New upgrade to state's power grid proposed

ST. PAUL, Minn. - An upgrade of the state's power grid would include a $600 million high-voltage transmission line from the South Dakota border to the Minneapolis-St. Paul area - and that's just part of the plan proposed by a coalition of utility companies. The plan also calls for a second high-voltage line from Fargo, N.D., to the St. Cloud area, a third line from the Minneapolis-area to Rochester and then to La Crosse, Wis., and a smaller fourth line in the Bemidji area.

Kicking Oil Addiction: Minnesota Becomes First State to Endorse an Electric-Alcohol Strategy

Minnesota Governor Tim Pawlenty has signed into law H.F. 3718, the nation’s first law promoting plug-in hybrid, flexible-fueled vehicles. The legislation – inspired by the Institute for Local Self-Reliance's report A Better Way that proposed an electricity-alcohol transportation energy strategy, and several articles by ILSR staff published in the Star Tribune in late 2005 – sailed through both houses by a unanimous vote.

AAA, or assiduous acronym avoidance

Voegeli eventually drifted back to an acronym-littered update. “We need a CUP for the PUC,” he said, meaning that the turbine needs a conditional use permit before the Public Utilities Commission, which oversees Xcel Energy, will vote on approving any agreement.

Which way will wind blow on turbine proposal?

Winona County’s economic development authority revealed several more details and funding proposals for a proposed 2-megawatt turbine during a work session Tuesday, as preparations move toward a vote on final approval later this year. The county board will be asked next Tuesday to approve $48,000 to complete studies for the turbine.

Grid Impacts of Wind Power Variability: Recent Assessments from a Variety of Utilities in the United States

Ewec06gridpaper_thumb In this report we discuss some recent studies that have occurred in the United States since our previous work [2, 3]. The key objectives of these studies were to quantify the physical impacts and costs of wind generation on grid operations and the associated costs. Examples of these costs are (a) committing unneeded generation, (b) allocating more load-following capability to account for wind variability, and (c) allocating more regulation capacity. These are referred to as “ancillary service” costs, and are based on the physical system and operating characteristics and procedures. This topic is covered in more detail by Zavadil et al. [4].

County EDA receives towers to assess wind

Within the next week, the Winona County Economic Development Authority (EDA) could be the proud recipient of two meteorological towers on loan from the Minnesota Department of Commerce, according to EDA member Anne Morse. A meteorological tower, or “met tower,” is typically a structure between forty and fifty meters tall that provides a setting for an anemometer, a device that gauges wind.

Wind energy holds potential but faces barriers

"To push harder for renewables, we need to have data in order to do it responsibly," said Bull. "In the meantime, while we're doing this, we're focused on wind energy and natural gas costs and pushing utilities beyond where their comfort level is. We'll continue to push for more renewables where we see the benefits to consumers."

Bird debate follows turbine plans

During a tour last month of Carleton College's 1.65 megawatt turbine in Northfield, Minn., project director Rob Lampa told a group of about 30 Winona County residents that the college had found no evidence of bird or bat kills in the first year of operating the 230-foot turbine ... As the group was leaving, Winona resident Marijo Reinhard pulled County Commissioner Dwayne Voegeli aside. "Look," she said, pointing at the ground, where she had spotted a small, brown bat dead on the gravel; A few feet away, she spotted another, also dead.
