Host: The U.S. Department of Energy (DOE) Office of Indian Energy Policy and Programs, Office of Energy Efficiency and Renewable Energy Tribal Energy Program, and Western Area Power Administration are pleased to continue their sponsorship of the Tribal Renewable Energy Webinar Series.
Introductory Summary: The development of more renewable energy resources raises challenges and opportunities for the electric grid relating to upgrades and potential new construction. This webinar addresses the components needed to analyze and assess the impacts, costs, and benefits of transmission line upgrades and additions. The series is designed to promote energy efficiency and foster economic development and overcome barriers to Indian independent through electrification of Indian’s homes.
Speaker: Ed Weber, Sr. Electrical Engineer
Power Project Evaluation Studies: The history of how evaluate the gird through FERC (Federal Energy Regulatory Commission, the ruling body of the grid). The rate-based concept ran the grid. FERC approved the wholesale rates to achieve reliable service to the loads. FERC Order 88 changed to market based rates. Since ENRON FERC has strengthened market regulation. Now a transmission service agreement is required to move power in either a Network or Point-to-Point service. The current load growth and coal plant retirement due to aging generators is being answered by increased capacity in natural gas, growth in solar and new transmission projects. Wind growth has slowed since 2008. Barriers to growth are environmental concerns and financing. Current transmission plants are not near load centers.
Propose a project: that replaces energy transmission loss (such as a closing coal plant) and that has the natural resources that you need. The Right of Way (ROW) and Environmental Studies, Tribal land use requirements need to be addressed. Equipment procurement has a 18-24 month lead time.
Speaker: Gail Mansell, Transmission System Planning Mgr.
Generation Interconnection Requests: identify interconnection problems. She explains the general interconnection requirements, fees and procedures. Tariff documents for Nevada and N Nevada are available at OASIS (https://www.nvenergy.com/company/rates/). The Interconnection Studies look at Overload, Low Voltage, Transient Stability, Short Circuit Stability. The point is to show that the new transmission system will not degrade the capability of the existing system.
Summary: The key is reliability. Current 10% return on investment makes the transmission projects attractive. Coal plant closing is the major driver so propose a project to replace that energy source. The future looks like a combination of solar and wind farms. The Interconnection Studies are “First paid – First studied” so it looks like the bias is toward those that already have money.
