NRG’s Solar Thermal Power Project at Ivanpah Achieves Commercial Operation

NRG Solar’s Ivanpah Solar Electric Generating System is now operational and delivering solar electricity to California customers. At full capacity, the facility produces a gross total of 392 MW. Ivanpah is a joint effort between NRG, Google, and BrightSource Energy and Bechtel is the EPC contractor on the project. The project received a $1.6 billion loan guarantee from the US Department of Energy's Loan Programs Office. The facility achieved commercial operation on December 31, 2013.

Washington Gas Energy Systems Completes Solar Arrays at California Schools

Washington Gas Energy Systems completed two solar projects: one for Western University of Health Sciences and one for Corcoran Unified School District, both located in California. Both facilities will be owned and operated by Washington Gas Energy Systems under 20-year PPAs. The solar array at Western University is a 672-kW project with a roof-mounted system composed of 2,688 solar panels. Green Energy Partners developed the project; Conergy managed EPC activities. The 1,269-kW solar array at Corcoran Unified School District consists of 4,422 solar panels.

Putting a Price on Carbon

How EPA can establish a U.S. GHG Program for the Electricity Sector.

With the Environmental Protection Agency’s proposed greenhouse gas (GHG) emissions standards expected in June 2014, many states are considering their own approaches to provide flexibility in meeting compliance requirements. Experience in North America to date provides policy guidance.

Modernizing with Trackers

Time-tested cost recovery mechanisms provide stable funding for infrastructure replacement.

Automatic tracker surcharges provide timely cost recovery for multi-year utility system improvement programs.

Catching Fire

Climate policy heats up after the Great Recession.

GHG rules are coming soon. What happens next will depend on how states react.

Mathematical Structure of the Methodology

In this appendix to “Opening the Black Box,” (Fortnightly, January 2014), we briefly describe the basic components of the models for managing aging assets: how to represent the condition of such assets and the outcome of replacement, maintenance, and testing decisions.  

The model structure is one of optimal control with dynamic state variables and uncertainty. Let
