Alaska Energy Authority Renewable Energy Fund — Data Oversight
A robust data management program for the Alaska Energy Authority’s (AEA) Renewable Energy Fund (REF) project is critical to defining success for both individual projects and the program as a whole. For selected REF projects, as identified by AEA, the Alaska Center for Energy and Power (ACEP) is providing data oversight services and ensuring that accurate and appropriate performance data is being collected by grant recipients so that a project’s effectiveness can be accurately measured.
ACEP, with oversight from the AEA, is collaborating with selected AEA REF grant recipients to develop data collection plans. ACEP will be responsible for overseeing the execution of the data collection plans and for providing data management services such as data storage, quality assurance, archiving, and reporting for AEA’s benefit.
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
- (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
- (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
ACEP is currently working with the AEA and the Institute for Social and Economic Research (ISER) to build on the previous Alaska Energy Data Gateway effort between the
two entities, which was formerly funded under a Department of Energy EPSCoR (Experimental Program to Stimulate Competitive Research) initiative. This effort will enable
the dissemination of high-quality, technical data and reporting supported by the data collection plans. ACEP will showcase its data collection and management infrastructure using currently funded REF projects to be determined by AEA.
