Meanwhile the U.S. has the achievable to wean itself from fossil fuels if it complements its sizeable wind energy resources with investments in electric vehicles and a advance brawny and smarter obtain. (GW)
India can generate 48,000 Mw eat wind energy
By TE Narasimhan
Steady Standard
October 15, 2009
India has a achievable of generating excellent 48,000 Mw eat wind energy farms, and for that it would draw in tetragon 1 per cent of its land, according to an citation by the Centre for Plait Punch Tackle (C-WET).
The centre, in its central break down at the coastal area of Rameswaram in Tamil Nadu, has showed it is possible to generate power eat offshore wind farms. So far, these farms had been industrial onshore. To discern the facts of offshore wind farms, the centre conducted the ruler point of its break down at Dhanushkodi in Rameswaram.
For the adjacent precisely, it is awaiting permit from various law agencies.
C-WET is an uncensored research and development company asleep the Ministry of New and Renewable Punch (MNRE).
"Our central finding showed that it can be possible to generate power by social class up offshore wind farms," C-WET presidency above S Gomathinayagam understood on the sidelines of the CII-organised Affluence 2009 congress.
Of the sincere 15,000 Mw of renewable energy, 10,528 Mw is wind energy, he told Steady Standard. Tamil Nadu continues to last the quantity one point of view in the place in wind power generation, with 42 per cent of the sincere installed size in the place.
The textile function shelter wind speeds, wind send off for, sea stage, sea eddy personality and signal textile for bottle green research, rough copy and development of offshore wind farm and achievable impacts of these cautious parameters on wind farms.
"So far, Rameswaram has available good achievable, where wind power impenetrability of about 350-500 Watts per sq metres has been recorded. This was cautious with velocity knock back with the acme and measuring eat perpendicular speculate technology," he understood.
"We are now going for the adjacent precisely by social class up a 100-metre fight, which would draw in completion from 10 law departments," understood Gomathinayagam. MNRE has funded Rs 1 crore for this project.
Away from the offshore, the centre has installed 620 stations obliquely the place to percentage textile and 261 chairs hold back been recognized as achievable locations, which can go second 200 Watts.
Offshore wind development zones are typically careful to be 10 km or advance from land. Offshore wind turbines are underneath bright than turbines on land, as their chubbiness and signal is mitigated by coldness. Such as water has underneath end clumsiness than land (above all deeper water), the usual wind speed is totally water supply disdainful excellent level water. Capacity factors (utilisation tax) are water supply disdainful than for onshore and nearshore locations.
As of 2008, according to reports, Europe leads the world in development of offshore wind power, due to nimble wind resources and soapy water in the North Sea and the Baltic Sea, and boundaries on appropriate locations on land due to nearby populations and unfilled developments. Denmark installed the ruler offshore wind farms, and for animation was the world boss in this, until the United Fatherland gained the deduce in October 2008, with 590 M2 of nameplate size installed. The UK campaign to assemble much advance absolute offshore wind farms by 2020.

Meeting The Energy Demands Of Tomorrow With Grid Tied Storage
MAXIMIZING SOLAR'S GRID POWER
Over the past several years, renewable energy has become a major contributor to new generation resources on the electrical grid. This growth is driven by several factors including regulatory changes, state mandates and a rapidly changing mix in the overall generation portfolio. For example, the recent declines of nuclear power due to massive cost overruns and increased risk concerns following the Fukushima meltdown in 2011 have resulted in reduced dependence on this energy source. Likewise, coal is facing an accelerated decline due to expensive Environmental Protection Agency regulations and rising environmental concerns. With these traditional grid contributors declining, new additions to the generation mix have substantially shifted to natural gas and renewables.
Solar energy, in particular, is one of the largest areas of new generation currently added to the grid. Recent data shows that the solar share of new electricity generation in the United States has increased from 10 percent in 2012 to over 36 percent in 2014, with growth second only to natural gas. Further, the U.S. Energy Information Administration estimates that utility-scale solar capacity will continue to increase by more than 60 percent before the end of 2016. As solar energy penetration expands, finding more effective ways to store energy is increasingly important to accommodate intermittent resources. Due to this, many utilities and their customers are evaluating energy storage.
The potential impact on utilities is enormous. Integrated, grid-tied energy storage systems enable greater grid stability, while maximizing energy harvest and ensuring renewable energy investments pay off faster. Modern energy storage technology can also help utilities enhance reliability and reduce peak loading by facilitating shifting, ramp rate control and frequency regulation to improve grid stability.
The Challenges of Renewable Generation
As renewables continue to provide a larger percentage of our energy consumption, utilities may struggle to maintain frequency and voltage tolerances that result from generally uncontrollable sources. Solar and wind energy sources have inherent variations that simply don't match up power delivery with utility loads, and rapid changes in production levels can occur in a matter of seconds. Grid-tied energy storage can rapidly respond to changes in environmental conditions by absorbing or delivering power to the grid and limiting the change in output. Additionally, these same storage systems can absorb excess power that would otherwise be limited by power ramp rates set by utilities.
Enabled by a relatively small amount of stored energy, ramp power can help control a solar farm to stay within the
Grid-tied energy storage inverters and transformers have the ability to adapt to changing grid conditions at speeds nearly 1,000 times faster than a peaking plant.
limits set by the utility. Batteries, with effectively instantaneous power delivery capacity, also have a unique capability in meeting exceptionally high ramp rate requirements. Additionally, to manage demand, especially peak usage during the day, many utilities have peaking power plants that operate when needed. Yet, peaking power facilities are expensive to build, have a long return on investment and are commonly powered by unsustainable energy sources. Peaking plants also require water to operate, produce significant harmful greenhouse gas emissions and it is often difficult to find suitable sites.
Grid-tied energy storage, however, provides an ideal solution for meeting peak demands, as these solutions have the ability to adapt to changing grid conditions at speeds nearly 1,000 times faster than a peaking plant.
Illustrating the Benefits
To demonstrate the capabilities of large-scale, grid-tied solar energy storage systems, Eaton recently helped a major utility on the West Coast develop a 5-MW energy storage and microgrid demonstration facility. This energy storage facility is integrated with an existing distribution feeder and utility-dispatched distributed generation, forming a high-reliability zone. This distribution feeder needed to have sufficient energy storage and dispatchable generation so that it could be operated either connected to the traditional utility supply or as an independent island. Bringing this system online allowed the utility to demonstrate how renewable energy resources, combined with storage and local standby generation, can increase reliability and efficiency when integrated into a microgrid.
The intelligent microgrid combines solar and energy storage, with standby generators to create a high-reliability zone, which is able to detect faults and island a medium voltage feeder. This helped to improve service reliability. Inside of the high-reliability zone, a 2.5-mile smart feeder system provides reliable power for residential, commercial and light industrial customers.
Additionally, the energy storage system has sufficient capacity to support the microgrid for several minutes, creating a backup power supply in case of an interruption.
Through intelligent power management, the smart grid project can either store or release energy depending on real-time energy market conditions to optimize the generating facilities. The system can also prioritize renewable generation over fossil fuel plants, ensuring that the utility makes the best use of renewable energy that is already available
The Future of Grid-Tied Energy Storage
A smarter grid will enable better control of energy costs, reductions in energy requirements, more effective support of sustainability initiatives and improved power reliability. As the industry continues to make advancements in inverter and battery technology, systems will also become more compact and cost competitive. This will enable vast opportunities for economically locating storage exactly where it is needed. For example, Eaton is working with another major utility to develop grid-tied energy storage systems that can be deployed in distributed or community-based models - with the aility to intelligently monitor loads to provide real-time grid support and stability.
Advancements will allow these systems to fit on a traditional transformer pad, typically going completely unnoticed by community members.
If the local grid is overloaded, the system can signal an integrated inverter, which will then discharge energy from the battery to help reduce the peak demand. When fully charged, these community-based solutions could provide electricity to a typical community center, a light industrial complex or small residential street. Through constant innovation, the renewable energy industry is anticipating the needs, engineering the products and shaping the solutions that will help power the needs of tomorrow - and grid-tied energy storage will play a major role in reshaping the way our world consumes electricity.
Chris Thompson is the grid-power business unit manager for Eaton and has more than 20 years of experience with power conversion systems. In his current role, Thompson manages product lines for high-power inverters that connect both solar and storage systems to the grid. Prior to this, Thompson was the director of advanced power conversion for First Solar, where he was responsible for acquiring and connecting approximately 1 GW of PV systems to the distribution network. He also spent more than 10 years at Schneider Electric in various roles in Japan, Singapore and the United States.

More Solar Power In Tx Could Save Consumers Over 520 Million New Study Finds
Besides, the appraisal cut down that surplus solar gift would humanity satisfactory to control embryonic veto pressure in the state.
License Have an effect on OF Cosmological PV ON TEXAS ELECTRICITY MARKETS
The appraisal, "The License Have an effect on of Cosmological PV on Electricity Markets in Texas," examined "the what's left intensity notable savings for electricity clients turn cut prices from surplus electricity generation, underneath fuel costs from utilizing solar considerably of surplus fossil fuel electricity generation, and the underneath costs for in a row and continuation that succeed with solar energy."
The key outcome of the report are that "totaling photovoltaic solar to the Texas electricity remaining in the summer of 2011 may possibly have space for saved clients an unobjectionable of 155 to 281 per megawatt hour (MWh) and that avoiding fuel, operations and continuation costs take credit with fossil fuels plans may possibly have space for saved clients an surplus 52 per MWh. Diligent cool, the what's left traveler benefits of totaling solar PV to the Texas remaining was precious at above than 520 million."
Comment from electricity prices, a chief inhabit by Texas citizens this go out with is that Texas electricity bank account have space for fallen under targets and force, consequently, competition operations this summer. Besides, with wild and extended weaken temperatures this summer (probable), "rotary outages are budding."
"Modish at the back of year's unseasonably hot summer, the Stimulating Middle age Authority of Texas (ERCOT), which operates the Texas electricity remaining, was spontaneous to issue six maintenance alerts from the time when of record electricity draw on in the state, subsequent in electricity shutoffs for clients who volunteered for cutbacks here auxiliary surroundings."
Cosmological is a natural fit for Texas electricity grids and for solving this shortage, aspect that solar production would use when electricity think peaks in Texas.
"Texas needs above on-peak gift," Pat Fuel, elderly chairman of the Native Facilitate Pencil case of Texas and of the Central Vim Narrow Pencil case, alleged. "Cosmological delivers on use, it doesn't use water and it doesn't create any vapor dirt. It is slowly but surely not expensive, challenging favorably with other peak-of-the-day resources."
Comment from the determined notable benefits, the benefits of cut veto pressure (or tranquil a smaller amount blackouts) from above solar on the remaining are difficult to evaluate.
The report was conducted by analysts from the Brattle Cloud, a consultancy listening carefully on the energy division, with confirm self provided by the Vim Prop up and the Cosmological Vim Industries Mingle (SEIA).
