1. Bluesphere Anaerobic Digester Due Diligence

    A private developer of renewable energy projects hired RETTEW to conduct a due diligence evaluation of a 400-ton-per-day food waste anaerobic digestion facility in Charlotte, North Carolina. The facility receives organic feedstocks from poultry and other food processing operations, pre- and post-consumer food waste from grocery chains, and manure from local farms. The feedstocks are…

  2. Anaerobic Digestion to Renewable Natural Gas Project Development

    An energy client was looking to develop multiple renewable natural gas (RNG) projects to meet their corporate sustainability goal of reducing the carbon footprint of the natural gas grid through RNG. These projects will generate biogas that can be upgraded to RNG on site. The feedstocks for this program are agricultural wastes such as dairy…

  3. Jonah Energy Alternative Energy Offset Analysis

    Jonah Energy LLC operates one of the highest-producing natural gas fields in North America. Jonah Field, in the Green River Basin, is their most active gas-producing site. Oil and gas operations are limited by the amount of NOx and volatile organic compounds (VOC) generated, based on a predetermined emissions bank. Jonah Energy operations uses gas-driven…

  4. Rhode Island Row Solar Array

    A team of solar developers was looking to install rooftop and carport solar arrays on two mixed-use commercial buildings in downtown Washington, D.C. to benefit lower-income residents in the D.C. area. RETTEW was the ideal candidate to make this goal a reality because of our vast experience in designing solar arrays, as well as general…

  5. Bedrock Depth Mapping at a Solar Farm

    A solar farm was expanding onto a hill where a limestone rock outcrop was observed. This raised concerns about shallow rock that could impede installation of the driven rods that support the solar panels. In soil, the rods need to reach a specified depth to prevent wind from lifting the panels. If the rock is…

  6. Atlantic County Utilities Authority Battery Energy Storage System

    As the lead design-build firm that is co-developing battery energy storage system (BESS) projects nationwide, RETTEW implemented this technology at the Atlantic County Utilities Authority (ACUA) Wastewater Treatment Plant. The 1 MW/1 MWhr BESS furthers ACUA’s efforts to implement progressive energy technology at the plant. The BESS supports overall grid operations, reduces greenhouse gas emissions,…

  7. Masonic Village Solar Array

    Masonic Village, Lancaster County’s second-largest retirement community, is committed to solar energy as part of its comprehensive sustainability program. Taking a forward-thinking approach, Masonic Village wanted to build upon their existing infrastructure and see a positive rate of return while meeting their goals to be more energy efficient. Because of our longstanding relationship with Masonic…

  8. Middlesex County Utilities Authority (MCUA) Solar Field Closeout Evaluation

    Approaching the end of an innovative solar field construction project, Middlesex County Utilities Authority (MCUA) needed a closeout evaluation of their solar arrays. The four arrays range in nominal capacity from 249 to 2,306 kilowatts and, when combined, are the second-largest municipal solar generation system in New Jersey at a total of 4.6 MWdc. RETTEW…

  9. Hermitage Food Depackaging Study

    The Hermitage Municipal Authority completed upgrades at their water pollution control plant that expanded wastewater treatment capacity and introduced a two-phase advanced anaerobic digestion (AAD) complex to its current plant operations. This complex optimizes the solids handling train by further promoting biosolids stabilization, biogas recovery, and generating both heat and power. Gas production and power…

  10. Wind Farm Survey

    An energy company leased approximately 10,000 acres from more than 50 separate landowners in three counties to install and operate wind turbines and the transmission lines required to deliver energy to homes across the nation. The company wanted a full-service firm that could effectively and efficiently deliver all aspects of the planned projects on time…
