Enel commissions two wind parks in the United States (173 MW)


News date: 

Italian energy group Enel, through its subsidiary Enel Green Power North America, has commissioned two wind projects in Oklahoma (United States).

The 108 MW Drift Sand project worth US$180m, located in Grady County, is expected to generate around 480 GWh/year. The 65 MW Chisholm View II wind project, worth US$90m, is an expansion of the existing 235 MW Chisholm View wind and increases the plant’s capacity to 300 MW. Located in Grant and Garfield Counties, the project is expected to generate around 240 GWh/year, enough to supply 19,000 U.S. households while avoiding 126 ktCO2/year. The parks’ generation will be sold under bundled, long-term power purchase agreements.

With the commissioning of these two parks, EGPNA now manages the second largest wind capacity in Oklahoma with 8 wind parks totalling 952 MW. The company operates more than 2.6 GW of wind, solar, geothermal and hydropower plants in 23 US states and two Canadian provinces.

PV growth to slow sharply after strong 2016: IHS Markit

PV growth to slow sharply after strong 2016: IHS Markit


Global PV installation additions will slow to a crawl next year after registering a 34% year-on-year expansion in 2016 – and completing an uninterrupted 10 years of growth, said analyst IHS Markit.

The research group expects the world to end the year with an extra 77GW in place, with strong demand from China driving another bumper year following the 32% year-on-year growth seen in 2015 – the first time this decade that expansion has beaten 30% for two years in a row.

The 2016 growth was stronger than expected thanks to a dash in China to advance projects ahead of feed-in-tariff (FIT) changes announced in September, said IHS Markit.

But the analyst’s forecast for 2017 is for a far more modest new capacity growth of 3%, with 79GW expected to be added, followed by “two years of single-digit growth before a stronger market recovery in 2019”.

That is due to a slowdown in installations in the world’s two most important PV markets – China and the US.

Josefin Berg, senior analyst, IHS Technology, said: “Until China officially publishes the changes to the FIT rates, and the timeframe for the reductions, the forecast for total installed capacity in 2017 and the quarterly distribution remain highly uncertain.”

IHS Markit pointed out that China has lowered its 2020 minimum solar target to 110GW from 150GW. “This reduced ambition reflects a projected decline in additions of Chinese additions in 2018, followed by relatively flat demand in subsequent years, enough for China to exceed its target and reach 169 GW of cumulative installed capacity in 2020.”

India will become the world’s number-three solar market with a predicted 10GW of additions in 2017, overtaking Japan, added IHS Markit.

Aquanis granted funding to develop & test its blade-mounted flow actuator

Aquanis granted funding to develop & test its blade-mounted flow actuator


Aquanis announced that it has received a National Science Foundation (NSF) Phase I Small Business Innovation Research (SBIR) grant of $224,969 for the development and testing of a device that promises to improve the efficiency and extend the service life of utility-scale wind turbines.

The company also was awarded an Innovation Voucher grant from the Rhode Island Commerce Corporation, which will provide $50,000 in funding to support the company’s research partners in Brown University’s School of Engineering.

Aquanis plans to use actuators on wind turbines to affect the flow of wind around the turbine blades, reduce turbulent air, and maximize aerodynamic performance. Learn more about the device here.

According to Aquanis, to build larger, more efficient, and durable wind turbines, designers must find a way to mitigate fatigue loads in the turbine blades caused by unsteady aerodynamic forces. But all of the remedies tried to date have moving parts, and are costly and complex to implement.

The company is, therefore, developing a new device that can address the problem with no moving parts and minimal blade modifications.

The Aquanis system features a blade-mounted plasma flow actuator, which is a software-controlled solid-state electrical device that is simple and inexpensive. The system is based on patented technology developed at the University of Notre Dame, and Aquanis has acquired an exclusive license to the patent portfolio for the wind energy field of use.

“We are excited about this Phase I SBIR grant, which will give us the opportunity to make the technology viable at ever larger scales,” said Aquanis CEO Neal Fine. “The simplicity of our plasma actuator technology provides the basis for an inexpensive, nomoving-parts control system that will allow wind turbines to react instantly to changes in the wind.”

The market for this device includes all new wind-turbine construction – currently 25,000 utility-scale turbines per year with total capacity of 63 GW. This market is expected to continue growing by 12% per year through 2025.

The customers that Aquanis is initially targeting are the top 10 wind-turbine manufacturers, including Vestas, Siemens, GE, Goldwind, Enercon and Suzlon — which, combined, own about 70% of the global market. The six-month NSF grant will fund the development of a new actuator design that is expected to at least double the efficiency of the device.

To explore a wide range of system designs, the company needs access to state-of-the-art computational tools. The RI Innovation Voucher provides just that, with access to Brown University researchers who have developed advanced computational fluid dynamics tools that will assist in the Aquanis’ product design.

“We are thrilled to be working with our colleagues at Brown University on this Innovation Voucher grant,” said Fine. “Brown’s computational resources will help to cut years off of our product development cycle.”
