Can I submit my rebate application before receiving the final permit?
No – a system installation must receive a final permit prior to applying for a rebate payment. Rebate payment applications (form B) that do not include a final permit will be rejected.
Can you explain the demand charges on my electric bill?
Demand charges apply to your highest amount of consumption, averaged within a 15 minute period, during the billing month.
Do all the wells and equipment remain down there because there is no sure way to plug the fractures left behind?
The only time that a fracture might be created is during step testing (required by the EPA to permit the well). The Step Rate Test (SRT) involves a series of constant rate injection tests, all with the same duration, with each successive step at a higher injection rate and injection pressure. The injection rate can be increased until the formation parting pressure is exceeded, at which point the injection pressure suddenly drops (showing up as in inflection point on the rate vs. pressure curve). However, the EPA does not always require that the parting pressure be reached, as long as the maximum injection rate and pressure attained in the SRT is greater than the desired operational injection rate (with a safety factor included). Having said this, any fracture produced in a SRT will be limited in size and should heal after injection ceases. The fracture shouldn't open again unless the formation parting pressure is exceeded again, which is not allowed under permit.

All "equipment" will be removed from both wells, and then the wells will be sealed underground and capped according to EPA direction and the Plugging and Abandonment Plans. This will be done in order to protect surface water and underground drinking water supplies.

Should I be concerned with overhead power lines?
In recent years concerns have been raised about the possible health effects of electric and magnetic fields (EMFs) from appliances, home wiring, and power lines. Numerous studies on this subject have been done throughout the world with results that are often hard to interpret and sometimes conflicting. While no one has proven that exposure to EMFs is harmful, many questions remain about how these fields, especially magnetic fields, might affect the human bodies.

By calling 79-POWER or e-mailing rosevilleelectric@roseville.ca.us, you may request a free copy of "Your Guide to Understanding EMF" or request an on-site EMF measurement.

While this may be the cheapest plan to operate now, how would it compare with future revenue loss or delays in home sales, and potential lawsuits for property damage, injuries, etc.?
The presentation to the RCONA group highlighted the selection criteria used to determine the LMS as the best option. Cost was one of the factors, but not the most important as the list below indicates. The selection criteria included the following:
  • The new process will improve our system reliability
  • The new process will be financially prudent
  • The new process must be environmentally safe and compliant
  • The new process must be a proven technology, acceptable to permitting agencies.

With proper engineering controls, direction from the EPA, and diligence in operating the process to the same high standard our customers already appreciate and enjoy with Roseville Electric, we do not expect to experience any of the adverse impacts mentioned in the question.
Who regulates Roseville Electric?
Roseville Electric is regulated by the Roseville City Council. The Roseville Public Utilities Commission meets the fourth Tuesday of every month and can be viewed on Comcast Channel 14 or SureWest Channel 73. The five-member commission serves as an advisory board to the City Council.
Why is Roseville Electric exploring changes to electric rates?
Roseville Electric is currently exploring rate changes to ensure our utility remains financially solvent and our customers continue to get competitively priced power and reliable electric service.
Why was my rebate application rejected?
Rebates will be rejected if the application is incomplete or incorrect. A rebate will be denied if the installed system does not match the specifications identified in the reservation issued. A rebate will be denied if it does not pass inspection by a 3rd Party HERS Rater.
Will Roseville Electric replace broken breaker switches, repair internal electric wiring or service electric appliances?
Roseville Electric does not replace parts or make repairs on customer-owned equipment or wiring.
Will the equipment corrode or deteriorate in the salt water environment, and what happens to the chemicals that have been dumped down there?
The equipment will be engineered to withstand the corrosive operating environment. Additionally, there will be routine inspections, safety devices and maintenance performed to ensure any issues that arise are resolved in a timely manner.

The injected water contains base constituents already found in the salt water aquifer we will be injecting into, but at a much lower percentage, and will remain in that salt water aquifer. This salt water is considered untreatable for drinking water by California and EPA standards, and as such the injected water will be diluted to such a degree within the salt water aquifer it would not be detected in a discrete sample.
Will there continue to be perpetual monitoring to ensure future environmental safety afterwards?
The EPA will require monitoring during the operation of the wells. They will also determine what type of monitoring will be required after well closure. The monitoring duration and frequency will be based on items such as:
  • Historical well operation data
  • Details of well construction such as depth and condition of well at the time of decommissioning
  • Any reported safety concerns or operational failures during the life of the well or at the time of decommissioning.
Your presentation at RCONA did not really address the other alternatives we asked more information about.
Due to the length of the answer, it will be posted on the FAQ page by Monday, July 6, 2013.
Are electric rates going to go up?
The Roseville City Council has the sole authority to set utility rates. Roseville Electric is recommending a 2 percent increase effective July 1, 2013 and 2 percent increase effective July 1, 2014. The consultant also recommends Roseville Electric increase its basic service charge to $14 in July 2013 and to $18 in 2014. 

We take any rate changes seriously. As a community-owned electric utility, we are charge customers based on our costs.
Why does Roseville have to dispose of water?
The cooling water is used to draw heat away from the equipment. The warmed cooling water then needs to be cooled and this is done through the process of evaporation. A side effect of evaporation is a high mineral content build up in the cooling water which can drastically reduce plant equipment efficiency. The management process removes the high mineral content water from the cooling water.
What information is the consultant or Roseville Electric considering when looking at rate changes?

There are significant factors that go into determining a rate structure. It is a very fluid and complex process that takes into account some of the following factors:

  • Buying and generating power
  • Buying renewable energy
  • Setting aside funds for the rehabilitation fund and rate stabilization fund
  • Providing funds for customer rebates and energy efficiency service
  • Compliance reporting
  • Fixing and upgrading the existing cables, poles, transformers, and substations
  • Developing plans to expand the existing system for new businesses and homes
  • Annual community reinvestment for street lights, traffic signals, police, parks and recreation, fire, and libraries.
Why are we considering this process?
The current process to dispose of the water used to cool the plant is very expensive to operate and maintain. At the time the plant was permitted, it was the best available option approved by the California Energy Commission. Now six years later, it’s appropriate to seek viable alternatives. If the proposed liquid management system is appropriate for the REP, it could save Roseville Electric up to $1.8 million in operation and maintenance costs annually.
How does it work?
Roseville Electric would inject water that has developed a high mineral content more than 1,500 feet below the underground drinking water aquifer. The 1,500 foot layer separates and will protect the drinking water from injection water.
How does Roseville Electric know how much electricity to buy or generate for the utilities 54,000 customers?
Roseville Electric energy analysts create multi-year Integrated Resource Plan to understand how much electricity the utility must buy or generate. The forecast also provides an analysis on what the energy will cost, both in the short and long term.
Does Roseville Electric buy power? Or does it generate its own power?
Roseville Electric does both. We buy power – including renewable energy – and also generate power.

We generate power at the Roseville Energy Park when it's more expensive to buy it. We buy power, when it’s cheaper to purchase, than to generate. That’s the way our power plant was designed to operate. It runs when it's cost effective.
Where is Roseville Electric’s liquid management system site?
The proposed site located on 5,000 square feet of City owned property adjacent to the Roseville Energy Park (REP). As part of the project the REP fencing will be extended to enclose the injection process equipment.
What is the process moving forward?

Roseville Electric's outreach process begins in February. Representatives of the utility are scheduled to attend service club and neighborhood meetings to explain the proposal. Additionally, Roseville Electric is hosting two public meetings:

  • 6:30 p.m., Tuesday, Feb. 19 at the Maidu Community Center, 1550 Maidu Drive
  • 2:30 p.m., Thursday, Feb. 21 at Riley Library, 1501 Pleasant Grove Boulevard

The Roseville Public Utilities Commission will review Roseville Electric’s rate proposal at 7 p.m., Tuesday, Feb. 26 in the City Council Chamber, 311 Vernon Street. The meeting is open to the public and will also be broadcast on Government Access Channels (Comcast 14/SureWest 73). The public can also watch the live broadcast online at http://www.roseville.ca.us/.

The City Council is tentatively scheduled to consider Roseville Electric's rate proposal in March 2013.

When will this start?
Roseville Electric staff expects to have a schedule outlining the remainder of this project in early 2012. Roseville Electric staff will also provide the City Council with an update on the completed liquid management system feasibility study along with staff’s recommendations for the next phase.
What will the liquid management system process accomplish?
The liquid management system process replaces the zero liquid discharge system in place at the Roseville Energy Park. Our analysis shows that a liquid management system is not as costly to operate or maintain when compared to the zero liquid discharge system.
What is the zero liquid discharge system?
The zero liquid discharge system, known as the ZLD, is the process of removing the high mineral content from cooling water used during the plant cooling process. The removed minerals form into a non-hazardous salt cake. The salt cake is then taken to the Placer County Materials Recovery Facility for disposal.

The process of removing and discharging cooling water from the plant must be approved by the California Energy Commission. During the plant permitting process, the ZLD was approved by the California Energy Commission because it was considered to be the best technology at that time.
Why do we want to use the liquid management system process?
Roseville Electric’s Energy Park’s ZLD is costly to operate and maintain. When Roseville Electric became aware that the California Energy Commission was permitting another plant using liquid management system technology, we initiated a study to determine if it would be cost effective to use at the REP.

In May 2010, a consultant study considered many alternatives and found the only option worthy of further consideration is a liquid management system. In 2011 a detailed feasibility study was completed.
What will the liquid management system cost?
While we do not have firm numbers, our consultant estimates the cost of a liquid management system at the Roseville Energy Park is $4.7 million. The study also estimates the annual operating and maintenance cost savings of the liquid management system project to be $1.8 million.
Is liquid management a proven technology?
There are currently more than 100 liquid management systems utilizing injection wells permitted in California. Of those, four were permitted for power plants.
What impact does a liquid management system have on the environment?

The liquid management process is considered to be an acceptable process to use in industrial process by the California Energy Commission and the U.S. Environmental Protection Agency.

Our study shows:

  1. The liquid management site’s separation from drinking water is more than required by federal standards.
  2. The injection zone exceeds the U.S. Environmental Protection Agency’s minimum criteria.
  3. The water from the power plant is cleaner than the water found (naturally) in the injection zone.
I live in on the west side of town; how will this affect my neighborhood?
The liquid management process will be designed to have no impact on its neighbors.
What would happen if we don’t do the liquid management system project?
We will continue to use the ZLD system. We are using that system now; By permit Roseville Electric cannot operate the Energy Park and not use the ZLD system.
Will my electricity rates increase because of the liquid management system project?
The use of a liquid management system at the Energy Park will not increase operation and maintenance costs.
What are our next steps?
Assuming the City Council approves this project; Roseville Electric will prepare and submit permit applications to the U.S. Environmental Protection Agency and California Energy Commission to use the liquid management process.
