Enel Green Power inaugurated two geothermal power plants in Nevada (US), on April 17. The total capacity of the two plants is 65 MW, which is enough to power about 40,000 households, generating some 400 TWh annualy. The plants are also a significant move towards achieving Nevada's energy goal which is to generate 20% of electricity from renewable resources by 2015.

The addition of the new plants, Stillwater and Salt Wells, quadruples the total amount of geothermal electricity produced by Enel Green Power in the US.

Both plants are medium enthalpy plants, which means water pumped from underground is at temperatures between 130 and 150 degrees Celsius. The heat from the heated water is transferred onto a working fluid (in this case isobutane), which in turn powers steam turbine generators. Water is returned underground, and the working fluid remains in the closed loop process, eliminating the possilibility of leaking into the environment. Additional benefits of these two plants come to the local community, in form of 25 permanent jobs, after having created more than 300 temporary jobs during construction earlier.

Enel Green Power also has installations in Italy (Tuscany, about 700 MW), but also in South and Central America (Chile, El Salvador).


Iberdrola Renewables opens Peñascal wind farm in Texas

April 21st, 2009 | Posted in Wind

iberdrola1The new wind farm developed by Iberdrola Renewables has 202 MW of installed capacity, which is enough to power about 70,000 households. One of the features of the new wind farm is also a radar detector which alerts operators of incoming large flocks of migratory birds, something that  has been identified as a problem with wind farms (huge wind turbines in the birds' flight path pose a threat to the birds). More than 4000 hours have been spent in studying the migratory habits of birds in the area, to ensure wind farm construction and operations wouldn't harm the birds. If a bird flock is detected, the operators are warned in advance, so wind turbines are stopped on time to allow the birds to pass without being harmed.

The farm is located in Kennedy County, Texas. The total 202 MW come from 84 wind turbines. The company has signed agreements to sell the produced energy over the next fifteen years with CPS Energy of San Antonio and South Texas Energy Cooperative. As part of local community support, Iberdrola has signed lont-term agreements with a school in the area, the Sarita Elementary School, to support its new science lab.

Iberdrola Renewables installed more than 3 GW of wind power capacity in the US, which makes this wind power market very important for the company.

Report on reliable integration of large-scale wind and solar into the electric grid

April 18th, 2009 | Posted in General

nerc_logoOne of the major obstacles for introducing renewable energy power to general consumers is the problems that come with electric grid integration, due to the specific regime in which renewable energy sources can be exploited (intermittance, energy storage). The latest NERC (North American Energy Reliability Corporation) report says large-scale renewable energy will require a different approach in the way the power system is planned and operated. The report "Accommodating High Levels of Variable Generation" was released on April 16, and highlights transmission additions, reinforcements, better forecasting of variable generation output, and access to flexible grid resources. These have been identified as key contributors for reliably integrating variable power resources into the electric grid.

With a significant amount of wind energy coming to the market, as well as the future expected growth of solar power, this report comes at the right time to push things forward. Much research is going to have to be done, for example on technical issues like power flow and stability modeling, but also consistent and reliable forecasting of variable resource availability.

If you want more specifics, see a more detailed outline of the report, as well as some specific recommendations.

BP Wind Energy and Dominion announced that phase one of the Fowler Ridge Wind Farm in Benton County, Indiana, is now fully operational. This means Indiana just got an additional 400 MW of clean renewable energy, enough to power about 120,000 households. BP and Dominion are partners for a portion of about 300 MW of the total installed capacity so far. The two companies could increase the total installed capacity to about 750 MW in the future.

Construction of Phase 1 began back in 2008, and utilizes 182 Vestas 1.65 MW wind turbines and 40 Clipper 2.5 MW turbines. BP Wind Energy is the facility operator.

This project, and the Meadow Lake Wind Farm project bring a total of about 600 MW of active wind power capacity at the present time. Since both projects have additional phases, Indiana could be looking at an additional 950 MW of wind power in the future (350 from Fowler Ridge and 600 the Meadow Lake).

Grays Harbor Ocean Energy Co has obtained a US federal preliminary permit for a demonstration project which uses a combination of wave and wind power generation. Basically, wind turbines harness wind energy from above the ocean's surface, while wave power generators, as part of the same facility, harness energy from waves, below the ocean's surface. The company has also obtained preliminary permits for seven sites in six US states. Each site has about 100 square miles in area, and is capable of generating 1 GW. The sites are located in California, Hawaii, Massachusetts, Rhode Island, New York and New Jersey. Even though the permits are for wave power only, the platforms that will hold the wave power generators, can also support wind turbines. Grays Harbor Ocean Energy hopes these new projects will bring clean renewable wave and wind energy to coastal communities, as well as jobs.

We may be seeing one of these installations near San Francisco and near Ventura County. The location near San Francisco is rumored to be somewhere in between the Golden Gate and Farallon Island, in the middle of a marine sanctuary (which is bound to raise a few concerns).

First Solar Inc is going to develop a 48 MW photovoltaic power plant for Sempra Generation, a solar power plant operator. The new power plant is going to be located some 40 miles southeast of Las Vegas, Nevada. Together with another 10 MW solar power plant already completed by First Solar in 2008, also for Sempra, the total installed solar power capacity of 58 MW will be the largest single PV power plant in North America. Both the existing and the new power plants will lie adjacent to the existing Sempra El Dorado Energy 480 MW power plant.

According to John Carrington, First Solar's executive vice-president, the company is pleased to have been chosen for such a large-scale solar power project, stating that this is proof that First Solar has the ability to provide a cost-effective energy solution for utility-scale projects.

Horizon Wind Energy officially breaks ground for the Meadow Lake Wind Farm

April 15th, 2009 | Posted in Wind

The Meadow Lake Wind Farm represents an important project in Indiana's initiative for increasing installed renewable energy capacity. Located in the northwestern part of Indiana, the farm will stretch across the White and Benton Counties. Indiana has a significant wind power potential, and the chosen location has many benefits, for example electrical energy transport access, and proximity to power markets. Phase I of the Meadow Lake project will see some 200 MW of wind power capacity installed. Phase II is actually quite larger, potentially bringing an additional 800 MW of installed wind power capacity to the states renewable energy total.

Meadow Lake Wind Farm will bring some 400 temporary jobs, and 20 permanent jobs once the project becomes operational. Wind turbines used for the project will be 121 Vestas V82 1.65 MW units. Horizon Wind Energy, the wind farm developer and operator, is owned by EDP Renewables, one of the largest wind power operators in the world, with more than 2.5 GW of installed wind power capacity.

In total, that's about 1 GW of wind power installed in Indiana in the "near" future, which is great news for the region.

AWEA released the 2009 wind energy industry report

April 14th, 2009 | Posted in Wind

American Wind Energy Association (AWEA) released its latest report on the wind industry in the US.

Wind energy leaders have kept their top positions, while other leaders have emerged in different categories. Twenty four states have had new wind turbine manufacturing facilities opened, expanded or announced during 2008.

A quite interesting conclusion from the report is that Texas is the state with largest wind energy capacity installed – 7.2 GW, while Minnesota (1.75 GW) and Iowa (2.8 GW) generate about 7% of total energy needs from wind power. Indiana is the state with the fastest growth in wind power, percentage wise.

AWEA CEO Denise Bode said the wind energy industry today generates not only clean energy for the US economy, but also hope for American workers and businesses. She went on to say that no matter what part of the wind industry we look at, manufacturing or maintenance, people are employed in the wind power almost in all 50 states today.

The overall goal is to produce 25% of electricity needs from renewable sources by the year 2025. The US is going to have to make long-term investments in billions of dollars in clean energy installations and manufacturing facilities, creating hundreds of thousands of jobs.

Major project owners are NextEra Energy Resources, Iberdrola Renewables, MidAmerican Energy and Horizon-Energia de Portugal. Interestingly enough, about 43% of wind turbines installed come from GE Energy, while the rest come from other major wind turbine manufacturers – Vestas, Suzlon, Gamesa, but also from some newer companies – Acciona, REpower (now owned by Suzlon), Fuhrlander, DeWind and AWE, all whom entered the US market in 2008.

More than 25 GW of installed wind power will generate about 73 TWh in 2009, which should ne enough to power some 7 million average US households.

The report, with all the detailed information, is available on the AWEA website.

Update: you may want to take a look at AWEA's Windpower Outlook 2009 report as well. It features great charts illustrating wind power growth in the US, as well as other benefits of renewable energy over traditional energy sources.

Midwest green transmission superhighway has been granted incentives by FERC

April 13th, 2009 | Posted in Wind

itclogo

Federal Energy Regulatory Commission (FERC) has given its approval for the infrastructure investment rate incentives for a 3000-mile regional "green power superhighway" proposal. The new transmission infrastructure is aimed at transporting electricity generated by wind power from the upper Midwest to consumers in Chicago, Minneapolis and other centers.

Green Power Express LP (ITC Holdings) designed the project for the benefit of customers who are going to use energy coming from remote renewable energy locations through high voltage transmission lines. This kind of project requires effective transmission planning that goes way beyond the needs of a single utility or local region, according to ITC.

One of the major obstacles for connecting consumers with renewable energy sources, is the transmission infrastructure that has been thus far tailored to accommodate the needs of traditional power sources, such as fossil fuel power plants. In order to move towards more renewable energy derived electricty, a new transmission infrastructure needs to be built. Similar projects have been announced in Europe, especially in Great Britain, where a major renewable energy electricity transmission line is going to be built between Ireland and the UK.

Green Power Express has estimated the costs for the 765 kW transmission network to be between US$ 10 billion and US$ 12 billion. The network will eventually span across seven states and delivery up to 12 GW of wind energy and stored energy from the Dakotas, Minnesota and Iowa, to Midwestern load center in Chicago, Minneapolis and southeastern Wisconsin.

If anyone has been having doubts about the expansion of renewable energy, at least on the North American continent, this should be enough of a reassurance that renewable energy is coming to the mainstream consumers, and with serious figures.

Wind energy brings winds of hope to Detroit

April 11th, 2009 | Posted in Wind

The motor industry capital of the world has seen some hard times lately. Many have been left unemployed, and more trouble is on the way, as the motor industry in the US is sinking further. The wind energy industry, even though currently slowed down by a combination of recession effects and delays in government funding, brings a little hope to the unemployment troubled Detroit area. One wind turbine manufacturer has decided to move things along. Global Wind Systems has decided to hire 250 new employees to work for the company's latest venture, a new wind turbine assembly plant in Novi, Michigan, some thirty miles away from Detroit.

In December last year, Global Wind Systems received about US$ 7 million in tax credits, to create additional 256 jobs over six years. Global Wind systems hopes to double that number in the next two years.

Other companies may find the Detroit area interesting for hiring workforce – these are all individuals who are well versed in manufacturing process, having worked for the motor companies in the past years. In fact, most applicants for job positions in the new wind turbine manufacturing facility listed automotive industry work experience. With the expected boom for the renewable energy industry, wind energy in particular, there is realistic hope for employment for everyone in the area.
