Potential seen in floating solar for wine, ag

Gary Quackenbush, NORTH BAY BUSINESS JOURNAL
Sonoma County clean energy and water officials have set up talks with vineyard, farm, dairy and other landowners in Sonoma Valley and around Healdsburg about using their irrigation ponds for what is said to be the largest floating solar-electricity project in the U.S. and the second-largest in the world.
Sonoma Clean Power and Sonoma County Water Agency plan to hold additional information sessions throughout the county over the next three months to assess landowner interest in adopting a solar-over-water option. This comes after Sonoma Clean Power signed an agreement with San Francisco-based Pristine Sun in late February to install a 12.5-megawatt solar farm on pontoon docks at six holding ponds operated by the water agency in northwest Santa Rosa and Sonoma Valley. The power agency had reviewed bids from four solar providers.
The sunset of rooftop solar is not over the horizon, but the dawn of a new application for photovoltaic panels installed as floating arrays is an emerging trend in the industry. Some have already been placed above vineyard irrigation and frost prevention ponds as well as on fully treated wastewater reservoirs. The largest floating solar array in the world is a 13.4-megawatt installation by Kyocera TCL Solar on Yamakura Dam reservoir near Tokyo.

Sonoma Clean Power inks deal for floating solar panel project

Matt Brown, THE PRESS DEMOCRAT
Sonoma County’s new public electricity supplier is turning to the sun and water — the airspace over treated sewage ponds, specifically — to generate power for local homes and businesses.
Under a deal signed Thursday with a San Francisco-based renewable energy developer, officials with Sonoma Clean Power, now the default electricity provider in Sonoma County, unveiled a plan to install a 12.5-megawatt solar farm on floating docks atop holding ponds operated by the county Water Agency.
When completed in 2016, the project, which will provide enough electricity to power 3,000 homes, will be the largest solar installation in the county.
It also will help fulfill one of Sonoma Clean Power’s central goals — to develop local sources of renewable energy for its expanding customer base, now taking in more than 160,000 residential and commercial accounts across five cities in the county.
Before its launch last May, and through its first nine months of operation, the public venture faced pointed questions as to how quickly it would be able to spearhead local energy projects given constraints on rural land use and the comparatively higher price of power from smaller systems versus large, far-flung industrial sources.
Sonoma Clean Power officials said the planned solar installation served as a key early benchmark of progress in the agency’s rollout.

Sonoma Clean Power news and public meetings

Teri Shore, SONOMA COUNTY GAZETTE
People in Sonoma and across the county are now choosing whether to buy electricity from Sonoma Clean Power or opt out and stay with Pacific Gas & Electric. In any case, PG & E will continue to send electric bills for both electricity providers, provide natural gas, operate power lines, and respond to power outages. The opt-out approach is mandated by state law in order to provide start-up community-based energy providers a chance to compete with established investor-owned utilities.
Sonoma Clean Power plans to spend about $18 million on energy this year to serve customers across Sonoma County now that all cities have joined, except Healdsburg which has its own power company.
Public workshops will be held in Petaluma, Rohnert Park and Cloverdale in both English and Spanish in February through April to inform people and answer questions about Sonoma Clean Power. See full schedule here: sonomacleanpower.org/meetings/
At the January 8 board meeting, First District (Sonoma Valley) Supervisor Susan Gorin turned over the chair’s gavel to Cotati City Councilman Mark Landman. She served as the board chair for the past two years while Sonoma Clean Power started up as the county’s default electric power provider. Gorin will remain on the board.
At the meeting, Gorin said she was pleased with the success of Sonoma Clean Power so far. She also called for as much public oversight as possible without impairing the agency’s ability to negotiate good deals for renewable and standard electric power.
To fill vacated and expiring seats on two community advisory committees, Gorin requested that staff alert the public and all the cities that applications are being solicited for the Ratepayer Advisory Committee and the Business and Operations Committee. Interested people should contact Sonoma Clean Power at sonomacleanpower.org.
Sonoma Mayor David Cook has an important new role overseeing the purchase of electric power by Sonoma Clean Power for customers in Sonoma and across the county. Cook represents the City of Sonoma on the Sonoma Clean Power board of directors, taking over the director seat previously held by former Councilman Steve Barbose.
The mayor was chosen by the power agency’s board of directors at the January 8 board meeting to chair a new three-member panel charged with reviewing and approving electric power deals worth over $250,000. The two-year-old non-profit power agency buys electricity generated by geothermal, natural gas, and other renewable and conventional sources.
The power procurement panel members will provide public oversight of power deals that are negotiated by Sonoma Clean Power Chief Executive Officer Geoff Syphers and his staff. David King of Petaluma and Patrick Slayter of Sebastopol were also appointed to the ad hoc power procurement panel.
Gorin also asked for development of a policy that requires public sharing of third-party (ex-parte) communications held with board members and staff.
Sonoma Clean Power is also preparing to roll out new community based green power pilot programs this summer. Recently, about 50 people turned out for a workshop where SCP proposed three possibilities including installing solar panels on the rooftops or properties of non-profit organizations, installing new electric vehicle plug-ins or conservation incentive programs for homes and businesses. Ideas on those or other projects can be submitted until January 15. For more information, contact Sonoma Clean Power at sonomacleanpower.org
Sonoma Clean Power versus PG& E
Sonoma Clean Power’s mission is to provide locally based renewable energy at rates competitive to PG&E’s. It was established under state hard-fought state legislation that allows for establishment of “Community Choice Aggregation” electric energy providers.
Instead of operating like a corporation charged with prioritizing profits and return to shareholders, Sonoma Clean Power is set up to operate as a non-profit government agency that re-invests profits in renewable energy projects and programs that benefit the community. Those programs are just beginning with a solar power project in Cloverdale that will generate enough electricity for 300 homes. Sonoma Clean Power does not generate power or build projects, but contracts to buy power.
Right now, Sonoma Clean Power’s basic residential rates are about 3 to 4 percent lower than PG&E’s overall. However, some PG&E plans may be better for low income customers that pay the same power costs every month based on average annual use. Homeowners with solar panels may also come out ahead by staying with PG&E in the short term until the true-up period for the past year. The rate difference between the two providers are likely to change over time.
See a full rate comparison here: www.pge.com/includes/docs/pdfs/myhome/customerservice/energychoice/communitychoiceaggregation/scp_rateclasscomparison.pdf
When it comes to renewables, Sonoma Clean Power offers a basic energy program called “CleanStart” and a more expensive all-renewable choice called “Evergreen” that is more expensive.
Right now, CleanStart is comprised of 33 percent renewable generation sources versus PG&E’s 22 percent (See sonomacleanpower.org/wp-content/uploads/2013/12/SCP-2013-Electric-Power-Generation-Mix.pdf). Geothermal power from Sonoma County’s geysers is the source of most of Sonoma Clean Power’s renewables with some wind and biomass. Natural gas is a big part of the mix. No solar is online yet, but the agency has contracted to buy from new projects coming on line in Sonoma County and the Central Valley.
PG&E generates and buys a mix of geothermal, wind, biomass, solar, nuclear and hydroelectric – though nuclear and most hydroelectric is not considered renewable in the state of California. PG&E operates Diablo Canyon nuclear plant, which provides 22 percent of its power and is not considered renewable.
As with all California energy providers, PG&E is required to increase renewables to 33% of total procurement by 2020. Governor Jerry Brown recently called for 50% renewables by 2030.
The mysteries of electricity and the grid
All the electricity that powers your home or business is the same. Electricity in itself is clean. There is no difference in the electrons that are transmitting through power lines to your home.
The key to whether electricity is clean or green or not is based on how it is generated and from where. Renewable energy such as geothermal, wind, solar generally produces far less negative impact on the environment and produces less air pollution and greenhouse gases than fossil fuels such as natural gas or coal.
So when you invest in a renewable energy plan, that cleaner energy is not delivered to your location, but rather is supplied to the electric grid. The more renewable energy that reaches the grid, the more dirty energy is displaced.
Ultimately, if enough renewable energy is produced to meet the demand for power, then dirty fuels will eventually be phased out if no longer needed.
Switching to cleaner fuels will require major changes to the way that electricity is delivered and stored. One of the biggest challenges we face in California is how to store ample solar and wind energy generated during the day to use in the evening when everyone is at home eating dinner, watching TV, playing games on the computer and listening to music.
Right now we rely on mostly fossil fuels such as natural gas, hydro and nuclear power that is up and running all the time or can be taken on and off line as needed.

Sonoma Clean Power plugs in big geothermal, solar deals

James Dunn, NORTH BAY BUSINESS JOURNAL

Startup power utility Sonoma Clean Power on Wednesday reported two long-term contracts for geothermal and solar power.

The first contract is for 10 years of geothermal power from Calpine’s Geysers facilities in northeastern Sonoma County. The deal provides steadily rising volumes reaching 50 megawatts in 2018. By then the total energy coming from that source will amount to 23 percent of Sonoma Clean Power’s mix.

The second contract is for 20 years of solar power from Recurrent Energy, adding 40 megawatts to the agency’s previous purchase of 30 megawatts for a total of 70 megawatts.
The alternative-power agency claims rates about 4 percent lower than PG&E’s rates. The new geothermal and solar deals will help the agency keep its rates low into the future. Sonoma Clean Power provides electric generation service to customers in much of Sonoma County, with about 22,000 residential customers.

In December, an additional 140,000 customer accounts will be eligible to receive the agency’s cleaner mix of power. All cities in Sonoma County participate in the program except Petaluma and Rohnert Park, where a vote on whether to allow participation in the agency will be taken by Jan. 31. Healdsburg has its own municipal utility and is not a part of Sonoma Clean Power.

Update on anti-community choice proposed law, AB 2145

Climate Protection Campaign

The anti-community choice bill, AB 2145, is now before the full Senate for a vote. Our work facilitating a statewide coalition removed the worst of the bill. Two problematic elements remain: a three-county restriction and inclusion of a CPUC complaint process. Calls to senators urging a “no” vote are still encouraged.

No on 2145

Clean-power agencies relieved at legislation change

Jeff Quackenbush, NORTH BAY BUSINESS JOURNAL

A key element of legislation that advocates of Sonoma Clean Power and similar alternative-energy agencies insist would threaten their ability to form and operate could be switched off, thanks to state Senate action Monday.

The requirement for electricity customers to opt-in to a community-choice aggregation (CCA) agency was dropped from Assembly Bill 2145 during a meeting of the state Senate Energy, Utilities and Communications Committee.

“We protected Sonoma County’s right to participate in Sonoma Clean Power,” Geof Syphers, agency CEO, said about that vote. The county’s CCA started service May 1 and serves all areas but Healdsburg, which has its own utility, and opt-outers Petaluma, Rohnert Park and Cloverdale.

Utilities attacking choice — again

Mark Landman and Natasha Granoff, Op-Ed, THE PRESS DEMOCRAT

In 2002, the California Legislature passed a law enabling cities and counties to establish Community Choice Aggregation programs such as Sonoma Clean Power and Marin Clean Energy. PG&E spent millions of dollars trying to defeat Community Choice by way of Proposition 16 in 2010. But the voters said a resounding no.

Customers of these new programs are starting to reap benefits that go beyond the vision legislators had in 2002. At least 12 more California communities are in varying stages of starting up community choice energy programs.

But community choice systems will be crushed if Assembly Bill 2145 passes. This proposed law, sponsored by PG&E and other privately owned utilities, is now speeding through the state Legislature.

A lot is at stake. If AB 2145 becomes law, Californians will lose the opportunity for choice of electricity provider, competition, lower electricity rates, greener power, local economic development, local decision-making and leadership in a clean energy future.

As an example of a benefit that is at risk, a recent rate analysis conducted for Sonoma Wine Company shows that rates for greener electricity through Sonoma Clean Power will be 10 to 11 percent lower than PG&E’s. All Sonoma Clean Power customers are currently receiving at least a 4 percent savings on their electric bill. If AB 2145 were law, Sonoma Clean Power’s cleaner power and cheaper rates would not be possible because the program would not exist.

So why would any legislator vote for AB 2145? Because California’s big investor-owned utilities want to fend off the serious competition posed by community choice and have tapped powerful allies to push AB 2145 through.

Sonoma Clean Power inks deal for 30 MW solar project

Press Release, Sonoma Clean Power, SONOMA COUNTY GAZETTE

Sonoma Clean Power (SCP), Sonoma County’s new electricity supplier, signed an agreement today with leading North American solar project developer Recurrent Energy, to construct 30 megawatts (MW) of solar power in California, and to supply the energy to SCP customers.

“This 20-year deal secures pricing that helps Sonoma Clean Power maintain its low costs and deliver further reductions in greenhouse gas emissions,” offered Supervisor Susan Gorin, Chair of the SCP Board of Directors.

Power from the new solar facility, located in the Central Valley, will be sufficient to supply 9,000 homes starting in late 2016 when construction is completed. The project will be constructed under a project labor agreement. 

“The cost of this power is lower than any of our current contracts for renewable energy – helping to make room in the budget to support investments into local Sonoma County projects,” said Sonoma Clean Power’s CEO, Geof Syphers. “Early work on local power includes an existing deal for a similar amount of power from Calpine’s Geysers geothermal facility, a proposed feed-in tariff program for larger customers wanting to sell power, and improvements to the existing net metering program for solar customers,” Syphers added.

Sonoma Clean Power flips switch for first customers

Eric Gneckow, NORTH BAY BUSINESS JOURNAL

After three years of planning, Sonoma County’s new renewable energy-focused electricity provider, Sonoma Clean Power, on Thursday officially began serving its first group of more than 20,000 customers.

It marks the second launch of service in California for a community choice aggregation–type power agency, a model that purchases power on behalf of its customers and delivers it over the power grid largely maintained by Pacific Gas & Electric Co. The start of Marin Clean Energy in Marin County in May 2010 was the first.

Officials in the Sonoma County effort celebrated a higher-than-expected rate of enrollment during a regularly scheduled meeting of the governing Sonoma Clean Power Authority on May 1.

“Today’s the day,” said Susan Gorin, chair of the agency’s board of directors and a Sonoma County supervisor. “It’s going to be a day of celebration.”

Some customers opting out of Sonoma Clean Power

Derek Moore, THE PRESS DEMOCRAT

About 5 percent of eligible business and residential customers so far have opted out of Sonoma County’s start-up public power agency, some over concerns the service won’t be as reliable as PG&E.

Sonoma Clean Power projects about 20 percent of eligible customers ultimately will opt out of the service, which launches May 1. About 24,000 potential customers — most of them businesses — are part of the first wave of service.

Geof Syphers, CEO of the power startup, said a “handful” of potential customers who received letters detailing the program cited reliability concerns as their reason for declining the service.

Under Sonoma Clean Power, PG&E would continue to provide services such as billing, metering and grid maintenance. Syphers said the “reality” is that “all aspects of reliability will be handled by PG&E in exactly the same way they are handling them now.”
