What California can teach FERC about transmission planning.
The California ISO is going its own way with its proposal for transmission planning, virtually ignoring FERC’s proposed rules on transmission planning and cost allocation. California wants to bring method to the madness of developing transmission projects, and its approach has raised hackles in the industry. The dispute defines the battle over America’s most attractive market for rate-regulated investment.
Federal policy trumps state siting authority.
In some states, transmission projects have slowed to a halt as regulators attempt to substitute their own need determinations for those of RTOs. The federal framework encourages cooperation, but Congress and the courts have given FERC clear authority over interstate transmission systems.
FERC modifies its enforcement guidelines.
FERC’s revised policy provides greater predictability and transparency in the commission’s approach to determining civil and criminal penalties under its statutory authority. Despite a more systematic framework, however, FERC retains discretion to assess penalties based on the facts of individual cases.

Transmission cost allocation, the worth of the grid, and the limits of ratemaking.
A look at the issues that the Federal Energy Regulatory Commission must address concerning allocation of costs for certain high-voltage transmission lines 500kV or greater, planned for the PJM region, in the “paper hearing” on remand from the 7th Circuit federal court decision that rejected a socialized, region-wide sharing of costs among all utilities and customers across the RTO footprint.
Increasing renewable generation threatens reliability.
An increased reliance on renewable energy could threaten reliability of the nation’s electric transmission grids by reducing the rotational mass and rotational inertia of on-line turbine generators, thus, reducing the capability of generators to respond to drops in voltage frequency. In fact, data collected from 1994 to 2009 for the Eastern Interconnection already reveals a drop in the grid’s capability (as measured in megawatts) to stop a very rapid drop in frequency — such as a drop of a tenth of a cycle per second.
Shaping long-term smart-grid strategy.
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.
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.
The ZigBee Alliance and the Wi-Fi Alliance entered an agreement to collaborate on wireless home area networks (HAN) for smart-grid applications. The initial focus of the collaboration will be ZigBeeSmart Energy Profile 2.0, which is the next-generation energy management protocol for smart grid-enabled homes based on today’s successful ZigBeeSmart Energy Profile. The ZigBeeSmart Energy Profile 2.0 is expected to be extended to operate over Wi-Fi technology as a result of the collaboration.
Has the one-day-in-10-years criterion outlived its usefulness?
The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the industry continue justifying the high cost of overbuilding?
