Renewable portfolio standard

Embracing Wind

Integrating renewables in New York.

New York has developed new market mechanisms intended to effectively incorporate large amounts of renewable energy in the future — up to six times the current levels of intermittent energy without impacting system reliability. New York ISO executive Rana Mukerji explains how the market will drive new investment in renewable energy in the state.

Conquering Time

Understanding the value of pumped storage.

Pumped-storage technology allows utilities to defer the time value of energy, but project developers have struggled to make their economics work. Increased demand for ancillary services and standby capacity might make pumped storage more viable.

RPS Race

As green mandates tighten, utilities scramble to comply.

Mandatory renewable portfolio standards are becoming the norm. But after low-hanging green fruits are harvested, renewable power might get scarce. Many utilities will struggle to meet RPS requirements until lawmakers create stable federal policies and a national market for green credits.

Coal: Inconvenient Truths

The current coal bust might lead to a future boom.

Coal is taking a beating. As mining costs rise, coal reserves deplete, emission regulations strengthen, and inter-fuel competitive dynamics change, the allocation of coal in the electric generation industry is certain to see substantial changes. The uncertainties over CO2 regulations and emissions standards are having a chilling impact on both proposed and current coal investment.

Before You Build It: Think Green

The complex financial analysis that has driven renewable energy investment has become the standard for assessing all potential electric generation investments.

Tax incentives, renewable portfolio standards, and the creation of renewable-energy credits and carbon constraints are no longer separate considerations when assessing renewable-energy projects. The convergence of these economic considerations will affect the value proposition for every potential generation investment in the United States.

Northwest Passage: BPA's Changing Role

The treacherous journey toward a more efficient and transparent Northwest power market may be nearing its conclusion.

The treacherous journey toward a more efficient and transparent Northwest power market may be nearing its conclusion.

Steve Wright stands at the helm of an agency with a seemingly impossible task. As CEO and administrator of the Bonneville Power Administration (BPA), Wright must serve a broad spectrum of interests, from aluminum smelters to sockeye salmon. And no matter what he or anyone does, it's impossible to make them all happy at the same time.

Green Electricity: It's in the Eye of the Beholder

SOME PEOPLE WANT TO KNOW WHAT "GREEN POWER" means (em and, by extension, "environmentally friendly." Does that mean low emissions, including nuclear energy? Is renewable energy automatically green? Should the simple fact of compliance with all standards imposed by the Environmental Protection Agency afford the right to advertise power generation as green?

Consumers, agencies and state and federal officials want truth in advertising. Proponents of alternative generation claim consumers are willing to pay more for cleaner, greener energy.
