Renewables...Storage...What's next?


Published on

Terry Mohn, Chief Innovation Officer, Balance Energy Vice Chairman, GridWise Alliance

Implementing large renewable energy resources: Is storage the solution to renewable generation?

• Deploying carbon reducing technologies such as wind,
solar, geothermal and plug-in vehicles
• Meeting the challenges of storage and transportation of Renewable energies such as wind and solar
• Developing a smarter grid in which users can produce their own power and provide its own localized storage

Renewables...Storage...What's next?

  1. 1. Charged2020: Energy Storage Forum June 30 – July 1, 2010 University of San Diego, San Diego, CA Renewables… Storage… What’s next? Terry Mohn Chief Innovation Officer, Balance Energy Vice Chairman, GridWise Alliance © 2010 Balance Energy All Rights Reserved

  3. 3. Large Wind and Solar Farms NREL 2009 Report • Since 2000, renewable electricity installations in the United States (excluding hydropower) have nearly tripled, and in 2008 represent 42 GW of installed capacity. • Wind and solar PV are the fastest growing renewable energy sectors. In 2008, wind capacity installations increased by 51% and solar PV grew 44% from the previous year. © 2010 Balance Energy All Rights Reserved
  4. 4. Transmission Difficult to Site Apr 4, 2010 - Chicago Tribune • The key challenge facing developers is that existing transmission lines, substations and transformers are inadequate to handle the amount of energy expected to come from wind farms • "It's easy to be green and say let's build wind but we have to think about - how are we going to deliver that?" said Thomas O'Neill, chief operating officer at Chicago-based Exelon Transmission Co., a unit of Exelon Corp. • The estimated cost to move that wind power east could range from $64 billion to $93 billion in 2009 dollars and would require 17,000 to 22,000 miles of transmission lines to be built in the eastern half of the country alone, according to National Renewable Energy Laboratory. • It isn't feasible for businesses to pay costs associated with the transmission upgrades. Many withdraw their requests to hook in once they realize the significant upgrades that would be needed, according to Midwest ISO. © 2010 Balance Energy All Rights Reserved

  10. 10. Pending Legislation Referencing Microgrids • H. R. 5230 - Mesa Act: The term `microgrid' means an integrated energy system consisting of interconnected loads and distributed energy resources (including generators, energy storage devices, and smart controls) that can operate with the utility grid or in an intentional islanding mode. © 2010 Balance Energy All Rights Reserved

  17. 17. Summary • MicroGrids allow generation, storage, and loads to operate autonomously, balancing out voltage and frequency issues. • MicroGrids facilitate parallel placement of small generation, storage, and load devices in a modular manner that scale up to higher levels. • Current weak link is cost-competitive storage. Some larger MicroGrids are using thermal storage, but electrical storage remains a key need. • As with Demand Response and Distributed Generation, Distributed Storage becomes a new market opportunity. • Commercial MicroGrids are a viable business opportunity, but the Utility remains very interested in their emergence and potential critical mass. © 2010 Balance Energy All Rights Reserved
