Union City: Sanitary group set to save money, energy with $14.5 million facility

UNION CITY — The Tri-City group that treats wastewater and sewage says it will save energy and income from a new trickery that reuses gas to power partial of a Union City plant.

The Union Sanitary District’s “cogeneration facility” translates a biogas that it generates into electrical power during a Benson Road property, that could revoke a agency’s power bills by tens of millions of dollars over a new building’s life span.

“Everybody wants to save on energy costs while regulating materials that would differently be wasted, and this will assistance us grasp that” pronounced district house President Manny Fernandez. “It’s a good idea, formulating energy out of something you’d routinely dispose of.”

The Union Sanitary District treats millions of gallons of wastewater and offers collection and ordering services to residents and businesses in Fremont, Newark and Union City. Its sum annual check this year is around $56.7 million, district General Manager Paul Eldredge said.

The $14.5 million cogeneration trickery took dual years to build during a district’s 33-acre plant on a western corner of town. Last month, a group distinguished a opening of a 30-foot-tall, 5,000-square-foot steel building. The cogeneration trickery was partly saved by a scarcely $3.4 million extend from PGE, Eldredge said.

The special district for decades has used methane gas combined from treating and violation down sewage and wastewater. That gas afterwards has been reused as energy to power a agency’s cogeneration engines.

The aged engines, in use for about 30 years, were transposed recently by bigger ones that are some-more fit and can repurpose a larger turn of methane gas, district leaders said. The new engines, approaching to final about 20 years, are means to use all of a gas constructed by a plant’s diagnosis system, since a aged ones could usually modify about 50 percent of it, Eldredge said.

“Wastewater diagnosis is an energy-intensive process, and we’re always looking for ways to revoke a operational expenses,” he said, “The volume of power that we beget (with a new engines) will isolate us and ratepayers from rising power costs.”

The upgraded apparatus has warranted a approval of Rep. Eric Swalwell, D-Dublin, who final month gave Union Sanitary District a special congressional certificate. He lauded a group for a “commitment and loyalty to renewable energy.”

If a trickery works as it should, group leaders said, a district competence revoke a annual $2 million energy costs by some-more than 75 percent, holding a yearly check reduce than $500,000.

“This is one of many USD projects that assistance us … make a best use of a public’s assets,” Eldredge said.

Intel catches a wind with rooftop micro-turbine array

SANTA CLARA — Intel is branch a roof of a Santa Clara domicile into a mini-wind plantation with what it says is one of a largest micro-turbine arrays in a country.

The V-shaped arrangement of 58 wind-powered turbines, being commissioned this week, is approaching to beget about 65 kilowatt-hours of power that will be used to yield electricity to a discussion core in a wayward Robert Noyce Building on Mission Boulevard.

The chipmaker called a micro-turbines a “proof of concept” project.

“We are perplexing to know how this form of record integrates into Intel and where are a best locations for it around a world,” pronounced Marty Sedler, executive of Intel’s tellurian utilities and infrastructure.

JLM Energy organisation members implement their Zefr micro wind turbines on a rooftop of Intel Corporations Headquarters in Santa Clara, Calif., on

“We’ll share a information and share a information so other people can request it to their possess businesses and homes,” he said.

The micro-turbines are 6 to 7 feet tall, import about 30 pounds any and are positioned during a roof’s corner where they can accumulate a many wind, that averages about 8 to 9 miles per hour in a area. They share a roof with an array of solar panels.

“This is only another stump adding to a sustainability program,” Sedler pronounced

Intel’s new wind turbines arrive during a time when vital tech companies are branch to immature power. Apple and Google announced immature projects in February. Apple is building a solar plantation in Monterey County and Google is building a timberland of wind turbines on Altamont Pass nearby Livermore.

Intel says it has been immature for years, and was recently famous by a U.S. Environmental Protection Agency, for a seventh year in a row, as a largest intentional client of immature power in a country. It has solar installations on 12 Intel campuses in a U.S., Israel and Vietnam that beget some-more than 12 million kilowatt-hours of power per year of purify energy, as good as a solar prohibited H2O complement that reserve scarcely all a needs of Intel’s dual campuses in India.

The new array “is one of a largest we’ve identified anywhere,” Sedler said. “One of a things Intel does that’s a small opposite from other companies is that all a projects we have finished to date have been on a campuses. It’s not a answer, it’s one of a answers. The pivotal is to get off a grid.”
