Geomagnetic Disturbances and the Grid

Harmonics Studies Needed to Assess Vulnerabilities

NERC recently issued reliability standards in response to the potential for geomagnetic disturbances to disrupt operations and possibly damage assets. The power industry appears to have placed undue emphasis on GMD’s threat to transformers. Our studies and those by others have underscored the value to transmission organizations in assessing their vulnerability to harmonics.

Reinventing the Grid

How to find a future that works.

The traditional central-station grid is evolving toward a more distributed architecture, accommodating a variety of resources spread out across the network. An open and thoughtful planning approach will allow an orderly transition to an integrated system – while fostering innovation among a wider range of industry players.

Don't Get Netflixed

The tide is turning. Are we planning for it – or hoping to stop it?

The central station system is the most cost-effective way to provide utility service, but that's beside the point. Customers don't care about 'utility service.'

Vendor Neutral

(December2012) KC Electric Association expects soon to finalize installing a Sensus FlexNet network and iCon A electric meters to serve about 4,000 residential and small commercial members across a 5,000-square-mile territory in rural Colorado. Itron and C3 Energy formed an alliance to integrate and jointly market an energy management solution to North American utilities. And others...

(December 2011) Lafayette Utilities System selects Elster’s EnergyAxis as its AMI system; ABB wins contract from Hydro-Quebec; Sapphire Power Holdings acquires gas-fired power generation from Morris Energy Group; Consumers Energy awards contract to Babcock & Wilcox; plus announcements and contracts involving BP Wind Energy, Abengoa Solar, Samsung C&T and others.

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.

Leaning on Line Pack

Green energy mandates might overburden gas pipelines.

Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.

Beyond Intermittency

Forecasting brings wind energy under control.

Advancements in forecasting have improved the reliability of day-ahead and hour-ahead estimates of wind generation. Wind never will behave like a base-load power plant. But as system operators integrate wind forecasts into their planning and market processes, they’re transforming intermittent wind energy into a variable but reliable resource.

A Fine Mess

CIP audits show utilities are just getting started with securing the grid.

Bad news from the front lines in the cyber-security war: Little meaningful progress has been made toward safeguarding the nation’s electric grid from malicious attacks. Initial cyber-security assessments and audits suggest few companies really are ready to implement the first wave of NERC critical infrastructure protection (CIP) standards, despite the fact the utility industry drafted the regulations.
