The Hakai Beach Institute microgrid is the off-grid solar-battery-diesel system at what is now Hakai Institute's Calvert Coastal Observatory in Pruth Bay on Calvert Island, British Columbia. The owner currently describes about 450 PV modules totaling roughly 150 kW, approximately 240 kWh of battery storage, one 72 kW normal-operation diesel generator, a second 72 kW backup, and a 12 kW core-load backup. This is a major expansion from the 30-50 kW PV configurations documented around its 2011 commissioning.

Research status
Operating. Hakai Institute's current technology page says the solar array can power the entire site under favorable conditions and charges the battery with surplus energy. The latest quantified fuel outcome found is historical: a 2016 owner article said diesel use had fallen below 20% of the pre-project level despite added buildings. Current annual renewable share, diesel liters, battery state of health, and generator runtime are not publicly reported.

Project delivery

Who was involved in Hakai Institute Microgrid?

5 publicly identified organizations. Where a recovered source named a participant without explaining its work, the role remains explicitly unspecified.

Organization

Canadian Solar

PV module supplier identified in the SMA monitoring record for the early 50 kWp phase. [6]

Organization

Hakai Energy Solutions

System designer/integrator formed from the team that rebuilt the site's electrical system; now independent but continuing to work with Hakai Institute. [4][3]

Organization

Hakai Institute / Tula Foundation

Research-station owner and current operator; the Tula Foundation acquired the former resort site in 2009 and developed the Calvert Island observatory. [2][3]

Organization

SMA

Publicly named participant; role not specified in the recovered record [1]

Organization

SMA Solar Technology

Supplier of the early-phase Sunny Island battery inverters, Sunny Boy PV inverters, and Multicluster controls documented for the 2011 system. [5][6]

Energy mix, capacity, and specifications

Values can describe different project phases, generation sources, storage systems, or other components. Source citations are attached to each figure so discrepancies remain visible.

KW Solar
53 [1]
KW Gas/Diesel
55 [1]
Current solar PV
Approximately 450 modules and about 150 kW total capacity [2]
Current battery storage
Approximately 240 kWh; chemistry, battery power, manufacturer, and model are not stated on Hakai Institute's current page [2]
Current diesel generation
One 72 kW unit supplements normal operation, a second 72 kW unit is maintenance/backup reserve, and a 12 kW unit can support core systems [2]
2011 initial expansion
Hakai Energy describes a three-phase modular inverter system, 50 kW PV, and battery storage; daily diesel fell from as much as 500 liters before 2010 to less than 100 liters by 2011 [4]
Early SMA published configuration
SMA's off-grid guide lists 30 kWp PV, 63 kW battery-inverter power, 250 kWh storage, and 55 kW diesel; its monitoring portal separately labels the commissioned plant 50 kWp with a 72 kW diesel. These are early-phase/vendor records and are not substituted for the current 150 kW/240 kWh owner figures. [5][6]
Historical diesel reduction
Less than 20% of the former diesel use after implementation, according to Hakai Institute's 2016 retrospective, despite additional buildings and research infrastructure [3]

Controls and hardware

Equipment and controller details

Manufacturer and model are shown only when a source names them. Generic descriptions are not converted into guessed product assignments.

01

Current PV array

Model not publicly disclosed

Approximately 450 modules/150 kW. Current module and inverter manufacturers/models are not identified; Canadian Solar modules and SMA inverters belong to the documented early phase and should not automatically be assigned to every later expansion. [2][6]

02

Early battery inverter cluster

SMA Solar Technology — Nine Sunny Island SI 6048-US with one Multicluster Box MCB-12U

SMA's published early configuration provided 63 kW of battery-inverter power. It is not confirmed as the complete current inverter fleet after the solar expansion. [5]

03

Early PV inverters

SMA Solar Technology — Six Sunny Boy SB 5000-US

Documented in SMA's 30 kWp system guide; the separate SMA portal records a 50 kWp early plant. Current expansion equipment is undisclosed. [5][6]

04

Early PV modules

Canadian Solar — CS6P-220P

Module type shown in the SMA monitoring portal for the 2011 plant; no evidence reviewed confirms that all roughly 450 present modules use this model. [6]

05

Diesel generators

Model not publicly disclosed

Current owner page gives 72 kW + 72 kW + 12 kW roles but not manufacturers or models. Generator heat recovery was incorporated in the early system to serve heating loads. [2][4]

Technical record

Architecture, performance, and project updates

Concise technical facts, milestones, operating results, and later developments. Dated notes distinguish historical design claims from current evidence.

  • Off-grid architecture

    The Calvert Island research station has no utility interconnection. Solar directly serves site loads, excess charges the battery, and dispatchable diesel fills renewable/energy deficits; multiple generators provide operational and core-load redundancy. [2][5]

  • Demand and thermal integration

    The original retrofit included demand-side management and recovered generator heat for building heating. Site growth continued while fuel consumption fell, so simple capacity comparisons across the 2011 and current phases do not represent an unchanged load. [4][3]

  • Capacity evolution

    SMA documented an early 30 kWp configuration and portal metadata labels 50 kWp; Hakai Energy likewise describes 50 kW by 2011; the current owner page reports about 150 kW. These are expansion stages, not three simultaneous PV plants. [5][6][4][2]

  • Fuel performance

    Hakai Energy reports pre-2010 fuel use of up to 500 L/day and under 100 L/day by 2011. Hakai Institute's 2016 retrospective reports less than 20% of former diesel use. Neither is a current audited energy mix, and no annual solar-generation series was found. [4][3]

  • Location clarification

    The electrical system is at the Calvert Coastal Observatory in Pruth Bay on Calvert Island. Hakai Institute also operates instruments across nearby Hecate Island, but that does not make Hecate Island the microgrid site. [2]

  • Evidence quality warning

    The public SMA portal's annual-production metadata is implausibly large for a 50 kWp plant and is excluded. Current storage chemistry, inverter fleet, PV module models, generator makes, measured renewable fraction, and state-of-health remain undisclosed. [6][2]
