Reconsidering Resource Adequacy, Part 1

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?

NERC Today and Tomorrow

Living in the new world of mandatory reliability standards.

Mandatory reliability standards put in place by NERC three years ago give reason for optimism concerning their success. But the organization struggles with standards development, compliance, enforcement and transparency.

Local Renewables

An emerging model for green power.

Certain New Jersey counties have undertaken a regional, public-private partnership approach to developing renewable energy projects for local government buildings. Local governments generally include municipalities, school districts, counties, and municipal or county or other regional sewerage or water utilities, depending on applicable state law.

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.

Real Green Costs

Valuing risk reduction for renewables and DSM.

Resource planners are faced with complex choices for developing cost-effective and robust energy supply portfolios. These choices are complicated by uncertainties inherent in future fuel and emissions costs. In the summer of 2008, retail energy providers with supply primarily from wind generation had a substantial cost advantage over gas-fired generation. In the summer of 2009, though, gas prices plummeted in the wake of the recession. Reversing the previous trend, this shift causes wind generation to appear more costly relative to gas-fired generation.

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.

Buying Into Solar

Rewards, challenges and options for rate-based investments.

Utilities traditionally have met renewable portfolio standards with power purchases from IPPs. But new approaches are allowing utilities to build their rate bases with investments in solar generation.

Negawatt Pricing

Economists take sides in the battle for DR’s soul.

Back when the U.S. economy and power consumption still were bubbling, PJM reported in August 2006 that customer curtailments during a week-long August heat wave had generated more than $650 million in market-wide energy savings—all at a mere $5 million cost, as measured in direct payments made to the demand response (DR) providers, set according to wholesale power prices prevailing at the time. Where else but the lottery can you get an instant payoff of 130-1?

The New Green Finance

The best way to tap into renewable project funding.

Renewable generation resources have become the rallying cry for policymakers and developers alike as the movement grows to generate electricity in a more climate-friendly manner. Pending federal legislation creating a carbon cap-and-trade market and a national renewable portfolio standard (RPS), together with existing state requirements, is spurring utilities that lack renewable generation to acquire some—no matter the federal legislative outcome—and causing utilities with sizeable renewable generation to expand their existing portfolios.

Assessing Construction Compliance

Gas utilities can make better use of their inspection budgets.

An entirely new and better approach to measuring risk and compliance allows companies actually to measure this kind of risk—that is, to measure the degrees of compliance regarding actual field practices versus written standards and procedures.
