RPU Board selects 100% renewable energy by 2030 scenarios

Tuesday, July 23rd, 2019

The Rochester Public Utilities (RPU) Utility Board selected two Resource Plan scenarios that include 100% renewable energy by 2030 at the July 23rd RPU Utility Board Meeting.

After a presentation of scenario options and costs of varying renewable energy levels and resources, the RPU Utility Board voted unanimously to direct staff to further pursue two 100% renewable scenarios, one including a peaking generator and one involving battery storage.

This historic vote comes after significant engagement with Rochester citizens, along with many hours of work and research by RPU staff.

“RPU prides itself on its commitment to work with the Rochester community and to be good stewards of resources. Today’s decision to go to 100% renewable energy by 2030 is a testament to the commitment by  RPU Board, RPU staff, and Rochester citizens working together to find the best outcome for all,” said RPU General Manager Mark Kotschevar.

Rochester joins the cities of St. Paul, Minneapolis, and St. Louis Park as Minnesota cities committed to 100% renewable energy.

The Resource Plan scenarios selected call for RPU to meet all of its energy needs through 100% renewable energy sources and remaining capacity requirements with either a new 220 megawatt natural gas powered facility or battery storage.

The Resource Plan presentation is available on the RPU website at www.rpu.org. For additional questions, contact Tony Benson at 507.280.1534.

New Report Shows that Solar, Wind, and Storage Can Competitively Power a Majority of Minnesota’s Electric Needs

Friday, November 16th, 2018

New Report Shows that Solar, Wind, and Storage Can Competitively Power a Majority of Minnesota’s Electric Needs
 

Minnesota can produce 10 percent of its electricity from solar by 2025 and 70 percent from solar and wind by 2050 at generation costs comparable to natural gas.

Building additional solar and wind capacity coupled with energy curtailment is less expensive than building long-term or seasonal storage.

 

Thursday, November 15, 2018, Saint Paul, MN: Minnesota has been ambitious in meeting its renewable energy goals: the state hit its 25 percent renewable energy by 2025 goal early this year using wind, solar, biomass, and hydro power.

A report released today finds that Minnesota could achieve 10 percent solar by 2025 at costs comparable to natural gas generation. Further, the report finds that expected cost decreases in solar, wind, and storage will enable Minnesota to achieve 70 percent solar and wind by 2050 at costs comparable to natural gas generation.

The Solar Potential Analysis Report, prepared by Clean Power Research for the MN Solar Pathways Initiative, includes several scenarios that model future renewable energy generation costs.

“This report shows that a renewable energy future is not only possible in Minnesota, but that the generation cost of solar, wind, and storage is competitive with natural gas generation,” said Brian Ross with the Great Plains Institute. “We also learned that coupling additional solar and wind capacity with energy curtailment when production is not needed eliminates the need for costly seasonal energy storage,” added Josh Quinnell with Center for Energy and Environment.

Key findings from the report:

  1. Solar and wind can serve 70 percent of Minnesota’s electrical load in 2050. Solar and wind can serve 70 percent of Minnesota’s load at generation costs that are comparable to the levelized generation cost of new natural gas generation.
  2. Additional capacity coupled with energy curtailment is considerably less expensive than, and a viable alternative to, long-term or seasonal storage in a high renewables future. Declining costs of solar and wind generation (<$20/MWh) will enable solar and wind to be economically curtailed during periods of high production and low load.
  3. Using other flexible generation resources in limited amounts support a high renewables future. The strategic use of other generation resources during brief periods of low-solar and low-wind production will significantly reduce the storage, solar, and wind capacities needed to serve Minnesota’s hourly load, reducing the generation cost for 70 percent solar and wind by nearly half.
  4. Storage is an important part of a high renewables future; it expands the dispatch capabilities of wind and solar assets. Sufficient quantities of storage smooth out the intra-hour variability of solar and wind.
  5. Shifting of key flexible loads may further decrease generation costs. Load shifting of new electric vehicle and residential domestic hot water loads demonstrated a potential 10-20 percent decrease in generation costs by moving the consumption to different times in an hour, day, or week.

 

“The MN Solar Pathways Solar Potential Analysis Report demonstrates that it’s possible to find an economical pathway to higher renewable generation,” said Jeff Ressler, CEO of Clean Power Research. “Critical to this project was the use of time-correlated solar, wind and load generation datasets in advanced software tools to more precisely see the effects of different scenarios, such as varying amounts of solar, wind and storage capacities.”

Mark Ahlstrom with Energy Systems Integration Group and a Technical Committee member who contributed to the development of the report said, “The MN Solar Pathways Solar Potential Analysis approach is conservative but relevant, and there is a growing body of good work that shows that penetrations in the 70-80 percent renewable range are quite feasible and not unduly expensive. Best of all, we have the key technologies today to get to 70 percent renewable energy and to accommodate massive electrification of other energy sectors.”

Rochester Public Utilities announces Community Solar Program and Kickoff Informational Meetings

Wednesday, June 7th, 2017

Rochester Public Utilities (RPU) announces a new community solar program named SOLARCHOICE.

The SOLARCHOICE community solar program is an alternative to rooftop solar. It allows residential customers the opportunity to join in the solar movement without having to install solar on their property. It opens up solar participation to customers who:

  • Want to participate in solar but are unable to do so due to current restrictions.
  • Share a passion for solar energy resources and believe community solar is right for them.

According to the National Renewable Energy Laboratory (NREL), nationwide, only 25% of residential rooftops are suitable for solar, so rooftop solar is not an option for these customers. Community solar generally requires a lower upfront cost, eliminates the installation hassle, and removes the burden and risk of ongoing maintenance. Larger, utility-scale solar gardens capture economies of scale that are then passed on to program participants.

Instead of putting panels on their own roof, customers subscribe to a large solar project called a community solar garden with thousands of panels. Customers purchase subscriptions, along with many other residents who share their commitment to renewable energy, for the energy produced by one or more panels in the community solar garden. Each month the customer receives an energy (kWh) credit for the solar electricity generated by the subscribed panel(s) for the term of the subscriptions. RPU will offer a 12-year subscription plan for $650 per panel. Each panel is expected to average 501 kWh per year.

“After gathering research and listening to our customers about their desire for renewable energy options, we are proud to offer SOLARCHOICE”, said RPU General Manager Mark Kotschevar.

The SOLARCHOICE community solar garden is planned to be built in Princeton, MN on a site near the municipal airport once 25% of the planned community solar garden is under subscription by customers of RPU and other SMMPA Member utilities.

Customers who want to learn more about SOLARCHOICE community solar can attend one of the informational meetings scheduled for June 15 from 6-7pm or June 20 from 1-2pm at the RPU Service Center (4000 East River Road NE). Additional information can also be found at www.rpu.org.
