Tres Amigas Tie Up

Synchronizing networks to bring green power to market.

In order to fully integrate wind and other dispersed sources of energy into the system, America’s patchwork transmission networks need to be more closely interconnected and synchronized. An advocate for the Tres Amigas merchant transmission project explains how the proposed facility will integrate the grid.

Green Energy Outlook

Realizing the benefits of a modernized system requires an integrated strategy.

The U.S. power market consistently has displayed cyclical characteristics of boom and bust over the last two decades. Today’s market environment has been directly and significantly impacted by the recent economic recession. Decreases in load growth, declining commodity prices, and lack of accessible financing have caused challenges for the industry.

Renewable Reality Check

How solar PV could redraw the map for green energy and grid investment.

When Pacific Gas & Electric broke the news six weeks ago that it had signed a deal with Solaren Corp. to buy 200 MW of solar energy from satellites launched into geosynchronous orbit, the idea seemed almost laughable. Solaren’s plan is to catch unobstructed sunlight falling on arrays of photovoltaic solar panels deployed in the crystalline void of outer space, and then to convert the generated electricity into radio-frequency energy for transmission to Solaren’s ground-based receiving station outside Fresno. Welcome to the new renewable reality.

Federalizing the Grid

Renewable mandates will shift power to FERC but pose problems for RTOs.

A recent survey conducted by the U.S Office of Personnel Management and reported by the Washington Post on March 13 ranked the Federal Energy Regulatory Commission as eighth best of some 37 federal agencies in terms “talent,” and third in “leadership and knowledge.”

Dynamic Pricing Solutions

How to account for lack of strong price signals. A hard year puts deregulation to the test.

The greatest benefits of time-of-use pricing come from avoided costs of peaking power and T&D capacity—but only if hourly retail prices accurately model the true costs of delivered energy, including scarcity rents. Restoring the missing price signals will encourage economic investments in AMI, conservation and system capacity.

The Queue Quandary

Why developers today are often kept waiting to get projects ok’d to connect to the grid.

Late last year FERC learned that the Midwest regional grid likely would require at least 40 years — until 2050 — simply to clear its backlog of proposed gen projects awaiting a completed interconnection agreement to certify their compatibility with the interstate power grid. But grid engineers would meet that date only by shortening the process and studying multiple projects simultaneously in clusters. To apply the process literally, studying one project at a time, as envisioned by current rules, the Midwest reportedly would need 300-plus years to clear its project queue.
