Renewable Energy

A new wind turbine from Siemens can deliver reactive power.

NextEra Energy Partners' Bluewater Wind Energy Center in Huron County, Ontario has begun commercial operation. The project is comprised of 37 turbines and is capable of generating up to 60-MW of electricity. The Bluewater Wind Energy Center is owned by Bluewater Wind, LP, an indirect subsidiary of NextEra Energy Canada Partners Holdings.

Siemens Energy secured an order for a total capacity of 36 MW in Nordfriesland, Germany to supply twelve direct-drive wind turbines, eleven model SWT-3.0-113 and one model SWT-3.0-101 turbine, for the Süderlügum publicly-operated wind farm. Siemens has also been contracted for a 20-year service and maintenance agreement. Süderlügum has the ability to utilize renewable energy sources during calm weather by the "Reactive Power at No Wind" technology from Siemens. This option enables the wind turbines to stabilize the alternating current power grid when no wind is blowing, by producing reactive power and feeding this power into the grid. Installation for the Süderlügum wind farm is scheduled for late 2014.

The city of Palmdale completed an aggregate 976-kW DC solar generation project. Located at Palmdale's Civic Center, DryTown Water Park and Marie Kerr Park, the system is designed to generate more than 1,580 MW-hours of electricity per year and meet nearly 70 percent of the electricity needs for the three sites. Constellation financed the project's development and will own and operate the system. Palmdale will purchase the electricity generated by the system at a fixed-rate through a 20-year purchased power agreement (PPA) with Constellation. The solar power arrays are comprised of approximately 3,200 PV panels.

EDF Renewable Energy's 61- MW Spinning Spur II Wind Project in Texas has reached commercial operation. Spinning Spur II commenced construction of 87 GE 1.85-MW, 87-meter rotor wind turbines 40 miles west of Amarillo in June 2013. The power is sold pursuant to an 11-year purchase agreement. The project is one of the first to feed into the new CREZ (Competitive Renewable Energy Zone) transmission infrastructure. EDF Renewable Services will provide long-term operations and maintenance for the facility, balance of plant, project oversight, and 24/7 remote monitoring from its NERC compliant operations control center (OCC).

SheerWind’s INVELOX system funnels an augmented wind stream to ground-level turbines.

The Department of Energy (DOE) took the first step toward issuing a $150 million loan guarantee to support the construction of the Cape Wind offshore wind project with a conditional commitment to Cape Wind Associates. If constructed, the project would be the first commercial-scale offshore wind facility in the U.S., with a capacity of more than 360 MW of clean energy off the coast of Cape Cod, Massachusetts. The proposed Cape Wind project would use 3.6-MW offshore wind turbines that would provide a majority of the electricity needed for Cape Cod, Nantucket and Martha's Vineyard. Under the proposed financing structure for the Cape Wind project, the DOE would be part of a group of public and private lenders.

SunEdison acquired the 156-MW Comanche Solar project from renewable energy developer Community Energy.
