eNow Inc. designs, manufactures and sells renewable energy management systems. These systems aggregate power from inputs, such as solar, shore power, regenerative brake systems and exhaust recovery systems.

The energy is captured through the various systems and is stored in a battery system. This allows the auxiliary systems to pull power from the charged battery instead of idling the engine to power those systems.

The eNow system manages how the power is produced, stored and used. The systems have been developed to lower the use of fossil fuels, lower the cost of engine maintenance and to reduce greenhouse gas emissions.

In most cases, the payback periods are between one and a half to two years, according to the company.

At their press event during NTEA's Work Truck Show, the company indicated that the system costs around $12,000 initially, but after tax credits and incentives that price is reduced to approximately $8,000.

The systems can be installed at the OEM-level or in an aftermarket capacity.
