Distributed Energy Resources (DERs)

As utilities move towards distributed energy, the customer's role in the energy value chain increases dramatically. The utility's ability to influence mutually beneficial DER adoption and behavior will dictate whether or not DERs serve as an opportunity or threat

Integrating Renewable Energy into the Grid

Utilities and system operators are searching for cost-effective and reliable solutions. I think energy storage - batteries in particular - are at price points now where they represent a cost effective solution.

IEEE 802.16s Standard and Its Use for Distributed Energy Resources

The standard is now being leveraged to support applications at the grid edge including communication with distributed energy resources (DER) including solar, wind and local storage. DER applications are becoming increasingly important in supplying electricity.

California demand for wind power energizes transmission firms

Nichola Groom for Reuters:  A firm controlled by Philip Anschutz, the billionaire entertainment and pro sports magnate, will soon build the largest wind farm in the United States to serve utilities in California, where officials have set ambitious green power goals. The $5 billion project, however, will be constructed 700 miles away in Wyoming, a state better known for coal mines and oil fields. The vast distance between the two states provides a different Anschutz-owned firm with another big opportunity: a $3 billion project building transmission lines to deliver the power - one of a dozen similar power-line projects by other companies across the West. (Map: How wind power will get from Wyoming to California click here) In all, about 5,700 miles of transmission lines are in development with the goal of delivering renewable energy to California from other states, according to the Western Interstate Energy Board.   Cont'd...

Parker KleenVent provides closed-loop solution for wind turbine cooling systems

Many 1.5 MW wind turbines use traditional open-loop water/glycol cooling systems. Regular water evaporation in the reservoir elevates the mixture's viscosity, prohibiting cooling of the IGBT and associated critical controls, causing the wind turbine to overheat unless serviced, which in turn means turbine downtime and high maintenance costs. Parker's KleenVent Coolant Evaporation Inhibitor (KV-CEI) is a simple add-on to the legacy cooling system, that eliminates water evaporation in the coolant solution and stops the ingress of airborne contaminants, by enclosing the cooling loop. The KVCEI also removes the need for continuous coolant monitoring during the warm season. Traditional maintenance calls to replenish or rebalance the fluids, take the wind turbine and transformer offline, resulting in significant downtime and revenue loss. Parker's cooling system solution optimizes wind turbine uptime and revenue, reduces maintenance costs and increases overall efficiencies.
