As utilities plan their capital budgets for the next few years, investments in advanced distribution systems face an uncertain future. Customers question the value—and propriety—of some programs, while long-term strategic goals depend on seamless integration. What will be the path forward for smart grid technology?

Changes in regulatory requirements, market structures, and operational technologies have introduced complexities that traditional ratemaking approaches can’t address. Poorly designed rates lead to cross-subsidies, inequitable outcomes, and perverse incentives. An objective-based approach can better communicate costs to customers in a way that better serves operations and policy goals.

Are residential time-of-use prices only effective for middle class households, or do low-income customers benefit too—as authors Lisa Wood and Ahmad Faruqui asserted in their October 2010 article? Data from pilot programs show that low-income customers exhibit a reduced ability to benefit from dynamic pricing. Demand response programs should accommodate the realities of low-income customers’ consumption patterns.

Do low-income customers respond to dynamic rates? The answer is yes, and in fact such customers can benefit from dynamic pricing without shifting loads”contrary to conventional wisdom. A study co-authored by the Edison Foundation’s Institute for Electric Efficiency and the Brattle Group shows that restricting access to dynamic rates might actually be harmful to most low-income customers.

The business case for advanced metering infrastructure (AMI) can’t be justified alone on operational savings to the utility. But critical assumptions involving process improvements and system efficiencies depend on customer involvement. This sequel to a September 2009 article examines customer engagement strategies and techniques.

Making the business case for the smart grid is an important utility goal. It provides the justification for making or deferring required investments. Utilities might find it necessary to engage in a cycle of continuous strategic planning.

Siemens Energy has been awarded an 18-month, $300,000 R&D program by the Illinois Clean Coal Institute to study the effects of coal and coal-derived syngas combustion on the behavior of material and coating degradation in utility boiler and gas turbine environments. Focus areas of the research program will explore materials degradation modes in integrated gasification combined-cycle (IGCC) systems and utility boilers.
