Chicken-Egg Solution

Solar and wind developers learn to shift project risk to the grid.

As Google says, “the wind cries for transmission.” But the opposite is true as well: without new wind and solar energy projects, we would not need to build so many new transmission lines. Each side needs the other, yet neither dares declare too soon, and risk weakening its bargaining position. That is, until one utility in California found a way to break the impasse, with each side scratching the other’s back — thus putting to rest the age-old question, “Which came first, the . . . ?”

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.

First Refusals, Least Regrets

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.

Taking Green Private

How merchant funding is remaking the rules for renewables.

Six weeks ago, FERC opened a notice of inquiry to invite industry comments on whether wind, solar, and other intermittent energy sources face unfair obstacles in wholesale power markets. Now assigned their own acronym—VERs, for “variable energy resources”—renewables make up a growing percentage of the nation’s energy supply portfolio. But as FERC notes, they present “unique challenges,” especially in terms of constraints on location and limits on the degree to which system operators can control or dispatch individual VER units. Thus, FERC suggests that certain common rules and practices, such as those for unit commitment, dispatch, and scheduling, might make it overly difficult to integrate VERs into the grid.

Outsmarting the Grid

A trio of eager tech startups confronts an industry intent on preserving the status quo.

In light of all the excitement created by smart-grid regulatory initiatives and stimulus funding, three clever tech startups have come forward with proposals for novel grid projects. In California, Western Grid Development proposes to install energy storage devices ranging in size from 10 to 50 MW at various discrete and strategic locations in PG&E’s service territory where the California ISO has identified reliability problems. Second, a company called Primary Power proposes to deploy a total of four advanced, 500-MVAR static VAR compensators (SVC) at three separate locations within the PJM footprint. Third, in Clovis, N.M., Tres Amigas plans to allow power producers to move market-relevant quantities of electric power and energy between and among the nation’s three asynchronous transmission grids: ERCOT and the Eastern and Western Interconnections.

Wellinghoff's War

FERC fights for the green-grid superhighway—even if Congress won’t.

The Senate’s deadlock over carbon cap-and-trade legislation has not deterred FERC Chairman Jon Wellinghoff from an agenda bent on promoting renewable energy and fighting climate change. Last fall, even as Congress dithered, FERC launched a landmark initiative that likely will lead to sweeping new rules for expanding the nation’s electric transmission grid, grounded on Wellinghoff’s belief in wind, solar, and green power resources.

Green Contracting

Structuring renewable agreements to survive change.

The potential for a federal renewable energy standard (RES) and carbon regulation, considered with the effect of state-imposed renewable energy standards, is fueling a strong, but challenging, market for renewable energy. Utilities are competing to sign up the best new projects, the types of renewable technologies available are increasing, and there are various government stimulus programs for energy; yet, the financial markets still are hesitant. Against this backdrop, how should contracts for power from new renewable resources be shaped so that those deals will look as good five, 10 and 15 years after execution as on the day the ink dries?

RTOs and the Public Interest

Defining the mission when the consumer plays second-fiddle to the needs of the market.

Six months back, when ISO New England was mulling over various reforms that FERC had mandated last fall in Order 719 for the nation’s six regional transmission organizations and independent system operators (RTOs and ISOs are interchangeable terms in this column), the ISO refused point blank to include in its mission statement a proposal by stakeholders that it should operate the bulk power system at the “lowest reasonable cost.”

The Smart-Enough Grid

How much efficiency do ratepayers need—and utilities want?

When the applause dies down, the smart grid may turn out to be its own worst enemy. The California Independent System Operator (CAISO) explained this irony in comments it filed in May, after the FERC asked the industry for policy ideas on the smart grid.
