Case studies on integrating renewable resources.
Seth Parker, Jack Elder, and Boris Shapiro
Where wind integration has been most successful, state authorities developed and adopted basic transmission planning and cost allocation principles before FERC issued Order 1000. Experiences in Texas, California, and Hawaii demonstrate what it takes to overcome permitting and cost allocation barriers—namely, a coherent policy framework and close coordination among stakeholders.
(July 2011) Williams Partners L.P. expands Transco transmission lines; Google to provide fiber optic Internet service for Kansas City, Mo.; Constellation Energy picks Lynxspring Inc.; plus contracts and developments involving Servidyne, EnerNOC, Siemens Energy and others.
Preparing the grid for large-scale renewables.
With large solar arrays and wind farms being proposed to connect to transmission and sub-transmission systems, are utility companies sufficiently prepared to handle the challenge of integrating these large intermittent resources? The industry now must decide whether transmission reliability factors — most notably dynamic voltage support and system frequency management — need to be resolved by renewable generators, or whether they should become a cost of doing business for transmission providers and reliability coordinators.
Investment opportunities in an evolving environment.
Christopher Dann, Sartaz Ahmed and Owen Ward
Some of the key policy mechanisms and market factors that triggered the boom in renewable energy development have weakened in the face of one of the most severe economic downturns in modern history. In some ways, though, the renewables sector is richer and more dynamic today than when the boom began. A shakeout might be coming among renewable power players, and those that survive will strengthen their capabilities, hone their strategies, and take advantage of industry consolidation to build scale.
(March 2011) TVA and EPRI demonstrate solar-assisted EV charging station; Ford unveils the all-electric Focus; Central Maine Power awards substation contracts; ERCOT deploys ABB software in nodal market; FirstSolar starts up PV plant for Southern Company and Ted Turner; plus contracts and announcements involving Open Systems International, Verizon, Suntech Power, Alcatel-Lucent, Siemens, Cisco, Elster, Sensus, Silver Spring Networks and others.
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.
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.
Lawmakers are rushing a costly decision.
Utilities are struggling to predict the costs of greenhouse gas regulation. In the quest for a greener planet, how much should consumers be asked to pay for environmental benefits that might be difficult to measure?
New approaches account for the economic benefits of renewables.
Many green power customers benefit from long-term fixed prices. The most effective programs recognize the value of this price hedge—and fairly exempt customers from fuel cost adders in utility rates.
Sweating the details for 2009.
The Electric Reliability Council of Texas (ERCOT) introduced wholesale market competition in 1996, following the organizational change of ERCOT from a pure reliability council to an independent system operator (ISO) the same year. This makes ERCOT one of the earliest adopters of competitive electric markets. Stakeholders and regulators in ERCOT are trying to work out the details of implementing this market.
