale price of energy, residents may want a more stable rate for a longer period. A fixed-rate energy plan offers you just that, with a consistent rate for the duration of your agreement at current energy prices – regardless of fluctuations in the energy market. This could mean protection from rate spikes and savings for electric utility customers.
Aside from times of natural disasters and large-scale accidents, electricity prices tend to be steadily dictated by electricity demand. Typically, the price of electricity rises when demand rises. In turn, the lower demand is, the cheaper electricity rates become. This pattern is due to the fact that increased demand requires increased energy production. When extra energy is demanded, utilities are forced to use alternative sources of energy production that may cost more to operate. For example, when electricity demand reaches a high point in Texas, coal plants are used alongside the typical natural gas plants. These coal plants are costlier and less effective than natural gas plants, but are necessary to meet high electricity demand levels.[1]

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.
In Maryland, you have the power to choose your electricity and natural gas suppliers. More than 500,000 Marylanders have already switched energy suppliers. Need a good reason to switch? Some suppliers regularly offer rates and service that are 10% or more cheaper than the utility. Things could get worse - Baltimore Gas and Electric Co. has proposed a rate increase it says would boost the average residential customer's total bill by $5.77 per month. A recent Choose Energy survey found that more than 86 percent say they've never chosen a competitive Maryland electricity plan, meaning they're probably paying more than they have to for energy. Don't pay more. Just enter your ZIP code above to see how you can begin saving with Choose Energy!
Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
