On April 30, 2018  Alaska Energy Authority (AEA) submitted the Notice of Intent to Continue with additional funds from the EPA under the Diesel Emission Reduction Act (DERA) program.  AEA portion is $411,150 of new federal funding with AEA  contributing $137,050 from the Rural Power System Upgrade Program, and the Volkswagen Settlement $274,100 (pending approval) for a total additional budget of $822,300.  This project, expanded with the FY17 funds, is expected to replace eight diesel engines and generators (where needed) in four rural powerhouses.

On October 1, 2017 Alaska Energy Authority (AEA) received $335,024 from the EPA under the Diesel Emission Reduction Act (DERA) and AEA is contributing $362,942 from the Rural Power System Upgrade Program as well as an additional contribution from the Denali Commission of $53,234  for a total project budget of $751,200.  This project is expected to replace four to six generators in rural powerhouses.  The community determination is on-going.

What is the project?

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.  These projects were expanded with local match, value engineering, and additional state funding to replace six diesel engines with five efficient, cleaner engines. 


Hughes DERA Project            
   


The scope of the 2017 Hughes DERA project consisted of:

1) Replacement of one existing 78kW non-Tier diesel engine with a new 100kW Tier 3 marine diesel engine.

2) Replacement of two existing 37kW non-Tier diesel engines with a new 165kW  Tier 2 marine diesel engine along with a
    new generator and skid (complete genset).

3) Permanently disabling the three old engines by cutting a minimum 3” hole in the block to prevent future operation.

4) Modification of existing exhaust, coolant, fuel, and other related systems as required to ensure proper operation of the new
    engines.

5) Installation of new power and control wiring for the new engines and generators.

6) Revisions to the generation controls and SCADA to ensure proper control and monitoring of engine and generator function. 
    Note that modifications were set up to
allow future conversion from single phase to three phase operation by others under
   
a separate project.

The Hughes project was completed 9/30/2017.
 

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?
Installing newer certified, more efficient engines will both reduce the emissions per quantity of fuel combusted, as well as produce electricity more efficiently further reducing emissions, as well as saving money. Specific estimates for each community are included in the workplan.
 

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.

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.

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.
