Solar@Night is a scalable approach to renewable, clean energy development that is the solution to today’s energy consumption. Renewable sources such as solar and wind are clean and infinite, but are not as reliable and predictable as firm sources like coal and natural gas. However, coal and natural gas release carbon emissions that are harmful to our environment.


Solar@Night combines utility-scale solar farms with traditional, renewable firm power technologies, like biomass, landfill gas-to-energy (LFG), and anaerobic digestion (biogas). The result is blended renewable energy generating assets that resemble their firm power, non-renewable “cousins,” like coal, natural gas and oil. Solar@Night addresses the issue of over reliance on intermittent energy sources by creating renewable energy solutions that produce power around the clock to meet today’s growing energy demands.

Our Solar@Night projects focus on blending three primary firm renewables and intermittent solar technologies:


  1. Solar + Landfill Gas-to- Energy (LFG)
  2. Solar + Anaerobic Digestion (Biogas)
  3. Solar + Biomass


Landfill Gas-to-Energy


Landfill gas collection systems are how modern landfills deal with gases created within the waste. The landfill gas that is collected contains approximately 50% methane (CH4) and is either destroyed by combusting it in a flare or is diverted to an on-site treatment facility for the conversion of this gas to energy. The conversion of landfill gas to energy is an effective means of recycling and reusing this valuable resource.


As landfill cells are filled with waste, methane gas, a byproduct of any decomposing material, is collected from within the waste through a system of vertical wells and pipelines and directed to a separate on-site treatment facility. The methane gas is then treated to remove excess moisture, particulates and other impurities. Once cleaned, the gas is piped to an engine where it is converted into electricity.

Anaerobic Digestion (Biogas)


Anaerobic digestion is the process of collecting waste from livestock or humans, or byproducts from agricultural production. Once collected, an anaerobic digester breaks down the organic matter and methane gas is released. We collect that methane, then send it to an engine where it is converted into electricity.



Biomass is the process of cultivating organic matter or using agricultural byproduct to heat a boiler, which sends steam to a steam turbine.
