Alaska Energy Authority Renewable Energy Fund
ACEP, with oversight from the AEA, collaborated with selected AEA REF grant recipients to analyze project impacts.
ACEP project activities include the following:
- Technical assistance to grant recipients with instrumentation specification, installation, integration, and configuration to collect the data points specified by the data collection plan.
- Automated standard (non-interpretive) monthly reports for AEA and the grant recipient that will include aggregated plots and summaries of specific data collected as well as appropriate statistical measures.
- Open access to the data, if permitted, via the Alaska Energy Data Gateway that will allow data to be ordered and/or processed into a graphical and easy-to-understand format for AEA and other public users.
- Site visits to review and support data collection activities.
- Independent analysis of data at project completion to verify project results, energy production, and savings.
Chevak - Excess Wind-to-Heat and Waste Heat Recovery from Diesel Generators in the Community Powerhouse
(Project Report: Chevak REF Round 5 and Round 7)
- (1) Performance assessment of wind turbines (i.e., are the wind turbines operating to capacity, when are they curtailed, etc.?);
- (2) Quantification of excess wind diverted to the community’s water plant system and associated fuel savings;
- (3) Delivery system losses for recovered heat, and associated fuel savings from recovered heat system.
- (4) Assessment of additional wind power available for diversion into demand managed thermal loads to offset further heating fuel requirements and increase utility revenue.
Eagle and Eagle Village - Community Solar Array
- (1) What are peak solar ramp rates, when do they occur, and do they impact reliability?
- (2) Does the solar project impact frequency of blackouts, for example at high solar penetration if the Eagle Village intertie goes down?
- (3) Are there power quality impacts caused by integration of the solar array?
- (4) How does the project performance compare to PVWatts predictions?
Nome - Wind Turbine Impacts on Community Energy Sources
(Project Report: Nome Wind-Diesel System Overview)
- (1) Automated emissions reporting to facilitate air quality permitting requirements.
- (2) Impact of wind utilization on diesel fuel efficiencies to determine more accurate diesel offset when engine efficiencies are reduced at low loads.
- (3) Tracking of excess wind and power to determine potential for system optimization and maximum use of renewables
