Weather Station Data for Energy Forecasting in Huntington Beach

Harnessing Weather Data for Energy Forecasting

AES is a global energy company that has purchased CWS weather stations for several US project locations since 2012.

Ellie Thacker, CWS Technical Sales Engineer, recently got a site tour and sends the following report:

The Huntington Beach Energy Project (HBEP), located in Huntington Beach, California, began operation in 2020. The HBEP is an 844-megawatt power generation plant that uses a natural gas-fired, combined-cycle turbine and a simple-cycle turbine.

The HBEP is one of the cleanest power generation plants in California due to its emissions control equipment.

The Challenge

Gas-fired turbines run more efficiently when the ambient temperature is lower. When the ambient air is colder, it is denser, which means more air can fit in the given volume that passes through the machinery. Relative humidity also affects the efficiency of the turbines.

John Islas, Instrumentation Controls and Electrical Technician, showed how they use the weather data from their two Columbia Weather Systems stations.

Temperature and relative humidity measurements are used to determine the amount of power that the plant can produce on a given day, which is then reported to the state of California.

If the power plant under-produces, they must make up the difference monetarily. Having accurate assessments of the plant’s ability to produce power in given environmental conditions prevents unnecessary costs, which is why having on-site weather monitoring is critical to their operation.

Weather Monitoring Solution

Since its start, the Huntington Beach Energy Project has been using the Magellan MX500™ weather station. This model includes wind speed and direction, air pressure, temperature, and humidity. In more recent years they have added an additional temperature and humidity sensor module at the plant.

For seamless integration into their controls system, they use the 4-20mA interface option for both systems. Weather data is displayed front and center in their control room for real-time monitoring.

Islas reported that they have “never had any problem” with the weather stations.

Thank you for the tour!

CWS Attends HazMat Conference

Image
Last week the  Oregon State Fire Marshal ’s office held their Regional HazMat Emergency Response Team Conference. Nader and Martha were honored to attend.  Beginning in 2005, the OSFM has outfitted HazMat teams with portable and vehicle-mount weather stations from CWS.  The conference was held in Sunriver, Oregon Over the past few years, the teams have been upgraded to the latest Magellan MX weather stations with their new apparatus through Hughes Fire Equipment . In addition to immediate situational awareness, met data from the weather stations is integrated with PEAC software for plume modeling and incident reporting.  Having fun at the "HazMat Olympics" CWS President Nader Khoury with Aristatek rep Renée Soriano   BNSF Railway's HazMat trailer Aristatek rep Renée Soriano presented the PEAC software integration.   Justin Piper, of BNSF (CWS customer) presented on Rail Hazardous Material Response. A key point was Start Gathering Information: What are your wind and wea

School Invests in Weather Station for Hands-On Learning

Image
We are always excited when educators invest in giving their students hands-on knowledge of how weather works, how it’s measured, and how it affects them. South River High School in New Jersey does just that. Last year, the school installed a  Capricorn FLX Weather Station  on one of their buildings. The Climate Change Club uses the data to report hourly weather readings to the National Weather Service. According to their website: “This will make South River High School a weather hub for pilots to collect current weather conditions of our area. The information that the club collects will also be archived for climate change data.” Administrator Kamila Miazio added that the club “provides a weekly forecast, satellite imagery of CONUS, and severe weather updates. The advisor is working to teach students METAR code (the weather code that pilots use to see current weather conditions for the area), report an hourly automatic observation with the weather equipment, record the data and report i

New Heated Magellan MX™ Weather Station Models

Image
Does wintry weather affect the accuracy of your met instruments? Heated sensors can help prevent frozen precipitation from accumulating on weather equipment and causing faulty data. Heated all-in-one sensors are available for the Orion ™ and Pulsar ™ weather stations. Heated wind sensors and tipping bucket rain gauge are available for Capricorn FLX ™ Weather Stations. And now a heated option is also available for the Magellan MX ™ 600, 501, and 500 weather station models. The heating function allows these models to operate easily during snow and ice accumulation with a low power demand (nominally 9W). These Magellan MX models incorporate GPS readings, wind speed and direction, pressure, temperature, relative humidity, and compass. The MX501 adds solar radiation. Magellan MX600 adds rainfall.
