Small Hydropower

Small hydroelectric generation is a renewable and decentralized source of electricity, which is typically employed with very minimal environmental impact. Unlike large hydroelectric projects requiring the damming of rivers, small hydro projects simply divert a portion of a river or creek’s flow or are constructed on pre-existing diversions, such as raw water distribution systems. Such systems have been in use for over a century and in many places and were the original source of electricity. In fact, the world's first commercial-grade alternating-current power plant was built in Colorado in 1891 by L.L. Nunn, Nikola Tesla and George Westinghouse.

Small Hydro Streamlined Federal Permitting Project


In 35 years, only 26 federal permits have been issued for hydropower projects in Colorado. The CEO has received significant national attention for pioneering partnership efforts with the federal government to address barriers to hydropower development. Currently, hydropower is only renewable energy technology that requires a permit from the federal government to operate. CEO’s Small Hydro Permitting Process assists developers of small, low-impact hydropower projects in applying for a federal permit. This effort saves time and money for hydropower developers and lowers the risk in investing in hydropower in Colorado. Projects that qualify for assistance under this program must use existing infrastructure and have very low potential impacts on the environment.

 


 

Case Study: The Meeker Wenschhof Project

 

 

The Meeker Wenschhof project in Rio Blanco County is a 23 kW small hydropower project that will utilize water historically used for irrigation to produce power that will offset the electricity consumption of a water-saving irrigation sprinkler. This low impact project provides a rural Colorado rancher new revenue in the form of electricity savings, and is easy to duplicate, providing other ranchers in the state an avenue to replicate the project and associated savings.

 

How the Colorado Energy Office helped make this project a reality

In 2010 the state of Colorado signed a Memorandum of Understanding with The Federal Energy Regulatory Commission (FERC) to streamline the permitting process, leading the nation in an effort to make small hydropower permits more economical and accessible. This created an avenue for the Colorado Energy Office (CEO) to create the Renewable Energy Development Team (REDT) and help move projects toward success. The REDT helps identify Colorado renewable energy projects with the best potential for development and provides them with the technical and business development assistance needed to help move the projects beyond the typical hurtles and barriers that can significantly delay or kill projects.

 

Project Details:

Site Location: Meeker, Colorado
Project Capacity: 23kW
Annual Generation: 100,000kWh
Installed Costs: $140,000
Project Savings: $350,000


 


 

Barrier: The FERC permitting process for hydropower projects is complex, expensive and prohibitive for most who wish to develop a small hydro operation. In 35 years, only 26 federal permits have been issued for hydropower projects in Colorado. Before an application can be submitted to FERC it undergoes review by multiple regulatory agencies. The process typically takes several years because some regulatory agencies do not begin their review until another agency’s review is complete. Following the regulatory agency review process, FERC’s own review can take an additional two to three years. The combined regulatory agency and FERC reviews can potentially delay projects five to six years, or derail them entirely due to the added costs.

 

How CEO helped: CEO’s REDT essentially “stacked” multiple regulatory agency reviews to occur simultaneously, trimming the time it took to complete the pre-FERC application review from several years down to months. A single REDT point of contact helps FERC and the other regulatory agencies know that the applications are complete and consistent, removing the uncertainty that can cause the lengthy delays. In July, CEO’s REDT successfully submitted its first hydropower conduit exemption application to FERC and it was approved in just two months, a significant reduction over a process that historically took up to three years. 

 


 

Barrier: The rural rancher had a great idea to use existing water power on his own property to power his entire ranch, but he needed help to determine whether his project was economically viable.

 

How CEO helped: The REDT used financial modeling tools to help the rancher understand that his project was economically viable and encouraged him to proceed.

 


 

Barrier: 1603 federal grants have not typically been available to projects such as this one because the classification criteria for small projects are convoluted. 

 

How CEO helped: The REDT made a successful case to submit this project for a 30% federal grant. REDT secured a letter of support from CEO, expert opinions, and a meeting with grant administrators to obtain clear direction. This success establishes a new precedent and a clear classification path, which creates new opportunities for similar projects that hope to obtain a grant.

 


 

Barrier: Once the project was viable, the rancher needed assistance to counter a small, rural bank’s resistance to a renewable energy project loan. The bank lacked experience with renewable energy projects and was reluctant to move forward without credible information.

 

How CEO helped: The REDT talked to the rancher’s bank to answer project questions and this helped secure the needed construction financing.

 


 

Results

  • The Meeker Wenschhof project became the first hydro project in the nation to go through the new FERC streamlined process and receive a conduit exemption, doing so in just two months.

  • The project will save this rural Colorado rancher $350,000 in utility costs over 30 years.

  • The rancher will be able to offset 100% of his ranch’s electrical load.

  • The rancher is able to utilize a 30% federal grant that previously would not be available to projects like his.
