Renewable Resources

From solar power to methane (landfill) gas, JEA is committed to supporting more sources of renewable energy. We are currently studying the possibility of expanding our solar footprint with new offerings and expect the City will eventually allow us to burn biomass, which we are equipped to do. For more details on the mix delivered to our customers, please see our Power Source Disclosure

Solar 

JEA currently receives approximately 22,430 megawatt-hours (MWh) of electricity a year from a solar farm located near Baldwin and owned by PSEG Solar Source, LLC. This is enough energy to serve approximately 1,450 households. This 12 megawatt (MW) facility consists of approximately 213,000 photovoltaic panels on a 100 acre site. JEA receives all the electricity from the solar farm and makes all of the environmental attributes (Renewable energy Certificates or RECs) from this facility available to sell in order to lower rates for our customers. 

As part of JEA’s continued commitment to the environment, we will be adding 32 MW of utility scale solar electric generation capacity to our existing solar generation by the end of 2017. This will bring JEA’s total solar energy portfolio to 44 MW which is equivalent to powering 6,230 homes.

Biogas

We use the methane gas produced as part of the wastewater treatment process at our Buckman Wastewater Treatment Facility to help operate the Buckman Biosolids Management Facility (BMF). The Buckman BMF converts sewage sludge from all JEA treatment facilities into fertilizer for beneficial land application and nutrient recovery. At the BMF, methane gas has been used to supplement natural gas used in the dryer and run boilers, as well as power an 800 kW reciprocating, lean-burn engine that produces power and heat. 

Landfill Gas

Large municipal landfills produce gas that can be tapped to generate electricity. Microorganisms that live in organic materials such as food wastes, paper or yard clippings cause these materials to decompose. This produces landfill gas, typically comprised of roughly 60 percent methane and 40 percent carbon dioxide (or CO2). 

We can pump landfill gas when available from the North Landfill to the Northside Generating Station to generate power at Northside Unit 3.

Through a power purchase agreement with Landfill Energy Systems (LES), we receive energy from a 9.6 MW landfill gas-to-energy facility at the Trail Ridge Landfill in Jacksonville. The facility is one of the largest landfill gas-to-energy facilities in the Southeast, providing enough renewable energy to supply electricity to approximately 4,550 homes. JEA currently makes all of the environmental attributes (Renewable Energy Certificates, or RECs) from this facility available to sell in order to lower rates for our customers.

Wind

As part of our ongoing effort to use more sources of renewable energy, we entered into a 20-year agreement in 2005 with Nebraska Public Power District (NPPD) to participate in a wind generation project located in Ainsworth, Nebraska. Under the wind generation power purchase agreement, we will purchase 10 MW of capacity from NPPD’s wind generation facility for a 20-year period. In turn, NPPD buys back the energy at specified on/off peak charges. JEA retains the rights to the environmental attributes (renewable energy credits, or RECs). JEA currently makes all of the environmental attributes (Renewable Energy Certificates, or RECs) from this facility available to sell in order to lower rates for our customers. 

Biomass

Biomass is organic material made from plants and animals. Biomass contains stored energy from the sun. Biomass is a renewable energy source, because we can always grow more trees and crops, and waste will always exist. Some examples of biomass fuels are wood, crops, manure and some garbage. When burned, the chemical energy in biomass is released as heat.

Renewable Energy Certificates

Each year JEA chooses to sell a portion of the renewable electricity (in the form of Renewable Energy Certificates, or RECs) generated from the renewable facilities in our portfolio. These sales are to entities outside of the municipality, who wish to purchase renewable energy but may not be able to readily purchase it through their electric utility. A REC represents 1,000 kilowatt-hours of renewable electricity generated - meaning for every 1,000 kWhs of electricity produced from a renewable generator, one REC is created. Electricity stripped of RECs, such as solar energy sold to specific customers, is no longer considered renewable as that electricity's environmental attribute has been sold. Revenue from the sale of RECs is used to offset the higher cost of renewable generation.
