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.
You betcha! Most Texas electricity suppliers offer plans that include a percentage of energy sourced from renewable resources, such as hydro power, wind power and solar power. Some are totally sourced that way. These plans are a great way for Texas energy customers to help the environment without breaking the bank. In addition to green energy plans, many Texas suppliers give customers the option to purchase renewable energy certificates, or RECs, that further offset customers’ carbon emissions. The purchase of RECs also helps fund research and usage of renewable energy sources, so that Texas can stay at the forefront of eco-friendly power technology.
ElectricityPlans lets you easily compare electricity plans by displaying all-inclusive rates at all advertised usage levels in a simple easy-to-read format. You can easily estimate your actual all-in electric bill at any given usage level using our Plan Details and Pricing section for each plan. All energy charges, delivery fees, bill credits, and other fees for each plan are shown so you can accurately estimate your monthly electric bill. By showing all rates and fees, you’ll avoid the electric bill sticker shock and so-called “teaser rates” commonly used by electric suppliers to achieve better search results on sites such as powertochoose.org.
A lot of these financial structures ultimately boil down to being a form of government guarantee, which means that they can’t be scaled up to “solve” countries’ power problems because the governments cannot carry all the liabilities. Countries try to introduce the private sector into power generation precisely to reduce such guarantees, which then end up returning through the back door in the form of government support.
Excessive Total Harmonic Distortions (THD) and not unity Power Factor (PF) is costly at every level of the electricity market. Cost of PF and THD impact is difficult to estimate, but both can potentially cause heat, vibrations, malfunctioning and even meltdowns. Power factor is the ratio of real to apparent power in a power system. Drawing more current results in a lower power factor. Larger currents require costlier infrastructure to minimize power loss, so consumers with low power factors get charged a higher electricity rate by their utility. True power factor is made of displacement power factor and THD. Power quality is typically monitored at the transmission level. A spectrum of compensation devices mitigate bad outcomes, but improvements can be achieved only with real-time correction devices (old style switching type, modern low-speed DSP driven and near real-time). Most modern devices reduce problems, while maintaining return on investment and significant reduction of ground currents. Power quality problems can cause erroneous responses from many kinds of analog and digital equipment, where the response could be unpredictable.
It’s very important to do your own research to understand the business focus of the company you are considering, as well as tax advantages (and possible disadvantages) if the company is a limited partnership. For example, Seadrill Ltd. SDRL, -1.72% provides offshore-drilling services worldwide. Seadrill Partners LLC SDLP, -3.22% operates offshore-drilling rigs under specific contracts with several major oil companies, including Exxon Mobil Corp. XOM, +0.17% and Chevron Corp. CVX, -0.43%
The local electric company is the utility – that’s the company who owns the infrastructure, including the poles and power lines that deliver electricity to your home. They are who you call if your power goes out or there's an emergency. But in almost every city in Texas, you must choose another company to supply that energy, called a Retail Electric Provider (REP). These REPs, like Spark Energy, allow you to choose electricity plans that offer competitive prices and plans to meet your needs.
