History

Tecogen's history is characterized by product development in gas-engine-based power and heat recovery systems and expanding services around installation and long-term support. Over time the company has introduced modular CHP units and side-product families such as chillers (Tecochill/Tecofrost) and emissions-control systems (e.g., Ultera-style technologies). Key historical milestones that typically appear in public filings and company releases include founding and early commercialization, product launches, strategic distribution partnerships, and any transition to public listing.

For specific milestone dates, public filings and press releases maintained on the company's investor relations page and the U.S. Securities and Exchange Commission filings are the primary sources to consult.

Business segments and products

Products segment

Tecogen's principal product families generally include:

• Gas-engine cogeneration/CHP modules: Modular units that generate electricity on-site while capturing waste heat for space heat, hot water or process needs. These systems are often sized for commercial buildings, multifamily housing, hotels and light industrial customers.
• Industrial chillers: Branded solutions for refrigeration and process cooling (commonly referred to with product names such as Tecochill or Tecofrost in company literature).
• Emissions-control products and upgrades: Technologies designed to reduce emissions associated with gas engines and to help customers meet local environmental requirements.
• InVerde and TecoPower-style product lines: Variants of cogeneration or distributed-generation equipment adapted for specific markets or energy configurations.

Typical applications for these products include hospitals, hotels, food processors, laundries, data centers and other facilities with continuous or predictable heat and electricity demands.

Services segment

Service offerings are a major part of Tecogen’s business model and usually include:

• Installation and commissioning of CHP and chiller systems.
• Operations and maintenance (O&M) programs and long-term service contracts.
• Spare parts supply and technical support.
• Retrofit and upgrade services to improve efficiency or emissions performance.

Recurring service revenue can help stabilize cash flow relative to project-based equipment sales, but service margins and contract terms vary by geography and customer.

Energy Production segment

In addition to equipment sales and services, Tecogen may own or operate distributed-generation projects where the company sells electricity or thermal energy under commercial arrangements. These projects are typically small-scale, customer-proximate installations tied to long-term energy service agreements. When present, revenue from energy sales is reported alongside product and service revenues in periodic financial statements.

Technology and R&D

Tecogen’s core technology centers on gas-engine-driven CHP and complementary thermal management systems. Key technology themes usually include:

• Gas-engine CHP integration that maximizes fuel-to-power-plus-heat efficiency for on-site applications.
• Engine-based chillers and refrigeration that leverage recovered heat and modular design.
• Emissions-control systems that address local regulatory limits for NOx, CO and other engine emissions.

The company invests in R&D to improve efficiency, reliability and emissions performance; it sometimes references proprietary control systems and patented components in public materials. For any claims about patents or specific proprietary technologies, refer to the company’s SEC filings, patent databases and formal product briefs.

Markets and customers

Tecogen addresses commercial, institutional and light-industrial markets. Typical customer segments include:

• Commercial buildings and campuses.
• Multifamily residential complexes.
• Hotels and hospitality facilities.
• Food processors and cold-storage facilities.
• Data centers and mission-critical facilities requiring reliable on-site power.
• Municipal and institutional customers like hospitals or universities.

Geographic reach is primarily U.S.-focused with potential international sales depending on distribution partnerships. Sales channels commonly include direct sales, dealer networks and engineering partners for design and installation.

Revenue and profitability

Investors typically review the company's most recent quarterly and annual financial statements to track revenue trends, gross margin and net income or loss. For companies in the distributed-generation equipment space, revenue can be lumpy due to project timing and backlog, while service revenue provides recurring elements.

Balance sheet and cash flow

Key items to monitor include cash and cash equivalents, short- and long-term debt, accounts receivable and inventory levels, and free cash flow from operations. Small-cap industrial companies sometimes rely on equity raises or debt facilities to fund growth; therefore liquidity items and any material changes to credit facilities are important to review in filings.

• Customer concentration and project timing: Large project wins or losses and timing of installations can create revenue volatility for small-cap equipment providers.
• Profitability track record: Many equipment manufacturers show variable profitability as they scale; monitor whether Tecogen is achieving consistent margins and positive operating cash flow.
• Liquidity and market volatility: Shares of smaller companies may experience low liquidity and higher price swings, which can amplify market risk for tgen stock holders.
