At a Glance
• System Configuration: 1 × C65 Grid Connect Capstone Microturbine (65 kW) with microMTIM automated controller
• Annual Generation: >550 MWh/year (>550,000 kWh/year)
• Energy Savings: ~$50,000 / year in reduced utility expenditures
• Thermal Integration: 430,000 BTU/hr of hot water offsetting space and domestic water heating


The Challenge
Managing MTCC 1207 (the 95-unit Lindenwood tower in Toronto’s Distillery District) involved growing financial pressure from escalating utility tariffs. Built in 1998, the building was historically known for low maintenance fees, but rising hydro, gas, and water costs—compounded by aging HVAC infrastructure and general inflation—began straining the operating budget. The condo board needed a proactive energy management strategy to mitigate price risk, improve building energy efficiency, and protect resident affordability by stabilizing monthly maintenance fees.


The Solution
Veristar Energy implemented an advanced Combined Heat & Power (CHP) solution featuring a 65 kW microturbine paired with an automated microMTIM controller for full remote monitoring and performance optimization.
• Onsite Electricity Generation: Generates over 550 MWh of clean electricity annually on-site, directly displacing expensive utility grid purchases and hedging against future hydro rate hikes.
• Thermal Energy Recovery: Recovers 430,000 BTU/hr of high-grade exhaust heat in the form of hot water, supplementing central domestic hot water and space heating loops to slash primary natural gas consumption.
• Automated Operational Control: Integrates sophisticated microMTIM controls for automated dispatch, real-time remote monitoring, and streamlined service management to maximize system availability.
• Infrastructure Relief: Reduces operational load and runtime strain on legacy mechanical systems, helping offset aging infrastructure inefficiencies.


The Results
• $50,000 Annual Bottom-Line Savings: Directly reduces hydro and natural gas expenditures, alleviating upward pressure on monthly condo maintenance fees for all 95 unit owners.
• Utility Price Protection: Establishes a predictable long-term energy cost structure, shielding the corporation from volatile electricity and natural gas market swings.
• Ultra-Low Maintenance Overhead: Utilizes air-bearing microturbine technology with a single moving part, delivering quiet, low-vibration, low-O&M operation ideal for urban mid-rise residential properties.
• Regulatory & Efficiency Alignment: Elevates site-wide energy efficiency, assisting the condo board in meeting modern environmental compliance and sustainability targets.
