Marinas to Become More Energy Efficient with Echelon's Technology; Pleasure Ports and Marinas Latest in Trend to Utilize Control Networks for Energy Savings Solutions

Echelon Corporation (Nasdaq:ELON), the leadingtechnology supplier for the widely-used LonWorks(R) control networkingstandard, today announced that its technology is to be used toremotely control and monitor pleasure ports and marinas in theMediterranean to reduce energy and maintenance costs and increasesecurity and safety by managing access control. The PASS'PORT solutionfrom Indigo Instruments, the first integrated energy management,reservation booking and control application of its kind, is designedto reduce operating costs by up to 25% in ports and marinas. PASS'PORTis being introduced this week at the Salon Nautique International deParis event in France.

"Marina and port operators are looking for a way to increase theirlevel of service in order to make their harbors more attractive toboat owners across the Mediterranean's large network of pleasureports. Our unique solution offers dramatically improved energyefficiency and energy theft prevention to marina operators, enhancedsecurity to marina patrons, and increases convenience and customerloyalty while generating new business opportunities for harbors tosell added-value services such as remotely controlled alarms onboats," said Emmanuel Baret, INDIGO Instruments' CEO. "We choseEchelon's technology and DotVision's Enterprise Monitoring Softwarefor our solution because this combination is a reliable, proven way ofremotely monitoring and commanding devices, combining the bestperformance and price available."

Typical factors increasing operational costs for marinas includeelectricity theft when boat owners plug into electrical outletswithout authorization, accounting for up to 10% of all energy costs.The physical check-in procedure required upon arrival to turn on andoff electricity and water supplies increases operational expenses byapproximately 15% annually. Other cost-escalating items includeoverseeing security access and lighting control for the port, whichcurrently allow no customization to the standard on/off schemes orschedules.

INDIGO Instruments' PASS'PORT solution uses Echelon's technologyto remotely monitor and control various subsystems in pleasure portsand marinas. Installed on each pier are multiple electric and waterdistribution cabinets which can accommodate up to four boats each.Each cabinet houses devices based on Echelon's power line signalingtechnology, such as switches, valve controllers, and energy meters,all accessed via Echelon's i.LON(R) 100 e3 Internet Server. Otherdevices on the power line based network include door controllers,access cards, and lighting controllers for outdoor lighting, air andwater temperature sensors, and wind speed sensors. Software fromDotVision, a leading provider of human machine interface (HMI)software and enterprise monitoring applications, provides integratedWeb access to analyze energy consumption, identify outages, displaysecurity video camera feeds as well as reserve a slip for a specificboat. The installation utilizes existing electricity wiring todramatically reduce the costs of implementing the system and achievethe reliability requirements of the target market.

The solution allows harbor masters to remotely connect anddisconnect electricity in individual boat slips, measure how muchelectricity was used by each occupant for billing purposes, and manageother systems such as security access control and lighting systems forthe entire port. Harbor masters can become more efficient inday-to-day operations, saving time by remotely identifying andresolving failures or alarms, and by forecasting maintenance repairsand downtime. Moreover, energy costs can be effectively measured andallocated to a specific boat, simplifying the billing process.

The system will be adapted for use in camping grounds to allowself-service check-in for campers and recreational vehicle campers,allowing the distribution of electricity, water, access control,wireless internet, and swimming pool automation. The increasedconvenience will enable after-hour check-ins without employing extrastaff, creating a substantial savings for camp ground owners andoperators.

"We are pleased to be a part of this unique solution thatexemplifies the value of an open control networking approach to energyand remote monitoring and control solutions," said Bea Yormark,Echelon's president and COO. "There are real, measurable benefits tobe gained by utilizing control networks to modernize common tasks andprocesses. This can help any business become more efficient,maximizing budgets and staff allocation, and help to reduce energy andmaintenance costs."
