Integration

Solar Screen Test

Making room on the local grid for small-scale PV.

For the first time, perhaps, the electric utility industry may need to keep track not only of peak load, but also of minimum load, as the Federal Energy Regulatory Commission reviews a proposal by the Solar Energy Industries Association to employ a new definition of minimum load under a new, relaxed threshold test that would govern eligibility for fast-tracking of applications by generation developers to interconnect new, small-scale solar energy projects to the local utility distribution grid.

Big Data

The buzzword of the day is ‘analytics.’ But what does it mean?

As utilities seek to extract value from their technology assets, smart grid and metering data is becoming a gold mine for insights about how to improve service and save money. Fortnightly’s Alyssa Danigelis speaks with experts in the growing field of data analytics, to learn how big data might reshape the utility landscape.

Transmission's True Value

Adding up the benefits of infrastructure investments.

Allocating the costs of new transmission investments requires accurately assessing the value of those new lines, and identifying the primary beneficiaries. But formulaic approaches rely too much on the most easily quantified cost savings, and reject benefits that are dispersed across service areas—or that might change over the course of time. Brattle Group analysts J.P. Pfeifenberger and D. Hou explain that comprehensive valuation produces a more accurate picture.

Not-So-Green Superhighway

Unforeseen consequences of dedicated renewable energy transmission.

Achieving aggressive renewable energy goals will require building thousands of miles of new transmission lines, and these so-called “green-power superhighways” could bring major new sources of low-cost electricity into the market. But will those sources be renewables? Analysts Roger Bezdek and Robert Wendling argue that with new access to distant wholesale markets, coal-fired generation would become more competitive than ever.

Green Gridworks

Case studies on integrating renewable resources.

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.

Trusting Capacity Markets

Does the lack of long-term pricing undermine the financing of new power plants?

The PJM Interconnect’s Reliability Pricing Model generally has succeeded in attracting and retaining low-cost generation and demand resources to maintain resource adequacy. But sluggish demand and low prices have weakened the market for long-term capacity contracts. Suppliers aren’t willing to lock in current low prices, and buyers don’t want to pay more for future certainty. Is the market dysfunctional, as some state lawmakers suggest, or does the lack of long-term contracts indicate a rational balance of supply and demand?

Killer App

Distribution management at the smart grid frontier.

The hype over smart grid has become focused on the idea of “advanced distribution management systems” (ADMS). But so far, few utilities have implemented ADMS beyond pilots and incremental tests. Fortnightly analyzes the technology trends and profiles examples of true ADMS in action.

Bonneville's Balancing Act

In the Pacific Northwest, you either spill water or spill wind.

The wind power industry has been up in arms ever since the Bonneville Power Administration earlier this year announced its Interim Environmental Redispatch and Negative Pricing Policy. That policy, applicable during periods of high spring runoff and heavy water flow volumes on the Federal Columbia River Power System, calls for BPA to redispatch and curtail access to transmission for wind power generating turbines, and to replace that resource with hydroelectric power generated via BOA hydroelectric dams, in order to avoid having to divert water through dam spillways, which could threaten fish and wildlife by creating excess levels of Total Dissolved Gas (TDG), which can cause Gas Bubble Trauma. Yet the legal issue remains unclear: Does this practice imply discrimination in the provision of transmission service, or is it simply a matter of system balancing and generation dispatch? In fact, the FERC may lack jurisdiction over the dispute, as it pertains to the fulfillment of BPA’s statutory mandates.

Grid 2050

Shaping system transformation.

New technologies—and new expectations—require taking a fresh look at the institutions and practices that have provided reliable electricity for the past century. Collective action is needed to define the key attributes of a future grid and then to take the more difficult next step—adapting our processes and institutions to align with that future vision. A thoughtful approach will allow America to capture the potential value that’s offered by sweeping changes in technologies and policies.

Cyber Attack!

Protecting critical assets in a hazardous world.

In the wake of recent global-scale cyber intrusions, security concerns have expanded from being compliance and operational issues to fundamental risk management considerations. An integrated, enterprise-wide approach holds the greatest promise for securing critical utility infrastructure against increasing dangers in cyberspace.
