Diesel Emission Reduction Act (DERA)

In 2016 Alaska Energy Authority (AEA) received $286,241 from the EPA under the Diesel Emission Reduction Act (DERA) and AEA is contributing $310,094 from the Rural Power System Upgrade Program as well as an additional contribution from the Denali Commission of $152,874  for a total project budget of $749,209.  This project is expected to replace five generators with four generators in three rural communities.

In 2015 AEA partnered with the Division of Environmental Conservation (DEC). DEC received $248,212 from EPA under the Diesel Emission Reduction Act (DERA) and AEA is contributing $235,652, for a total project budget of $483,864 to replace four diesel generators in four rural communities: Chuathbaluk, Crooked Creek, Sleetmute, and Stony River.

What is the project?

In the spring of 2016 AEA replaced four diesel engines in the power plants of four Alaskan rural communities: Chuathbaluk, Crooked Creek, Sleetmute and Stony River.  With support of this DERA grant, these non-certified, mechanically controlled engines were upgraded to marine certified Tier 2 and Tier 3 electronically controlled engines, improving efficiency and lowering emissions.  The project was completed with the final installations and testing completed in September 2016.

Chuathbaluk Replacement Engines


Why is this project important?

In rural Alaska, communities are not connected to the electric grid so they must generate power locally.  Small diesel power plants are used in small rural communities across the state. Emissions from these engines can be problematic and inefficient engines drive up fuel consumption and power costs.

What are the estimated environmental/economic benefits?

The project is expected to reduce diesel emissions from the four engines with the following:

    • Yearly reductions: 6.35 tons of NOx, 0.21 tons of PM, 5.1 tons of CO, and 913 tons of CO2.
    • 20-year lifetime reductions: 126.7 tons of NOx, 4.09 tons of PM, 102.2 tons of CO, and 18255 tons of CO2.


Moving Forward

EPA approved a request by DEC for AEA to be the lead granting authority for Alaska to administer funds from the DERA program starting fiscal year 2016.  DEC will continuing to provide assistance to AEA on the air quality measures associated with any DERA funding, and any other assistance they may need to manage these funds.

Previous DERA, ARRA, & Misc. Diesel Projects 

Alaska Department of Environmental Conservation (ADEC) funded several projects to reduce emissions from a variety of sources all over Alaska. Projects included retrofitting of school busses, power plants and diesel garbage trucks, purchase and transport of biodiesel to Denali National Park and engine idle reduction. For more information about DERA funding opportunities for cities and tribes click here:  https://www.epa.gov/cleandiesel

ADEC was awarded funding from Environmental Protection Agency (EPA) via the American Recovery and Investment Act of 2009 (ARRA) and Diesel Emission Reduction Act (DERA) under the National Clean Diesel Campaign. The funding allowed the State of Alaska to "lead by example" and retrofit and replace vehicles operated and maintained by the Alaska department of Transportation and Alaska Railroad. Alaska Energy Authority received funding to test and implement green engine for power generation in rural Alaska.

In addition to the state agencies, the ARRA and DERA funding was extended to private organization through request for proposal. Alaska Village Electric Cooperative (AVEC) was awarded a grant to reduce diesel fuel usage in remote areas of Alaska through heat recovery systems.

Listed below are all the projects that were undertaken by ADEC and the partnered agencies/organizations. Some of the projects are completed and some are on the way to completion.
