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.
The inclusion of renewable energy distributed generation and AMI in the modern electricity grid has introduced many alternative rate structures. Simple (or fixed) rate, tiered (or step) rate, TOU, demand rates, tiered within TOU, seasonal, and weekend/holiday rates are among the few residential rate structures offered by modern utilities. The simple rate charges a specific dollar per kilowatt ($/kWh) consumed. The tiered rate is one of the more common residential rate programs, and it charges a higher rate as customer usage increases. TOU and demand rates are structured to help maintain/control a utility’s peak demand. The concept at its core is to discourage customers from contributing to peak-load times by charging them more money to use power at that time.
At Quick Electricity, we’ve outlined the best Texas electricity plans ranging from one month to two years. No deposit electricity plans are great for people who are constantly moving, college students, renters, or those who want to try an electric company before locking themselves into a fixed rate energy plan. Long-term plans are for people who want to lock in a low rate, and not have to worry about fluctuations in that rate for quite a while.
OPEC nations, along with Russia and Mexico, have refused to cut production, which is their traditional tool to prop up oil prices, out of fear of losing market share to the U.S., which has transformed the international oil market by greatly expanding hydraulic fracturing over the past decade. And U.S. producers might not lower production as quickly as some investors expect because of the significant improvement in the efficiency of horizontal fracturing wells.
