We lookforward to seeing you!Mahalo,Dr. Karl E. StahlkopfSenior Vice President of EnergySolutions and ChiefTechnology OfficerEnergy EfficiencyTakes-Off at theHonolulu InternationalAirportAs part of a bold and strategic energy plan that encourages and supportsmarket-based development of reliable, cost-effective, and self-reliant energy forHawai’i, Governor Linda Lingle issued Administrative Directive No. 06-01(Energy and Resource Efficiency and Renewable Energy and ResourceDevelopment) in January 20, 2006. This directive states in part that Stateagencies must assess their practices and programs to reduce energy use inorder to establish a secure energy and economic future for the people ofHawai’i. Honolulu International Airport, one of the most energy-intensivefacilities on the island of Oahu was the first State of Hawai’i – Department ofTransportation (DOT) Airports Division’s facility to take action towardssaving energy, cutting costs, and improving its sustainability. With $4 millionin funds, energy efficiency projects tookoff in 2007 with the replacement of theairfield taxiway light fixtures andguidance signs.Taking advantage of the increasedperformance and lowered cost ofhigh-intensity Lighting Emitting Diode(LED) technology, the DOT AirportsDivision’s team of engineers wereable to replace all of the 30-wattincandescent taxiway lamps with 1-watt high-intensity LED lamps. Along withthe lamps, the 30/45-watt isolation transformers were also replaced with lowerwattage more efficient transformers. Each taxiway light fixture uses an isolationtransformer to isolate low-voltage in the lamp from the high operating voltagepresent on the airfield series of lighting circuits. When one of the lamps fails,the isolation transformer plays a key role in helping to prevent the interruptionof power to the remaining loads.2

The overall wattage reduction for theentire taxiway lighting system (lampand isolation transformer) wasestimated to be 36-watt per fixture.This is based upon efficiencies listedunder the Siemens Elevated TaxiwayEdge Light product specifications. Withthe retrofit of 1755 taxiway lights andisolation transformers, HonoluluInternational Airport was able to achievea reduction in energy consumptionof nearly 300,000 kWh per year andsavings of more than $27,000 on theirannual electric bill. In addition to theenergy and dollar savings, HawaiianElectric Company, Inc. (HECO)Energy$olutions SM for Business programprovided a customized rebate ofover $19,000.Benefits from using this new class ofhigh-intensity LED comes from theextensive lifetime of the lamp. TheSiemens Signature SeriesL-861T LED Elevated Taxiway Edge LightLEDs used in the taxiway light fixturesat Honolulu International Airport havean average life of 100,000 hours underhigh-intensity conditions and more than200,000 hours under actual operatingconditions. With a far greater lifeexpectancy than conventionalincandescent lamps (i.e., 1000 hours),there is a significant potential for savingsin both maintenance costs as well asreduction in operational disruptions.Additional energy efficiency measuresimplemented at the airport were theretrofitting of 286 guidance signs. Themain purpose of these signs is to guidepilots to a particular point on theairfield, identify holding positions,identify taxiway and runwayintersections, and prohibit aircraft entryinto designated areas. The oldguidance signs, internally illuminatedby two or more 50-watt high-pressuresodium (HPS) lamps, were replaced withnew Siemens’ Signature Series guidancesigns, which use 18-watt pin mountcompact fluorescent lamps (CFLs). Eachnew guidance sign is made of two tofour modules containing two lamps permodule, thus the total number of CFLlamps installed for 286 guidance signs is1422 CFLs.As a result of these new energy efficientguidance signs replacement, HonoluluInternational Airport saved anadditional 300,000 kWh in energyconsumption per year and received astandard rebate of over $14,000 underHECO’s Energy$olutions SM for Businessprogram. The CFL provides a moreuniform distribution of light, makingguidance signs more readable.The next energy efficiency “arrival”from Honolulu International Airport isthe replacement and relocation of theDiamond Head Chiller Plant. The newchiller plant will have the capability toair-condition the entire airport whilethe Ewa and Overseas/Main TerminalChiller Plants undergo separaterenovations. In fact, the three chillerplants will be consolidated into one centralplant. This project is already on itsway and it will be the subject of a futurePowerlines publication.Energy Savings Highlights:Annual Savings $54,000Annual kWh Reduction 600,000HECO Rebates $33,0003

Hawai’i is highly dependent on imported fuel forits energy and transportation needs. In 2008, theUS has seen energy pricing rise to record levelswith oil prices breaking the $100/barrel threshold.As a result, gasoline prices have increased and thecost to drive a car to work, school, or the store isbecoming a significant monthly expense. Withless available spending money, many localresidents are forced to control their spendingand cut costs to cope with a higher cost of living.Energy conservation is becoming more important.People are planning their trips to the store morecarefully. Some are carpooling or taking masstransit alternatives. Others are considering buyinga fuel efficient hybrid rather than a large SUV. Inthe home, compact fluorescent lamps (CFLs) arereplacing incandescent light bulbs. Openwindows or fans are cooling homes instead ofrunning the air conditioning units.Energy Efficiency Tipsto help LowerEnergy Bill and Benefit theEnvironmentRising fuel costs, higher operating expenses andincreasing concerns of global warming haveprompted many large companies to focus onenergy conservation through energy efficiencyimprovements as one way to control expensesand improve profits. These companies realize thatenergy efficiency improvements are the only wayto control energy costs. With energy prices risingeach year and increasing concerns of globalwarming from carbon emissions, efficiencyimprovements and energy conservation measuresare the least-cost options to managing energycosts. Hawaiian Electric Company, Inc. (HECO)and its subsidiaries Hawaii Electric Light Company(HELCO) and Maui Electric Company (MECO)are supportive of energy efficiency improvementsby providing rebate programs for localbusinesses and residents. Since the launch ofHECO’s Energy$olutions SM for Business rebateprograms, over $27 million dollars have been paidto customers who have implemented energyefficiency improvements. Energy efficiency saved402 million kilowatt hours of energy or almost670,000 barrels of oil that would have been usedby our power plants every year.4

energy efficiency & conservation improvementsTo assist local businesses and residents, HECO has compiled the top ten lists of energy efficiency / conservation improvementsfor businesses and homes:No. Commercial Residential1 Upgrade interior and exterior lighting to more energyefficient fixtures. Replace standard incandescentlight bulbs and consider compact fluorescent lamps(CFLs), T-8, and T-5 lamps.2 Upgrade existing air conditioning systems to moreenergy efficient equipment.3 Install or replace old motors with premium efficiencymotors and variable frequency drives.4 Install solar water heating system or electronic heatpump to heat water.Install a solar water heating system or a high efficiencyelectric water heater.Replace standard incandescent light bulbs with newenergy efficient compact fluorescent lamp (CFL) bulbs.Replace existing shower heads with new low flow unitswhich use less hot water.Turn down the thermostat on your electric water heaterto 120° Fahrenheit.5 Install occupancy sensors for 24 hour lighting areas. Use the sun to dry clothes instead of using the electricdryer.6 Consider Demand Control Ventilation (DCV) systemsto adjust and control outside airflow to match currentbuilding needs.7 Consider energy management systems to controlair conditioning, ventilation, and lighting systems tooperate equipment only when necessary and avoidrunning equipment unnecessarily.Turn off lights or electronic equipment like televisionswhen leaving the room.Install new energy efficient “Energy Star” Appliances.8 Consider window tinting. Install occupancy sensors indoors and outdoors(security lights).9 Consider daylighting systems with lighting controls toilluminate a room or office.10 Consider supply air reset techniques and controls toadjust supply air temperature setpoints during lowoccupancy periods.Use a power strip to conveniently turn off electronicequipment for cell phones, printers, DVD players, VCRs,televisions, radios, and other electronic equipment thatis not being used.Shut-off computers and monitors when leaving theroom for more than 20 minutes.For more information on these and other energy solutions, commercial and residential customers can contact HECO at94-POWER or visit our website at www.heco.com.5

Focus on Safety: GFCIs & AFCIsVarious Types ofGround-Fault Circuit-InterruptersThe ground-fault circuit-interrupters(GFCIs) and arc-fault circuit-interrupters (AFCIs) are two differentelectrical devices that serve distinctpurposes. A GFCI is designed toprevent electrical shock. It has beenestimated that if GFCIs are installed inhousehold branch circuits, they couldprevent about two-thirds of theapproximately 300 accidentalelectrocutions that happen in andaround the home each year. 1Likewise, AFCIs could save lives as wellas prevent property loss through theiruse and installation. In this article wewill discuss:• How GFCIs work and why they areimportant• How AFCIs work and why they areimportant• Code issues concerning GFCIs andAFCIs1www.cpsc.gov/cpscpub/pubs/99.html, ConsumerProduct Safety Commission, GFCIs Fact Sheet, 1996.2Ibid.Ground-Fault Circuit-Interrupters (GFCIs)A GFCI is a device that interrupts an electrical circuit when a ground-faultis detected. It is specifically designed to prevent electric shock when aperson comes into contact with an electrically energized part. The deviceis only applicable for 120-volt, single-phase circuits. The GFCI operates bycomparing the current between the hot path to the load (an appliance orlight, for example) and the neutral or return path. If an imbalance as littleas 5 milliamps exists for a period as short as 2 cycles (33 milliseconds), thedevice will trip the circuit. A current imbalance condition between the hotand neutral path indicates a ground fault wherein current is somehowbeing diverted to a ground path. 2 An example of a shock hazard conditioninvolving a ground fault would be if someone were standing barefoot ona wet concrete floor and coming into contact with an extension cord withbroken insulation that exposing bare live wire. As one can surmise fromthis example, a GFCI at the electric receptacle where the cord is plugged incould be lifesaving. For older homes with 2-wire 125-volt receptacles, theinstallation of a GFCI receptacle or plug-in module will still protect againstground-faults.GFCIs are available as either receptacles (they are now required by code inbathrooms, kitchens, basements, garages, and other places where watermay be present), plug–in modules for use with power tools, and part of thecord-plug combination of certain appliance such as hair dryers and circuitbreakers. GFCIs include test/reset pushbuttons and these devices should betested after installation and monthly according to Underwriters Laboratory.6

Code Issues Concerning GFCIs and AFCIsArc-Fault Circuit-Interrupters(AFCIs)An AFCI is a device that interrupts an electricalcircuit when an arcing fault is detected. Itis specifically designed to prevent a fire whenan arcing current is detected. The deviceis only applicable for 120-volt, single-phasecircuits. The device works by tripping theprotected circuit when a waveform typical ofan arc-fault current is detected. It can distinguishbetween inrush current, arcing currentwhen a switch is in operation, and the kindof unintended arcing current that can posea fire hazard. These types of hazardous arcscan occur at loose connections and terminationsor where wire insulation has becomedamaged. 3AFCIs are available as circuit breakers and alsoinclude a test pushbutton. As with GFCIs,AFCIs should be tested after they are installedas well as once per month. CombinationGFCI-AFCI circuit breakers are also available. 4Arc-Fault Circuit-Interrupter Circuit BreakersMost municipalities, including Hawai’i, require that the installation of electricalsystems within residential and commercial buildings follow NationalElectric Code (NEC) requirements. Article 210 of the NEC governs therequirements for GFCI and AFCI applications as they apply to branch circuitprotection.Section 210.8 of the NEC - Ground-Fault Circuit-Interrupter Protectionfor Personnel - covers the GFCI requirements for residential dwelling unitsand commercial buildings. Section 210.8 (A) lists the specific locationsin dwelling units where GFCI branch circuit protection is required. Theselocations include bathrooms, garages, outdoors, crawl spaces at or belowgrade, unfinished basements, kitchens, areas around laundry and wet barsinks, and boat houses. Section 210.8 (B) lists the specific locations incommercial buildings where GFCI branch circuit protection is required.These locations include bathrooms, commercial and institutional kitchens,rooftops, and outdoors in public places. These requirements apply tosingle-phase 125-volt receptacles rated at 15 amps or 20 amps. 5Section 210.12 of the NEC - Arc-Fault Circuit-Interrupter Protection – coversthe AFCI requirements for dwelling unit bedrooms, guest rooms andguest suites. These requirements apply to single-phase 120-volt branchcircuits rated at 15 amps or 20 amps. 6 AFCIs are required for bedroombranch circuits in new residential construction effective January 1, 2002.As of January 1, 2008 the NEC mandates that the “branch circuits supplyingoutlets installed in dwelling unit family rooms, dining rooms, livingrooms, parlors, libraries, dens, bedrooms, sun rooms, recreation rooms,closets, hallways, or similar rooms or areas shall be protected by a listedarc-fault circuit-interrupter, combination-type, installed to provide protectionof the branch circuit.” 7In addition to permanent installation requirements for GFCIs, there are occupationalsafety requirements governing the use of GFCIs. OSHA Regulations(Standards - 29 CFR) Section 1926.404(b)(1) mandates GFCI protectionof single-phase 120-volt 15 amps and 20 amps receptacle outlets atconstruction sites.Hawaii Administrative Rules Title 12 Subtitle 8 (Division of OccupationalSafety and Health) Part 2 Chapter 89.1 (Electrical) Section1910.304(b)(3)(i) covers GFCI branch circuit protection.3www.nfpa.org, National Fire Protection Association,Electrical Circuit-Interrupters, September2007.4www.cpsc.gov/CPSCPUB/PUBS/afcifac8.pdf,Consumer Product Safety Commission, Arc-FaultCircuit-Interrupter (AFCI) Fact Sheet, January2001.So when it comes to safety and fire prevention think of GFCIs and AFCIs!5National Electrical Code Committee, NFPA 70 National Electrical Code 2005 Edition,National Fire Protection Association, 2004.6Ibid.7www.afcisafety.org/codes.html, National Electrical Manufacturers Association(NEMA), Arc-Fault Breaker Safety – Codes and Standards – 2008 NEC AFCI CodeLanguage.7

Surfers and swimmers remember never toturn their backs on the ocean. HawaiianElectric Company, Inc. (HECO) renewableenergy engineers and generationplanners have the same motto.With the surf pounding the shores allaround our islands, HECO has kept awatchful and hopeful eye on thepossibility of obtaining electric powerfrom this natural, renewable resource.But how to harness the obvious powerof the ocean to make electricity for ourhomes and businesses -- at a reasonablecost and without damage to ourenvironment -- has been the bigchallenge.For years, HECO has kept track of waveenergy development, sent representativesto international conferences, andconsulted with potential wave energydevelopers who have visited our islands.Like wind energy 15 or 20 years ago,many different technologies for oceanenergy are contendingfor commercial viability.The Ocean PowerTechnology buoy systemtested off Kaneohe MarineCorps Base is one ofthem. The Pelamis sea snake is another.Finally, HECO has found an excellentwave technology that engineers believemakes sense for Hawai’i and many otherplaces as well.It was developed by an Australia-basedinternational high-tech company calledOceanlinx, formerly Energetech. And inFebruary, at a meeting with GovernorLinda Lingle, Oceanlinx officials unveiledplans to provide electricity to MauiElectric Company (MECO) from Hawai’i’sfirst wave energy project.“This innovative and environmentallybased wave energy project is an idealexample of using Hawai’i’s abundantnatural sources of energy to reduce ourdependence on imported fossil fuel andincrease our energy security,” saidGovernor Lingle.“This is an historic occasion for Hawai’i,”said Mike May, HECO’s President andCEO.“Wave energy is more available andmore predictable than most other typesof renewable resources,” said OceanlinxExecutive Chairman and CEO DavidWeaver. “Commercial satellites allowlong-range tracking of wave patternsdays in advance. With such advanceddata, the utility is better able to plan forthe generation output of our unit.”“We are very pleased to be a part ofHawai’i’s move to increase its productionof electricity from clean energy sources,”he said. “The Oceanlinx technology is anMECO and OceanlinxPartner to HarnessWave Energy10

ideal fit for Maui, with its excellent waveclimate, and we hope to be able tocontinue working in Hawai’i onadditional wave energy projects in thefuture.”The plan is to provide up to 2.7megawatts from two to three floatingplatforms located in the waters due northof Pauwela Point on the northeast coastof Maui. If the first platforms performwell, Maui and other islands as well couldhost more. As they are moored half tothree quarters of a mile off shore, theirvisibility is quite limited, little more thana blip on the horizon, if that.(left to right): In the governor’s office, Dr. Peter Kalish and David Weaver ofOceanlinx, with Senator J. Kalani English, Representative Cynthia Thielen, HECOPresident and CEO Mike May, HECO Senior Vice President Karl Stahlkopf, andMECO President Ed Reinhardt.The northeast Maui site was picked for itsgood wave regime, proximity of the gridadjacent to the point, where a lighthouseformerly operated, and the absence ofboating and surfing activity in the area.Nearby “Jaws” surfing site is well out ofthe way of activity associated with theOceanlinx platforms.“In discussions with government andenvironmental leaders, we have heardnothing but strong support for thisproject,” said Ed Reinhardt, MECO’sPresident. MECO has held meetings withcommunity associations, boaters, fishers,and surfers, as well as with environmentalgroups like Maui Tomorrow and the Mauichapter of the Sierra Club.Oceanlinx will prepare an environmentalimpact statement for the project andwill apply for necessary permits andapprovals. In the future, the Oceanlinxplatform could also be used to desalinatewater, making it even more attractive fordrought-prone Maui.Oceanlinx’s innovative technologycombines the established science of theoscillating water column with a patentedturbine technology. Rising and falling seaswells push and pull air past the turbine.Key advantages of OceanlinxIncreased power output: The technology can be deployed in a variety of waterdepths including near shore and in offshore deep water where wave power levelsare higher.Low maintenance: The design has kept moving parts to a minimum and locatedthem above water, to minimize failure rates and reduce downtime. The stabilityof the platforms and accessibility from the deck of the rotating machinery allowsfor routine maintenance to be performed on location instead of requiring units tobe removed to dockside. The units contain a small number of rotating machineryparts, which are accessible from the deck of the unit minimizing the cost ofoperations and maintenance.Scalability: The modular design means that facilities can be scaled to meet theneeds of the customer by grouping multiple units into arrays. In addition, theunits themselves have a higher capacity rating than other wave energyalternatives.Mass production benefits: The units are modular in design and can bemanufactured using mass production techniques in standard fabrication facilitiesand shipyards. The topside modules can be factory assembled and then deliveredto the shipyard for integration, hook-up, and commissioning onto the marinestructure. This allows for the units to be pre-commissioned and tested beforeinstallation.Product diversification: Oceanlinx has also developed technology to use theenergy generated by the turbine to drive a desalination unit converting sea waterto fresh water using a reverse osmosis technique.Renewable energy and carbon credits: Both the generation of electricity and thedesalination of sea water to produce fresh water will qualify for renewable energyand/or carbon credits in most Oceanlinx target markets.11

The turbine’s blades shift in response tothe direction of the air flow, allowing theturbine to turn continuously in onedirection. Electricity is then broughtashore through an undersea cable andunderground lines to a substation tied tothe island electrical grid.Unlike many other kinds of wave energytechnology, the Oceanlinx system hasno moving parts below the water line,avoiding some of the tribulations thatvex boat owners everywhere, like thecorrosive nature of salt water and thelove of barnacles and the like to attach toanything in the water.Oceanlinx is still monitoring wave patterns,gathering financing and investors,and preparing an environmental impactstatement for the project. MECO willnegotiate a purchase power agreementwith Oceanlinx and seek approvals fromthe Hawaii Public Utilities Commission.Oceanlinx has also signed a Memorandumof Understanding with RenewableHawai’i, Inc., an unregulated subsidiaryof HECO, for possible passive investmentin the project.HECO’s President and CEO Mike Mayalso thanked members of the Mauilegislative delegation, includingRepresentative Angus McKelvey(District 10: Lahaina, Kaanapali, Kapalua,Maalaea, Kihei) who was instrumental inbring Oceanlinx and MECO together.And Mike May paid a special complimentto Representative Cynthia Thielen(District 50: Kailua, Kaneohe Bay), along-time proponent of ocean energy.“Representative Thielen’s persistence andcommitment to developing ocean energyin Hawai’i have helped bring us to thisday.”For Maui, it will be one more link in itsrenewable energy chain that alreadyincludes biomass and wind and willsoon include biofuels and wave energy.Indeed, Maui could become the firstHawaiian island to be 100 percentrenewable for electricity within a decade.To learn more about Oceanlinx go towww.oceanlinx.com.The project could be operational by2010. The cost, to be borne byOceanlinx and its investors, is estimatedat $20 to $30 million. A proposal in theState Legislature would provide Oceanlinxwith a Special Purpose RevenueBond, allowing the company to borrowat more attractive rates without puttingany burden on the public treasury.Graphics courtesy of Oceanlinx12
