MAS Energy

What MAS Energy does

MAS Energy is a privately held, fully integrated investment, development and asset management organization headquartered at 3340 Peachtree Road NE, Suite 170, Atlanta, Georgia. Founded in 2008 and operating with 11-50 employees, the company develops, owns and operates distributed clean-energy generation systems for utilities (investor-owned, municipal and cooperative), private sector off-takers, landfill operators, and developing-nations power providers. Its go-to-market is enterprise field sales targeting long-term project development relationships and power purchase agreements (PPAs).

MAS Energy's core technology portfolio rests on conventional, proven energy-engineering building blocks: combined heat and power (CHP/cogeneration), renewable natural gas from landfill gas (LFG-to-energy across medium-BTU boiler offsetting, high-BTU pipeline injection, and CNG/LNG fueling), reciprocating-engine distributed generation (10-200 MW scalable, fast-start within three minutes, capable of base-load or peaking duty), and hybrid solutions combining battery storage, solar and simple-cycle generation. Underpinning these projects is a self-performance capability covering risk mitigation, contract structuring, capital structuring, project development and operations & maintenance. The wholly-owned Mas Energy Operating Services (MEOS) subsidiary, established in 2017, provides asset management and plant operations across both company-owned and select third-party assets; scale signals for MEOS include 19 sites, 33 engines, ~20,000 SCFM of gas generation and 27 miles of pipeline under management.

Revenue is generated through two streams: (1) Project Development and Ownership, where MAS Energy develops, owns and operates systems and sells energy under long-term PPAs to utilities, municipalities and private buyers; and (2) Asset Management Services via MEOS, which delivers comprehensive oversight including staff supervision, permitting, accounting, financial planning, cash management, insurance and KPI-based monthly reporting. Pricing is custom and quote-based (no public pricing), and the executive team combines Wall Street capital-markets experience (Banc of America, Morgan Stanley, Merrill Lynch, Jefferies, Bear Stearns, RBC) with operational pedigree from GE, Veolia Energy, Johnson Controls, EnerNOC and Southern Company.

Core offering

MAS Energy is a fully integrated developer, owner, and operator of distributed clean-energy generation systems. Its core offerings include renewable natural gas from landfill methane (for electricity, medium-BTU gas, or pipeline-quality CNG/LNG), combined heat and power cogeneration facilities, distributed reciprocating-engine generation (10-200 MW), and ongoing asset management and plant operations delivered through its MEOS subsidiary. The company also performs turnkey development covering risk mitigation, contract structuring, and capital structuring from concept through operation.

Product overview

Mas Energy is a fully integrated investment, development and asset management organization that delivers clean-energy generation systems. The company operates four core products: Renewable Natural Gas (converting landfill methane to electricity, pipeline-quality gas, or CNG/LNG), Combined Heat and Power (cogeneration capturing waste heat), Distributed Generation (reciprocating engine systems 10-200 MW), and Asset Management via Mas Energy Operating Services (MEOS). These are complemented by Turnkey Development services and Hybrid Energy Solutions incorporating battery storage and solar. The company develops, owns and operates energy systems around the world.

Brands

• Mas Energy Operating Services (MEOS): Asset management and plant operations services subsidiary established in 2017, providing comprehensive asset management and oversight at facilities in the MAS Energy portfolio.

Products and services

• Renewable Natural Gas (Landfill Gas to Energy) Converts landfill methane gas into usable energy through direct electricity generation, medium-BTU gas for steam boilers and utility plants, and high-BTU gas for natural gas pipeline injection or CNG/LNG fueling stations. Systems achieve over 90% online reliability and provide long-term price hedging against fossil fuels. Target buyers include landfill operators, utilities, and energy customers seeking GHG reduction.
• Combined Heat and Power (CHP) Cogeneration facilities that capture waste heat from conventional power plants and reuse it to produce both heat and electricity from a single heat source, reducing fuel costs and CO2 emissions. Designed for private sector companies and industrial buyers seeking to lower energy costs and carbon footprint.
• Distributed Generation Customized reciprocating engine-based distributed generation systems scalable from 10-200 MW, capable of operating as base load or peaking plants and able to provide power to the grid within three minutes. Targets utilities, municipalities, and cooperatives needing flexible, fast-starting generation to backfill intermittent renewables.
• Asset Management (Mas Energy Operating Services - MEOS) Comprehensive asset management and plant operations services delivered through MEOS, covering day-to-day operations, commercial contracts with OEMs and parts providers, staff supervision, government filings, permits, accounting, financial planning, cash management, insurance, and monthly KPI-based performance reporting for owned and select third-party facilities.
• Turnkey Project Development End-to-end project development services covering risk mitigation, capital structuring, contract structuring, commercial agreements, project development, and ongoing operations and maintenance for energy projects. Sold to utilities, municipalities, cooperatives, and private sector companies.

Direct peers

• Ameresco: Ameresco is a publicly traded renewable energy and energy efficiency services company that develops, owns and operates CHP, distributed generation, RNG, and energy efficiency projects — closely mirroring MAS Energy's integrated developer-owner-operator model across similar customer segments (utilities, municipalities, private sector).
• Wärtsilä Energy: Wärtsilä manufactures and services flexible, modular reciprocating engine power plants for grid balancing, distributed generation and CHP — the same underlying technology stack that MAS Energy deploys across its 33-engine portfolio.
• OPAL Fuels: OPAL Fuels develops, owns and operates renewable natural gas projects sourced from landfills and digesters, producing both pipeline-quality RNG and CNG/LNG fueling — a direct overlap with MAS Energy's landfill gas to RNG business line.
• Veolia Energy North America: Veolia operates large-scale district energy and CHP systems serving industrial, commercial and institutional customers — directly comparable to MAS Energy's CHP and distributed generation business. Notably, MAS Energy's Michael Hall and Jason Byars both came from Veolia Energy.
• Caterpillar (Cat Energy Solutions): Caterpillar's gas engine and CHP product line (Cat G3500/G3520 series) is among the conventional engine platforms MAS Energy deploys for its 10-200 MW distributed generation projects, making Cat a both supplier and adjacent business model peer.

Broad incumbents

• Capital Power: Capital Power is a North American independent power producer that develops, owns and operates natural gas and renewable generation, including CHP and distributed generation — a broader incumbent comparable to MAS Energy on the developer-owner-operator axis.
• ENGIE North America: ENGIE North America operates a broad portfolio of CHP, district energy, and renewable generation assets serving utilities, municipalities and industrial customers — overlapping with MAS Energy's customer base but at significantly larger scale and as part of a global utility.

Emerging players

• Bloom Energy: Bloom Energy deploys onsite fuel cell power generation systems to commercial and industrial customers — comparable to MAS Energy's distributed generation value proposition of onsite, behind-the-meter clean power, though with a different underlying technology (fuel cells vs. reciprocating engines).
• Brightmark Energy: Brightmark develops RNG from organic waste (including landfill gas) and other renewable energy projects, with a similar project development and ownership model to MAS Energy but focused more narrowly on waste-to-energy.

Others

• Black & Veatch (Energy & Power): Black & Veatch provides EPC and owner's engineering services for utility-scale power generation and renewable projects — overlapping with MAS Energy's project development and asset management capabilities, but as an EPC/infrastructure services provider rather than an asset owner.
