Power Cost Equalization has been a topic of great interest in the news recently, with a variety of opinions expressed about the $1 billion endowment fund that provides PCE funding. The Alaska Energy Authority administers this program, which reduces the high cost of electricity in rural Alaska for residential and community facility customers. The program serves 84,000 Alaskans in 194 communities that are largely reliant on diesel fuel for power generation. In fiscal 2018, these rural customers received over $26 million in PCE payments.
PCE is one of many programs and projects AEA manages for the benefit of Alaskans. Whether building modern and code-compliant bulk fuel tank farms, upgrading to high-efficiency generators in rural powerhouse systems, or integrating renewable energy projects, AEA emphasizes community-based project management. AEA’s core programs work to diversify Alaska’s energy portfolio, lead energy planning and policy, invest in Alaska’s energy infrastructure, and provide rural Alaska with technical and community assistance.
Another AEA project, Bradley Lake Hydro, is a 120 megawatt hydroelectric facility located at the east end of Kachemak Bay, near Homer. Bradley Lake is the largest renewable energy project in Alaska and provides some of the cheapest power on the Railbelt Grid at approximately 4.5 cents per kilowatt hour. This power is shared between the Railbelt utilities and meets from 8%-10% of total Railbelt demand.
The Bradley Lake project is so valuable to Alaska that AEA and its Railbelt utility partners decided in 2017 to increase Bradley Lake generation by building the Battle Creek diversion. That project, currently in construction, will divert water from the upper Battle Creek into Bradley Lake. It will cost $48 million and increase Bradley Lake hydro output by about 10%. AEA financed the Battle Creek project with bonds including New Clean Renewable Energy Bonds and Qualified Energy Conservation Bonds, saving the Railbelt utilities about $20 million in financing costs.
AEA owns another major Railbelt electric project: the Alaska Intertie, a 170-mile transmission line between Willow and Healy. It provides a critical link between Southcentral utilities and Golden Valley Electric Association in Fairbanks. The intertie primarily carries relatively cheap Bradley Lake and natural gas-fired power to GVEA. This allows GVEA to reduce its consumption of more expensive fuel oil and the associated emissions. It also allows GVEA to provide spinning reserve and other benefits to Southcentral utilities.
AEA funds and constructs energy projects in rural Alaska as well. Since 2000, AEA has constructed or upgraded more than 100 bulk fuel projects in rural Alaska. Most of these were consolidated village tank farm projects funded in part by the Denali Commission. With Denali Commission and state funding, AEA has constructed or upgraded more than 80 powerhouses in rural Alaska. Many of these projects incorporate technological advances such as modular powerhouse construction, marine manifolds on diesel engines to maximize heat recovery, and used-oil blending systems to reduce cost and the risk of environmental contamination.
Since 2008, AEA’s Renewable Energy Fund has awarded more than $250 million in state funds for renewable energy projects. These range from solar photovoltaic modules in Kaltag, to seawater heat pumps in Seward. Kodiak Electric Association’s success with its REF-funded wind and hydro projects has attracted international attention, and helped the utility achieve its goal of generating more than 98% of its power from renewable energy.
From PCE, to renewable energy, to management of its critical energy infrastructure, AEA provides benefit to Alaskans across a broad spectrum of energy technologies and policies. It is imperative that Alaska continues to pursue energy projects that will provide sustainable, affordable power, which is the backbone of economic development and healthy communities.
