NREL Studies of Voluntary Markets Draw Positive Feedback from Utilities


NREL analysts Jenny Heeter and Lori Bird presented at the 2012 Renewable Energy Markets Conference, a premier national forum for promoting renewable energy.

Heeter presented Innovations in Voluntary Renewable Energy Procurement: Methods for Expanding Access and Lowering Cost for Communities, Governments, and Businesses, which explores five innovative options for voluntarily procuring renewable energy generation or systems. Bird discussed Market Brief: Status of the Voluntary Renewable Energy Certificate Market (2011 Data), which documents the status and trends of voluntary markets—those in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis.

Heeter, who led the development of the two papers, said she received "a lot of positive feedback from utilities on our work tracking trends in the voluntary market."


Chart showing estimated annual voluntary sales by market sector, 2006-2011. There are four data sources for the estimates: NREL Estimated Total Voluntary Market, Green-e Energy Retail Sales, EPA-GPP Sales, and Tracking System Estimate. 2006 shows a range from approximately 4 million (Green-e) to 12.5 million (NREL) megawatts annually. 2011 shows a range from approximately 22 million (EPA-GPP) to 37.5 million (Tracking System) megawatts annually.

OpenEI Spotlighted in White House Datapalooza Event

The Hydrogen Gateway on OpenEI launched in preparation for Energy Datapalooza, an event that highlights the use of open energy data sourced from the government and used by entrepreneurs to build new businesses.

At the event, Dr. David Danielson, assistant secretary for EERE, mentioned OpenEI (Open Energy Information)—a knowledge-sharing online community dedicated to connecting people with the latest energy information and data. Debbie Brodt-Giles said he "mentioned OpenEI as being DOE's platform for sharing open data." In addition, several teams stated that they use OpenEI and NREL data in their applications that were highlighted and demonstrated at the event.

"It was a very inspirational event, and it was great to see so much support for open energy data!" exclaimed Brodt-Giles.

The Hydrogen Gateway provides relevant links to reports, such as National Fuel Cell Electric Vehicle Learning Demonstration Final Report, and to HyDRA (Hydrogen Demand and Resource Analysis), which is a web-based GIS tool that allows users to view, download, and analyze hydrogen demand, resource, and infrastructure data spatially and dynamically. One the most interesting features of the gateway is the Hydrogen Composite Data Product Directory that can be searched by topic. It is a visual representation of data, and the plan is to provide more visualizations and access to raw open data in the future, which is directly in alignment with the government's Energy Data Initiative.


Reminder: NREL to Present Webinar on Geothermal FIT Design


NREL will hold a webinar to discuss research, analysis, and results from a new report: Geothermal FIT Design: International Experience and U.S. Considerations. The presentation will explore specifics on how feed-in tariff (FIT) policies can be designed to address certain risks of geothermal power plant development.

Date: Tuesday, October 9, 2012
Time: 1–2 p.m. ET (10–11 a.m. PT)

NREL Analysis and Analysts in the News


RenewableEnergyWorld.com reposted NREL blogs "Municipal Bond: PPA Model Continues to Provide Low-Cost Solar Energy" by Bethany Speer and "Geothermal Transmission 101: Technologies Are Not Treated Equally" by Paul Schwabe.

At the International Life Cycle Assessment (InLCA) conference, Garvin Heath gave four presentations and Ethan Warner gave one on articles resulting from the LCA Harmonization Project. Heath said, "Much positive feedback was received on the presentations, especially the timely new results on natural gas systems." NREL is now a Silver-level institutional member of the American Center for Life Cycle Assessment, which is who puts on the annual InLCA conference.

Laboratory Design's article "NREL Database Reveals Technology Costs" highlighted NREL's Transparent Cost Database.

Paul Denholm and Mark Mehos wrote "Boosting CSP Production with Thermal Energy Storage" for Power Magazine, which is based on NREL technical report Enabling Greater Penetration of Solar Power via the Use of CSP with Thermal Energy Storage.

Garvin Heath and Debbie Sandor wrote "How NREL is Improving GHG Calculations for Power Plants" for GreenBiz.com, which summarizes the LCA Harmonization Project that was highlighted in a special supplemental issue of the Journal of Industrial Ecology. On the day this blog posted, there were 37 tweets about it.

Andy Reger and Lori Bird recently hosted a webinar, "Best Practices in the Design of Utility Solar Programs," that brought together representatives from industry, utilities, and regulatory authorities to share insights into the lessons learned from designing and implementing solar energy incentive programs.

At the annual member advisory meetings of the Electric Power Research Institute (EPRI), Garvin Heath presented research on the land use of wind, solar, and geothermal electricity generation technologies conducted at NREL and sponsored by EPRI.

Garvin Heath presented "Life Cycle GHG Emissions and Water Consumption from the Manufacture of an ATS Heliostat" at the international SolarPACES conference on CSP.
