T&D Grid

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.

The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the industry continue justifying the high cost of overbuilding?

Power delivery efficiency gains constitute a valuable utility asset that can offset or defer new generation and T&D investments. Enabling technologies, utility demonstration projects and supporting regulatory frameworks are needed to validate potential savings.

In light of all the excitement created by smart-grid regulatory initiatives and stimulus funding, three clever tech startups have come forward with proposals for novel grid projects. In California, Western Grid Development proposes to install energy storage devices ranging in size from 10 to 50 MW at various discrete and strategic locations in PG&E’s service territory where the California ISO has identified reliability problems. Second, a company called Primary Power proposes to deploy a total of four advanced, 500-MVAR static VAR compensators (SVC) at three separate locations within the PJM footprint. Third, in Clovis, N.M., Tres Amigas plans to allow power producers to move market-relevant quantities of electric power and energy between and among the nation’s three asynchronous transmission grids: ERCOT and the Eastern and Western Interconnections.

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.

Unlike the majority of performance-based regulation plans, alternative design paradigms require less data, by instead allowing firms to reveal performance potential. In an asymmetric environment, regulators don’t have needed information, but that can be overcome with better models and incentives.

The Northeast energy markets are working hard to establish new levels of regional coordination and cooperation. The region’s concerted effort is essential to resolving some of the industry’s toughest issues since the individual markets evolved. These issues include the elimination, reduction, or bridging of seams issues that prevent the economic transfer of capacity and energy between neighboring wholesale electricity markets, or control areas, as a result of incompatible market rules or designs.

In today’s modern business environment, standards for products and services have become common—and expected—practice. The time is right for creating a common language among the critical software tools needed to deliver a reliable, competitively priced supply of electricity through today’s integrated power grids and wholesale market structures.

During the 1980s and early 1990s, integrated resource planning (IRP) was a required practice for many utilities. Then competitive wholesale markets, merchant generation, and restructuring initiatives led many utilities to abandon IRP.

While wholesale competition generally has been successful, the regulatory process changes it brought were less so. And utilities now are getting back into long-term resource planning studies to provide decision support for their “back to basics” business strategies.

China is seeking to acquire resources and infrastructure from all over the world, from the oil fields of Venezuela to new shipyards for building liquefied natural gas tankers in Shanghai. But the country’s acquisition pattern puts it on a collision course with the United States and the rest of the world.
