One example of a collocated fossil fuel-fired EGU and renewable energy installation is demonstrated by Sempra Energy’s neighboring natu ral gas and solar PV projects located at 701 Eldorado Valley Drive in Boulder City, Nevada. A ccording to satellite imagery, the Desert Star Energy Center 480 megawatt natural gas plant is located alongside the Copper Mountain Solar 1 and 2 plants of 58 megawatts a nd 92 megawatts, respectively.
In late 2014, the Kentucky Public Service Commi ssion approved Louisville Gas and an Electric (LG&E) and Kentucky Utilities (KU) request to construct what w ill be the state's largest solar photovoltaic facility at th e utilities' E.W. Brown Generating Station with has 3 coal units (113, 180 and 464 megawatt nameplate capacity) and seve ral simple cycle natural gas units. The 10- megawatt solar facility is exp ected to go online in 2016 and will provide renewable electricity directly to the grid, represented by the follo ing December 22, 2014 press release from LG&E and KU.
The press release, which can be found here https://lgeku.com/newsroom/articles/2014/12/22/kpsc-approves- lge-and-kus-request- build-states-largestsolar-facility as of August 2015, is titled, “KPSC Appr oves LG&E and KU's Request to Build State's Largest Solar Facility.” Here is the content of the press release.
This project and its approval is the result of positive, productive agreements between the utilities, the Sierra Club and industria l partners for the benefit of Kentucky.
The Kentucky Public Service Commission ap proved LG&E and KU's request to construct what will be the state's largest so lar photovoltaic facility in Mercer County at the utilities' E.W. Brow n Generating Station.
“This is a good example of how LG&E a nd KU, the Sierra Club and our industrial partners worked together for a mutually be neficial solution for Kentucky," said LG&E and KU Chief Operating Of ficer Paul Thompson.
“While Kentucky is not blessed with an abundance of wind and solar energy, the approval gives us the opportunity to learn more about solar technology,” said Thompson. “By utilizing our existing prope rty and taking advantage of tax incentives, we can offer our customers another source of generati on, similar to our existing hydro plants.”
The 10-megawatt solar facility is expected to go online in 2016 and cost $36 million.
The solar array will consist of solar panels and associated transformers, switches and other equipment. The number of solar panels will be driven by the final design of the solar array selected from the competitive bidding process.KU will own 61 percent of the array and LG&E the remaining 39 percent — a split based upon the relative load of the two utilities during daylight hours.
LG&E and KU will continue maintaining a diverse generation portfolio and are continually evaluating potent ial energy supplies to determ ine which available sources would allow the company to sufficiently prov ide safe, reliable, least-cost energy using commercially available technologies.

## KPSC Approves LG&E and KU's Request to Build State's Largest Solar Facility

Posted | Dec 22, 2014

Description: This project and its approval is the result of positive, pr oductive agreements between the utilit ies, the Sierra Club and indu strial partners for the benefit of Kentucky.

The Kentucky Public Service Commission approved LG&E and KU's re quest to construct what will be the state's largest solar photo voltaic facility in Mercer County at the utilities' E.W. Brown Generating Station.

“This is a good example of how LG&E and KU, the Sierra Club and ou r industrial partners worked together for a mutually benefici al solution for Kentucky," said LG&E and KU Chief Operating Officer Paul Thompson.

“While Kentucky is not blessed with an abundance of wind and sola r energy, the approval gives us the opportunity to learn more about solar technology,” said Thompson. “By utilizing our existing property an d taking advantage of tax inc entives, we can offer our custom ers another source of generation, similar to our existing hydro plants.”
The 10-megawatt solar facility is expected to go online in 2016 and cost $36 million.

The solar array will consist of solar panels and associated transf ormers, switches and other equip ment. The number of solar pan els will be driven by the final design of the solar array selected from the competitive bidding process.

KU will own 61 percent of the array and LG&E the remaining 39 pe rcent — a split based upon the relative load of the two utiliti es during daylight
hours.

LG&E and KU will continue maintaining a diverse generation portfoli o and are continually evaluating potential energy supplies t o determine which available sources would allow the company to sufficiently provide safe, reliable, least-cost energy using commercially availabl e technologies.
