The World Bank and the Technical University of Denmark today launched new Global Wind Atlas, a free web-based tool to help policymakers and investors identify promising areas for wind power generation, virtually anywhere in the world.

The Global Wind Atlas is expected to help governments save millions of dollars by avoiding the need for early-stage, national-level wind mapping. It will also provide commercial developers with an easily accessible platform to compare resource potential between areas in one region or across countries.

The product is targeted at owners of 1.5MW windturbines that use an open-loop water-glycol based IGBT cooling system.  Warm atmospheric  temperatures - lead to water evaporation from the open-loop coolant mix.  The system has to be regularly monitored and serviced  for replenishing and rebalancing of fluid, resulting in costly wind turbine and transformer power down. In addition, when the system is not promptly serviced, the resulting mix imbalance inhibits the cooling properties of the fluid and can potentially compromise the IGBTs, sometimes requiring their replacement. Parker's custom designed KleenVent solution helps optimize wind turbines operation and eliminate maintenance downtime previously required to restore cooling fluid mix levels, by closing the loop on the "open loop" cooling system.   KleenVent effectively eliminates water evaporation by containing the water vapor in a closed loop add-on system, and condensing it back into a liquid to maintain a constant water-glycol ratio maintenance to optimize the cooling systems efficiencies.

Cost savings of KleenVent implementation in 1.5 MW wind turbines with open loop cooling systems

As owners and operators are spending budgets and time maintaining IGBT coolant levels in open-atmosphere cooling systems, the overall cost of maintenance, replacement fluids and reduced reliability adds up quickly. The results of implementing the KleenVent solution, are reduced monitoring and improved turbine uptime and reliability – which net higher productivity and uninterrupted power generation and revenue streams.

Return on investment for the KV-CEI can be measured in as little as a  few short weeks in warmer climates and at elevated operating temperatures, meaning a quick investment in the Parker KleenVent solution can provide breakeven expenditures by summer’s end, along with continued productivity savings for the life of the turbine.

KleenVent KV-CEI technology  -- how the product works

The KleenVent KV-CEI is part of a larger family of products designed to isolate hydraulic systems from airborne contaminants, dust, chemicals and water vapor evaporation. The KV-CEI enclosure solution works by closing off the coolant loop system from the outside atmosphere with a breather bladder. This bladder allows the outside air to inflate and deflate the bladder as fluid levels inside the isolation tank expand and contract due to system liquid temperature changes. A low-pressure relief valve helps prevent system over-pressurization in case of unforeseen air trapped inside the fluid lines, and an open-close air exhausting valve allows the system to be drained and refilled quickly with the proper fluid levels during a normal preventative maintenance cycle. The current KV-CEI design is versatile enough to allow the addition of low-level liquid sensors when needed. We also can design many mounting options designed to fit a particular mounting pattern.  Currently the KV-CEI technology is deployed in wind turbine systems for one of the world's leading wind turbine manufacturers.

The new Parker KV-CEI reservoir bladder barrier creates a closed atmosphere that expands and contracts with temperature- and atmospheric pressure-induced changes. Isolating the internal volume of the reservoir from the existing outside atmosphere prevents both evaporation of water from and the ingress of airborne contaminants into the water-glycol solution. A check valve provides over pressure protection, and a visual level indicator allows local confirmation of the coolant level. An additional port is included to accommodate an optional, industry-standard, liquid-level float switch for remote low-level coolant indication.

Recharge news

Argentina seems to be doing everything right. First the 2015 cross-party revision of the renewables law, then the 2016 RenovAr tender programme – which resulted in huge over-subscription and declining prices – and now global OEMs are announcing local production.

Vestas was the first to announce a nacelle and hub assembly plant. This week, Nordex Group confirmed similar plans. Under the radar, the government’s news service Telám is reporting that Siemens Gamesa is considering a plant in the Bahia Blanca port region, while Recharge has learned that China’s Goldwind has at least studied the local siting of a facility in Mendoza.

Until two years ago, Argentina was the ugly duckling of renewables in Latin America – a country with huge, 200GW-plus wind potential and high, Atacama-level solar irradiation, but one that got just 2% of its power from non-hydro renewables and with no future prospects because of a lack of policies.

Brazil, Chile, Mexico and even its tiny neighbour Uruguay were light years ahead.

Now not even its globally frowned-upon local content rules seem to cloud the sky. Even if those rules are a complex tax-benefit system, giving developers advantages if they buy turbines assembled locally with a minimum content level of 35% by 2020.

Behind this specific stimulus is the expectation that Argentina will manage to continue on the path to reach its legislated target of 20% non-hydro renewable energy supply by 2025, which the government says will require 10GW of new capacity, mostly solar and wind.

This month marks the two-year anniversary of the Department of Energy’s Wind Vision report that quantifies the economic, environmental and social benefits of a wind energy future, if U.S. wind power supplied up to 35% of the nation’s electrical demand by 2050. The Wind Vision outlines a roadmap for growing the wind industry that could support more than 600,000 jobs in manufacturing, installation, maintenance and supporting services.

Here are some examples of the progress we’ve made toward this roadmap in just two short years.


The Department of Energy supports a host of projects that reduce wind energy costs through technology advancements. One area focuses on improving wind resource characterization to increase wind plant efficiency that reduces risk for developers.

Action: Deployed two research buoys that measure the weather and oceanographic data, which is made available to the public. This is crucial for developers to appropriately design, size and site projects to help determine how much power they can produce. When the Department of Energy is not using the buoys, they can be used by industry partners.

As wind farms move offshore, floating foundations are necessary to capture 60% of U.S. offshore wind resources located in deep water, where conventional foundations are not feasible.

Action: Supported the University of Maine’s development of a concrete floating foundation that uses less steel and can be produced at a lower cost to harness wind energy in deep waters. 

Action: To further lay the groundwork, we worked with the U.S. Department of the Interior to develop a joint strategy in 2016 to facilitate the development of the U.S. offshore wind industry and to achieve deployment levels consistent with the Wind Vision.


Taller wind turbines and long-needed electrical grid upgrades can open the door to expanding U.S. wind deployment. For example, increasing wind turbine tower heights from 80 meters to 140 meters would increase the technical potential for land-based wind by two-thirds, allowing more states, particularly in the Southeast, to benefit from wind power.

Action: Supported Keystone Tower Systems to develop an innovative spiral welding process for wind turbine towers. This in-field manufacturing method can cut tower costs (up to 180 meters tall) by 40%.

Action: Funded Iowa State University to develop the Hexcrete Tower, which uses prefabricated concrete components, enabling a taller tower without special transportation requirements. This pilot project showed that towers constructed in this manner can reduce the cost of wind-generated electricity by more than 20%.

Action: Released a January 2017 report which confirmed that adding even limited transmission can significantly reduce the costs of supporting levels of wind deployment consistent with the Wind Vision. The study found that building just four currently proposed transmission projects would halve the level of wind curtailment – the times in which wind farm operators are told not to produce energy due to limited grid capacity.


To increase America’s manufacturing competitiveness as identified in the roadmap, our wind and advanced manufacturing offices have teamed up with public and private organizations on new methods to produce wind turbine components.

Action: Applied additive manufacturing, also known as 3D printing, to the production of wind turbine blade molds. This process eliminates the need to manufacture a “plug” that is then used to form a mold, from which fiberglass blades can then be made. This reduces the time and cost required for blade manufacturing.

We also engage with collaborative research groups and make investments to fund research and development projects that address environmental and wildlife challenges from the deployment of wind energy.

Action: Funded Purdue University to develop a technology that will characterize golden eagle vision and hearing. The goal is to collect data for future systems that could make it easier for golden eagles to detect and avoid wind turbines.

Action: Funded Frontier Wind to develop and test an ultrasonic acoustic bat deterrent system comprised of an array of ultrasonic transmitters mounted along the length of turbine blades. High-frequency sounds from these transmitters will cover the entire turbine rotor, with the goal of deterring bats from wind turbines.


The government actions listed above move new technologies forward and help overcome barriers for adding wind energy. These investments, which benefit the industry and the economy as a whole, are leveraged and expanded upon by individual private companies. A new analysis by Navigant estimates that wind energy has an annual economic impact of about $20 billion on the U.S. economy. Continuing these investments in technology innovation and market barrier mitigation will help maintain and advance the nation’s existing wind manufacturing infrastructure and economic benefits, as well as ensure the United States remains globally competitive.

The Southwest Power Pool (SPP) just set a huge new wind penetration record: on March 16 a little over 60 percent of the system’s electricity came from wind power. That’s a big deal for a system that provides electricity to customers across 14 states.

SPP set a new wind-penetration record of 60.56 percent at 3:45 a.m. on March 16. Wind served 13,928.94 MW of the 22,998.71 MW total load. pic.twitter.com/7QEnE8LcFd

— Southwest Power Pool (@SPPorg) March 16, 2018

SPP serves many states right smack in the middle of the country where wind continues to grow– Iowa, Kansas, and Oklahoma, among others—so it’s no surprise that wind has routinely smashed penetration records over the past few months. In fact, SPP reports that wind has broken penetration records “six or seven” times in the past 90 days alone.

“Wind projects are costing only a fourth or less than what it cost to bring those online a decade ago because the technology has improved. The price of production has come down,” said Jim Roth, formerly a commissioner with the Oklahoma Corporation. “And, through the geographical diversity of the Southwest Power Pool’s footprint, the wind always is blowing somewhere,” boosting wind’s reliability.

Wind at these levels also saves consumers money. “That 60 percent getting dispatched Friday morning was the cheapest form of electricity on the grid,” Roth explained.

Importantly, wind at these high levels can be reliably integrated as technology continues to advance. That is upending the assumptions of just a few years ago.

“Looking back 10 years ago, we wouldn’t have thought this was possible,” said SPP’s Derek Wingfield. “We thought about 25 percent of wind penetration would be about all that anyone could handle reliably.”
