The CAPX2020 Model: Part II

One of the most ambitious transmission projects in America today is CAPX2020. In this second of two exclusive interviews, Fortnightly's Spark talks with Teresa Mogensen, Xcel Energy’s vice president of transmission, about how the investor-owned utility collaborated with public-power utilities to develop a complex set of lines and a solid investment for shareholders.

FORTNIGHTLY  What’s Xcel Energy’s role in the CAPX2020 project, and how does it fit into the company’s overall transmission plan and resource plan?

MOGENSEN CAPX2020 is very important for Xcel and the region.

The CAPX2020 Model - Part I

One of the most ambitious transmission projects in America today is CAPX2020, a series of lines in Minnesota and surrounding states. In this first of two exclusive interviews, Fortnightly's Spark talks with Will Kaul, Great River Energy’s v.p. of transmission, about how the project managed to succeed where others have failed.

Recently electricity started flowing through a new power line between Monticello and St. Cloud, Minn. This 28-mile, 345-kV segment represents a major milestone for one reason: it’s the first wire to go live in the 700-mile CAPX2020 transmission venture.

Cyber War!

The United States is the superpower of cyber warfare, but we aren’t alone in possessing these capabilities. Sophisticated attacks raise new concerns about utility vulnerabilities -- SCADA systems in particular.

The year 2011 may have forever changed the way we think about the security of networks and systems. Following a year many are calling the “year of the hack,” security professionals have fundamentally changed their outlook when it comes to the threat of a network breach. Whereas previously, many considered a breach unlikely and more of an “if” scenario, many have shifted to a mindset of “when.”

Climate Exposure

A state supreme court ruled last fall that damage resulting from climate change allegedly caused by power plant emissions was “reasonably foreseeable,” and therefore litigation expenses were not covered under a general liability insurance policy. The ruling creates an unworkable standard and raises questions about insurance coverage for climate-change liabilities.

While the policyholder was left adrift by Steadfast, the climate change insurance ship certainly hasn’t sailed.

On Sept. 16, 2011, the Supreme Court of Virginia became the highest state court in the country to rule on the issue of insurance coverage for climate-change claims under a general liability policy. In AES Corp. v. Steadfast Ins.

Frequency Regulation

In a recent order, the Federal Energy Regulatory Commission (FERC) said that by paying the wrong price for the ancillary service known as frequency “regulation,” system operators have encouraged too many gas-fired turbines and other conventional fossil power plants to supply regulation service.

Putting market economics ahead of reliability, the Federal Energy Regulatory Commission (FERC) has told regional transmission organizations (RTOs) and other grid system operators (ISOs) to rethink the prices they pay for the ancillary service known as frequency “regulation.”

In short, FERC wants all power plants to do what they do best — recognizing that some may be well adapted to providing regulation service, but others perhaps not.
