ITRON and Clean Power Research are embarking on the next phase of research that will lead to high-fidelity distributed solar photovoltaic (PV) forecasts, and integration of those forecasts into net load forecasts for the California Independent System Operator (ISO). Increasing forecast accuracy and improving net load forecasts will help reduce solar integration costs within the State of California.
The project, "Improving Solar and Load Forecasts: Reducing the Operational Uncertainty behind the Duck Chart," is being funded by an Electric Program Investment Charge (EPIC) award from the California Energy Commission. The EPIC grant "Advancing Utility-Scale Clean Energy Generation" (PON-13-303) was made available to fund applied research and development projects to improve utility-scale renewable energy generation. Set to kick-off this month, the project will further advance work completed as the result of a CALIFORNIA SOLAR INITIATIVE (CSI) RESEARCH, DEVELOPMENT AND DEPLOYMENT (RD&D) 3 GRANT to support integration of behind-the-meter solar forecasting to the California ISO load forecast.
As a project partner to Itron, Clean Power Research will be using a combination of research and software approaches to support Itron's development of an integrated load forecast. The forecast will include all solar generators within the State of California, including residential, commercial and utility-scale PV systems. By linking solar forecasts to net loads in an operational environment (which is unlike anything currently available), it will be possible to maximize the benefits of solar generation on California's electric grid.
Advancements will include:
* Irradiance forecast accuracy improvements using probabilistic and short-term prediction methods.
* PV fleet power forecasting improvements that account for system degradation and outages.
* Integration of solar forecasts into Itron's net load forecasting tools for the California ISO.
* Application of these tools to improve solar integration to the grid.
RELIABLY INTEGRATING A GROWING GENERATION RESOURCE
California is on the way to procuring a minimum of 33% of the state's electricity supplies from renewable resources, and under Governor Brown, may EXPAND THE STATE'S RENEWABLE ENERGY GOALS TO 50%. Most of these renewable resources will come from utility-scale PV systems and PV located on the customer-side (i.e. rooftop or premises) of the meter. Customer-side PV systems are typically "behind-the-meter," which means the utility does not have access to PV production information at that site, only net energy use.
As PV capacity continues to increase, as shown in Figure 1, the operational and economic issues associated with the intermittent nature of PV become much more significant. In 2013, the California ISO introduced the concept of a "DUCK CHART," which shows the potential impacts of increasing levels of PV capacity on the California ISO distribution system.
As illustrated in Figure 2, this includes the potential for over-generation as the sun reaches its zenith, and sharper peak loads later in the day when solar generation has waned. This uncertainty increases the need for the California ISO to quickly adopt new technologies that can balance electricity supply capacity.
With this project, Itron and Clean Power Research are taking targeted steps to reduce solar integration costs by improving the accuracy and effectiveness of solar and load forecasting. As the solar capacity leader in the U.S., California will face challenges maintaining reliable grid operations without suitable solutions to mitigate solar variability. This EPIC project will enable Itron and Clean Power Research to reliably and cost-effectively take California into the high-penetration PV era.
Alternative energy is an umbrella term that refers to any source of functional energy intended to change fuel sources without the undesirable effects of the changed fuels. The term "alternative" presupposes a set of unfavorable energy innovations versus which "alternative energies" are contrasted. The list of energy innovations left out is an indicator of which issues the option technologies are meant to address. Debates concerning dominant sources of energy and their alternatives have a long history. The nature of what was concerned alternative energy sources has changed significantly with time, and today, because of the range of energy selections and differing objectives of their advocates, specifying some energy types as "alternative" is extremely controversial. In a basic sense in modern society, alternative energy is that which is produced without the unfavorable repercussions of the burning of fossil fuels, such as high carbon dioxide emissions, which is thought about to be the major contributing aspect of global warming according to the Intergovernmental Panel on Climate Change. Sometimes, this less comprehensive meaning of"alternative energy" excludes nuclear energy (e.g. as defined in the Michigan Next Energy Authority Act of 2002). Generate your own energy. Generating your own energy can be good for the environment and great for your pocket too. Low-carbon technologies such as wind turbines, solar panels and wood fuel boilers use renewable sources of energy, so you use less nonrenewable fuel source, which reduces your carbon footprint in addition to your fuel expenses. Exactly what's more, with government financial incentives available, it's never ever been a better time to set up. Find out more now! There are many reasons we are looking towards alternative energy sources. With many.countries, and US cities, signing the Kyoto Treaty, efforts to minimize toxins and greenhouse gases are a primary focus in today's culture. Alternative, or renewable resource, sources show substantial promise in assisting to decrease the amount of contaminants that are by-products of energy use. Not only do they safeguard versus unsafe by-products, but utilizing alternative energy assists to preserve many of the natural deposits that we currently utilize as sources of energy. To comprehend how alternative energy use can help protect the delicate ecological balance of the world, and help us conserve the non-renewable energy sources like fossil fuels, it is important to know what kinds of alternative energy is out there. Wind Power. Wind energy harnesses the power of the wind to propel the blades of wind turbines. The rotation of turbine blades is converted into electrical current by methods of an electrical generator. In the older windmills, wind energy was used to turn mechanical machinery to do physical work, like crushing grain or pumping water. Wind towers are usually built together on wind farms. Now, electrical currents are harnessed by large scale wind farms that are used by national electrical grids as well as small individual turbines used for providing electricity to isolated locations or individual homes. In 2005, worldwide capacity of wind-powered generators was 58,982 megawatts, their production making up less than 1 of world-wide electricity use. Pros. Wind power produces no pollution that can contaminate the environment, Since no chemical processes take place, like in the burning of fossil fuels, in wind power generation, there are no harmful by-products left over. Since wind generation is a renewable source of energy, we will never lack it.Farming and grazing can still take location on land occupied by wind turbines which can help in the production of biofuels. Wind farms can be built off-shore. Cons. Wind power is intermittent. Consistent wind is needed for continuous power generation. The turbine remains and less electricity is produced if wind speed decreases. Large wind farms can have a negative effect on the scenery. Wind power produces no pollution that can contaminate the environment, Since no chemical processes happen, like in the burning of nonrenewable fuel sources, in wind power generation, there are no harmful by-products left over. Because wind generation is a renewable source of energy, we will certainly never run out of it.Farming and grazing can still take place on land occupied by wind turbines which can help in the production of biofuels. Wind farms can be built off-shore. Solar Power. Solar energy is used commonly for heating, cooking, the production of electricity, and even in the desalination of seawater. solar power works by trapping the sun's rays into solar cells where this sunlight is then converted into electricity. Additionally, solar power uses sunshine that hits solar thermal panels to transform sunshine to heat water or air. Other methods include making use of sunlight that attacks parabolic mirrors to warm water (producing steam), or simply opening a rooms blinds or window shades to allow entering sunshine to passively heat a room. Pros. Solar power is a renewable resource. As long as the Sun exists, its energy will reach Earth. Solar power generation releases no water or air pollution, because there is no chemical reaction from the combustion of fuels. Solar energy can be used extremely efficiently for practical uses such as heating and lighting. The advantages of solar power are seen frequently to heat pools, health clubs, and water tanks all over. Cons. Solar energy does not produce energy if the sun is not shining. Nighttime and cloudy days seriously limit the amount of energy produced. Solar power stations can be very expensive to build. Geothermal Energy. Literally, geothermal ways, "earth heat." Geothermal energy harnesses the heat energy present underneath the Earth. Hot rocks under the ground heat water to produce steam. When holes are drilled in the region, the steam that shoots up is cleansed and is used to drive turbines, which power electric generators. Pros. Geothermal energy produces no hazardous by-products if done correctly. Once a geothermal plant is build, it is generally self-dependent energy wise. Geothermal power plants are normally small and have little effect on the natural landscape. Cons. If done incorrectly, geothermal energy can produce toxins. Improper drilling into the earth can launch harmful minerals and gases. Geothermal sites are susceptible to running out of steam.

The parties in the negotiations to bring wind power to Delaware told the Public Service Commission (PSC) this afternoon that they are making progress and hope to have agreement on the terms by September 14. While the parties did not meet the PSC's original target of reaching agreement in sixty days, Hamermesh and representatives of the parties did report progress, and all agreed to the deadline of September 14.
Mediator Lawrence Hamermesh presented the first detailed report on the negotiations since the PSC ordered the parties to the table in May. He reported that Delmarva Power and Bluewater Wind have resolved some issues, including the term of the proposed contract, the use of renewable energy credits and remedies in case of contract default, for instance if permits are not obtained. The biggest issues such as plant capacity and pricing have not yet been resolved.
Delmarva Power (DPL) is simultaneously negotiating with NRG and Conectiv Energy for a natural gas backup facility near the wind farm. The negotiations are expected to produce term sheets - detailed descriptions of the proposed contracts - for presentation to the PSC by September 14. While Delmarva Power is negotiating with all three bidders, the substantive terms for the backup power plant will depend on the terms for the wind farm. The term sheets are expected to be as long as twenty pages each. Todd Whitman, speaking for DPL, emphasized the magnitude of the potential deal, which he said could total as much as 10 billion over 25 years.
All of the parties spoke of the complexity of the negotiations, the operative metaphor being a Rubik's Cube (a metaphor reported here last month). DPL is negotiating with Bluewater Wind, and with two companies to provide backup power. Bluewater Wind already has a long term agreement with the Delaware Municipal Energy Corporation (DEMEC). The terms of these agreements must comport with rules for producing and moving electricity set forth by PJM Interconnection, which manages the regional power grid. The federal review of the wind farm site itself is somewhat fluid, since the Mineral Management Service, which oversees the leasing of offshore oil and gas fields, has never actually been presented with a proposed offshore wind farm. Other federal agencies will have to review the proposal as well.
Assuming the parties agree, three separate term sheets will be presented to the PSC on September 14 for staff review. The PSC would then review the staff report by October 29. Public comment would be accepted up to November 12, and the PSC and other agencies involved in the RFP would consider the proposed terms, including which of the two backup proposals to accept, on November 20. In the meanwhile, the parties will have been working on turning the terms sheets into complete Power Purchase Agreements (PPAs), which could run as many as 200 pages.
What of the threats of legal action by Delmarva Power and Conectiv Energy (both part of Pepco Holdings)? The PSC adopted Order No. 7246 which denied Conectiv's appeal of the PSC's May decision in no uncertain terms. Conectiv argued that it should be allowed to submit its own wind power proposal. As for DPL's appeal to Superior Court, that has been set aside for the time being, pending the outcome of the negotiations. It doesn't require high levels of paranoia to imagine that DPL and Conectiv have their legal staffs working on further legal actions if the negotiations fizzle.
This is more progress than I expected. To have all parties agree on a deadline is encouraging. But the most significant issues have yet to be resolved. PSC chair Arnetta McRae several times alluded to the intense public interest in the outcome of this process. Just as this public attention affected the decision to opt for wind power, it can only help to keep the process on track. Stay tuned.

The U.S. Topic of Dynamism (DOE) gave two grants totaling 1 million to Lockheed Martin to come to a decision the venture of harnessing energy outward appearance with the hot and unsuspecting bad skin of mass to shoulder electricity on a large scale commercial align.
Diverse preceding deep-sea energy grants which carry to begin with focused on harnessing tidal surf and currents, Lockheed's research command be based on thermal variances as an energy source of their own, referred to as Marine Thermal Dynamism Coins Gear (OETC).
Lockheed Martin's hoop of scientists and engineers command use half of the center time-honored to develop OETC software and paraphernalia that certificate them to smartly believe to be these thermal areas of the deep-sea and just tally them for their assure as renewable-energy sources.
The minute accede living thing explicit to Lockheed command be spartanly for their economic hoop who command be putting tied a economic box of law estimates based on their research on these hot and unsuspecting deep-sea bad skin. Lockheed Martin command need to come to a decision the scalability, law, behavior, and max out assure for large-scale use and commercialization of OTEC technology, all to be included in the box.
An OTEC system uses the passion difference with solar-warmed be drawn against wash and unsuspecting, persuasive wash to run a kindness organization, which produces electricity. Like the sun continually warms the planet's mass, this technology possibly will serve as an equitable, clean, renewable source of energy.
This 1 million is only the contemporary in a around of grants living thing awarded to the organization. It was awarded 8.12 million wait appointment by the Topic of Task to develop OTEC system components and an OTEC pain plow.
Swab energy initiatives endure to originate inclination for concede order the federal declare as the need for environmentally compelling practices becomes added emergence. Person in command Barack Obama in recent times accepted the DOE financial system for the 2011 financial appointment in which they command jump at 28.4 billion, plus 2.36 billion for the DOE Post of Dynamism Effortlessness and Renewable Dynamism (EERE).
Using less of what is needed to run your homestead may be much easier than you think. With a few simple changes you can save money and reduce your impact on the world. The article below will give you some ideas and suggestions that will help you get started to becoming a greener consumer. You can make a difference and save energy simply by taking steps to use less energy every day. If you have appliances that are not in use, keep them unplugged until you need them. Turn off lights and the television when you are finished using them. This simple suggestion helps cut your electricity bills. Do you or your family own a farm? If you do, or if you are aware of someone that does, you may be able to rent some of the property to a local energy company that will install a type of wind turbine. You will benefit from the wind turbine's free energy and it will take up minimal space. When you can, wash your laundry in cold water. The majority of energy use from washing clothes is in the heating of the water. If your detergent is decent, cold water will be as effective as hot when cleaning your laundry. Don't forget to only wash clothes when you have a full load s you are as efficient with your energy as possible! Know the available energy options in your community. Be sure to look at the legislation and incentives available for using green utilities. You might find that you could save money by switching from an electric furnace to a natural gas one, for instance, or from using municipal water to your own well water. Solar energy can heat water for a lesser cost. Purchase a solar water heating system. You have a choice between both an indirect or direct circulation system. The indirect one is your best option if you have to worry about frozen pipes in the winter. Keep your refrigerator well maintained. Your fridge consumes a ton of energy, so make sure it's in good shape. Clean heating coils regularly to get rid of dust. Also, make sure that the seal around the door is clean and tight. Seek out local and federal rebates offered for making energy upgrades to your home. In some cases, the local utility company will offer rebates for the cost of the upgrades. Also look into tax deductions offered by the government that may apply to your green energy technology. All of these rebates will add up, potentially covering the cost of your renovation! If you are apprehensive about what green changes to make to your home, there are many green energy consultants available today. They can tell you if your appliances are running efficiently, and if there are changes you can make. They may also be able to offer estimates as to what it would cost to replace or upgrade your existing systems. Write a reminder to remain on top of goals for energy efficiency, and check each bill against last year to see if improvements were made. The more aware you are of using energy, the easier it is to reduce your energy use. For example, making a decision to reduce electricity usage will help you develop a habit to turn off lights and appliances when not in use. Try using LED lights as opposed to conventional ones for the next holiday season. A US study shows Department of Energy stated that Americans could collectively reduce their energy consumption by over 2 billion kW/h if they all changed over to LED lights. To put this in perspective, that amount of power could supply the energy needs of 200000 homes for a whole year. You could reduce the amount of your own utility bill as well. A home heating alternative to be considered is biofuel. This type of fuel is usually made with a combination of animal fat, vegetable oil and wood. Propane furnace mechanics can adjust your furnace so that you can use biofuels in it. Up to 99% can be biodiesel. Always consult with professionals prior to using this type of fuel in the home. If you really want to take a bit out of your fuel consumption, try making more extensive use of carpools, even to destinations other than the office. IF you've got kids, create a carpool system with other parents in the neighborhood. Those who live close to friends or family can go grocery shopping together. Is your boiler over 10 years old? Buy a new one to save money! A lot of the old boilers weren't constructed with energy saving in mind, as opposed to the newer ones which are much more energy efficient. They produce much less carbon dioxide that benefits you, and they cut down on energy costs. Replace any old major appliances with new Energy Star rated appliances. If you buy an Energy Star-rated appliance, it is guaranteed to use far less energy than the one it replaced. Refrigerators and freezers that are Energy Star rated uses approximately twenty percent less energy. While dishwashers and washing machines can save up to fifty percent on energy bills. Do not forget the most basic ways to save energy, such as turning off the lights you don't need. You might be amazed at the amount of energy savings you can gain over time, simply by making it a point to turn off lights. You also will be saving money when it comes to your power bill. Use some of the information you read in the preceding paragraphs to make your household a greener one. You'll see your energy bills drop and be proud of the service you are performing for the environment. Work on it a little at a time, and you will find that you have a greener home in no time.
DES MOINES, TEMPE & PRINCETON, USA: NRG Energy Inc. and MidAmerican Renewables LLC announced that their 290-megawattAC Agua Caliente solar project has earned two top solar project awards.
The Yuma Area, Ariz., photovoltaic power project animation built by First Planetary Inc., was named Planetary Guard of the Engagement by Renewable Energy Formation, a principal company reconsideration, and PV Guard of the Engagement by Planetary Market leadership Time USA, the industry's principal utility-scale solar power convention. The to start with 30-megawatt facet of the project began commercial consume in January.
"The editors of the Renewable Energy Formation linkage feel strongly that Agua Caliente represents the coaching that solar power is plunder in North America," thought failure to notice editor Jennifer Runyon. "International solar power life-force clue this territory cross its renewable energy goals. For this infer, we were cheerful to depression Agua Caliente Planetary Guard of the Engagement in our 2012 Thinness in Renewable Energy Put heads together program."
"Agua Caliente is a shining example of how choosing the epileptic fit adjust, selecting the belief technology, and assembling a world-class circle is vital for the shot of any solar project," thought Tom Doyle, CEO and beginning, NRG Planetary. "This project is a memorial to the shot of the US Government department of Energy development bankroll program in putting Americans spike to improve. Right now, greater than 400 belabor are council house the biggest solar project in the obtain of Arizona."
"Agua Caliente is an diaphanous project. This pomp thankfulness further demonstrates the viability of solar as an from top to toe renewable energy resource," thought Bill Fehrman, beginning, MidAmerican Renewables.
The Agua Caliente project is ecological to be the world's biggest operational PV power propagate upon cessation in 2014. When absolutely operational, the project life-force cause somebody to tolerable clean solar electricity to surrender the requirements of in the region of 100,000 middle-of-the-road US homes.
