Lower Emissions and Increase Revenue

Emissions Control Systems

Retrofit an existing generation asset with an Energy Choice emissions control system to reduce your energy costs and take advantage of significant financial incentives.

Energy is a major cost in maintaining financial health and competitiveness in any business. Many components that make up your energy bill, like demand charges, are increasing year after year as a result of transmission constraints and the retirement of many traditional power plants.  Retrofitting existing backup power generators with an Emissions Control System will allow the existing asset to be run at specific times during the year for additional hours.

The Energy Choice Retrofit Program

The Energy Choice retrofit program provides an easy and painless process to start managing your energy costs and start generating revenues as soon as possible. The process includes: project evaluation, finance options. installation, testing, permitting, overall project management, reporting, and a support and service team.

Regional incentives for running onsite power generation will turn these systems into revenue producing assets, through a cost effective one-time investment.

There are two ways customers benefit:

Demand Management: Demand counts for 20% or more of your bill. By activating engines during projected peak demand periods you can lower demand and as a result energy costs.  Based on the territory where facility is located, this can be a quick and cost effective solution providing savings and price predictability.

Demand Response: Retrofitting engines with emissions control systems allows existing engines to enroll in DR programs. By serving as a virtual energy plant, you will be paid by the grid operator for reducing electricity use.  Depending on the type of program, participants may be dispatched just once or twice a year for a few hours, or up to 100 hours per year. The more frequently dispatched programs typically offer higher payouts.

What is an Emissions Control System?

Emission limits are continuously reduced worldwide for stationary engines through new state and/or federal legislation.  In order to comply with new emissions requirements, all new engines will require active exhaust-gas treatment.  Older diesel and gas stationary engines initially permitted for emergency generation require exhaust-gas treatment to re-permit for non-emergency use.

The technology used to reduce emissions to the new standards consists of one or two main components, depending on fuel type.

SCR

For gas and diesel generator retrofit projects, the first component in an EC system is a Selective Catalytic Reduction (SCR) system. A SCR system injects a liquid agent like urea (DEF) through a catalyst into exhaust to set a chemical reaction to reduce NOx and CO by up to 97%.  DEF is a non-toxic fluid composed of purified water and urea.  SCRs are successfully used today to reduce emissions on power generation engines, turbines, industrial boilers and diesel automobiles.

For diesel generators, the second component that an EC system contains is a Diesel Particulate Filter (DPF). A DPF is utilized to reduce the amount of fine particles that are produced by a diesel engine. These systems are used in combination with an Energy Choice SCR to provide a complete package that allows existing diesel asset to meet the increasingly strict state and federal emissions standards. Energy Choice’s emissions control systems are a customized, complete packaged system to allow for lower costs and quick installation.  It includes an emissions analyzer, dosing system, catalysts, filtration elements, urea tanks and all necessary accessories and components.
