Current report

In April, 2024, Tecogen moved it's manufacturing operations and corporate offices from 45 First Ave, Waltham, MA to 76 Treble Cove Road, North Billerica, MA. As a result of the move, product revenues were impacted during the second quarter of 2024. The factory move also necessitated construction activities to install equipment test cells and comply with local regulations. The Company will be able to resume manufacturing operations during the third quarter of 2024.

Current report

In some key markets such as New York City, the regulatory push to eliminate fossil fuels from buildings has impacted cogeneration unit sales. The Company believes that as regulations take into account scope 2 emissions, products like our hybrid chiller that can choose the cleanest fuel source will have a significant advantage in decarbonization efforts.

Impact of Utility Power Constraints and Data Center Construction

Current report

As more load is added to the utility grid in the form of data centers, EV charging, customers are facing power constraints. Tecogen believes that these power constrained customers, in particular data centers and industrial facilities represent a significant opportunity for growth. The customer need is driven by ability to expand an existing facility or open a new facility quickly while taking advantage of utility bills savings long term. Our chiller products can reduce the electrical capacity needed on-site by 30% or more. Our InVerde product can provide on-site power generation by using an inverter based system that operates at 480V. This allows customers to eliminate long lead times associated with electrical switch gear and bridge any short fall in power from the utility.

Current report

Supply chains were adversely impacted during Covid resulting in significant delays or lack of availability of critical components such as engines. This has continued to have long term impact on product and service margin. The direct impact has been certain costs increasing faster than inflation. The indirect impact is from increased engine related costs in the service segment as replacements were deferred or overhauled components were used due to lack of parts. We have instituted a service price increase and have also been making engineering improvements to increase service intervals to increase margins.
