Transmission

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.

Ultracapacitors and batteries work together to solve power quality problems.

Given this dynamic state of evolution, it’s not surprising that next-generation technologies are undergoing their own difficult transitions. This transition is exemplified by four high-tech projects being executed by four electric utilities: Duke Energy, American Electric Power, Consolidated Edison and San Diego Gas & Electric. Their projects address different parts of the power-supply chain, and they’re taking different paths to secure financing and regulatory acceptance.

Various approaches to distributing emissions allowances spark a heated debate over costs and fairness, but the allocation methodology doesn’t determine whether a regulatory scheme will reduce emissions. Auctioning allowances and distributing them for free both offer advantages and challenges for a successful cap-and-trade system.

While many utilities have embarked upon efforts to define a path toward the next generation utility, these efforts often are siloed initiatives driven by the generation, transmission and distribution (T&D) or customer segments of the organization. Addressing the upcoming challenge will require a coordinated and integrated set of decisions so as not to sub-optimize the end-to-end value chain. Eight critical themes across the generation, T&D and customer elements of the value chain will shape the future of our industry.

A massive T&D system build-out is starting, but more needs to be done. Executives from Northeast Utilities, Pepco Holdings and ITC Holdings discuss improvements needed for reliability, capacity, security, smart-grid and demand-response measures, as well as accommodating wind and green-energy quotas.

As saving energy becomes a policy priority, utility commissioners struggle to reconcile traditional revenue models with smart metering and smart pricing. Unlocking conservation potential will depend on transforming passive ratepayers into smart consumers. Fortnightly hosts a roundtable discussion with commissioners from six states.

Money may be difficult to come by for Wall Street financiers in these dark days, but apparently not for electric transmission construction—at least so far. A rash of recent orders from FERC shows that generous financial incentives remain available to companies seeking to expand the nation’s grid capacity.

When a federal court ordered the DOE to develop more than 20 energy-efficiency rules, the first rule DOE created was a commercial rule for energy transformer distribution equipment. The new DOE rule, published at the end of last year, is the first increased efficiency standard created since the beginning of the Bush administration in 2001.

Contrary to conventional wisdom, electricity demand isn’t immune to price elasticity, and rate designs can encourage conservation. In particular, inclining block rates coupled with dynamic pricing can cut electric use by as much as 20 percent.
