Reducing dependency on diesel in Canada’s North

SITUATION

Northern and remote Canadian communities are actively looking to address challenges of energy security.

Dependent on an ageing fleet of inefficient diesel generators, Canada’s northern communities face a constant risk of generator failure and power outages. Furthermore they depend on costly diesel fuel that must be transported to northern communities using ice roads. Further complicating the situation, climate change has resulted in smaller windows of opportunity to transport fuel. [use image of truck sinking in ice]

One key to Canada’s strategy for achieving northern energy security is reducing the north’s dependency on diesel to generate electricity. Focus is on increasing the use of renewables such as Solar, wind, hydro, and battery storage to power northern communities.

Unfortunately it’s going to take time for renewables to reach penetration levels required to fully replace diesel. Additionally, battery storage, which is required to stabilize renewables operating with fixed speed generators, comes at a high financial cost.

Given the challenges in the north, how can communities bridge the shift away from Diesel generators?

INNOVUS-POWER’S VARIABLE SPEED GENERATOR SOLUTION

Innovus-Power’s variable-speed generator (VSG) technology offers immediate reductions on Diesel requirements, while promoting the deployment of renewables. The Innovus VSG Microgrid controls allows our VSGs to pair with all renewable power system. Our Microgrid controllers automatically adjust the speed of the VSG up or down (and if needed, completely off) depending on load and the amount of electricity being supplied from the renewable.

Compared to a standard Fixed Speed Generator, the Innovus VSG offers fuel savings ranging from 15% without renewables to 45% with high penetration renewables.

A COST-EFFECTIVE SOLUTION TO NORTHERN ENERGY SECURITY

When you talk about cost of energy, our technology is much less expensive than existing fixed speed generation technologies. We deliver a significant cost reductions on fuel, operations and maintenance and pollution.

Since the majority of the components in innovus generators are similar to those in fixed speed generators, the innovus solution’s initial capex comes at only a slight premium to buying Fixed Speed Generators. Furthermore, fuel savings, extended service intervals and reduced maintenance costs provide clients with a short payback period.

Reduced fuel consumption, less pollution, and lower operating & maintenance costs – all while helping grow the use of renewables. Innovus-Power Variable Speed Generator Solutions offer a real solution to energy security challenges in Canada’s North.

Western Australia – Converting High Cost Utility Customer to Solar PV – Diesel Hybrid Microgrid

By deploying Innovus Power’s hybrid microgrid technology over $393,000 in savings per year over the Utility can be achieved! That’s an additional $196,000 over the EPC’s traditional hybrid microgrid solution.

SITUATION

An Engineering Procurement and Construction (EPC) company is working with a Western Australia truck stop operator to lower their rapidly escalating energy costs by taking them off-grid. This respected EPC has over a decade of experience with successful hybrid microgrids and when the truck stop operator approached them to help, the EPC looked at number of solutions.

SOLUTION

The EPC asked Innovus Power to model their traditional solution against the Utility baseline and our microgrid platform. We used Homer Energy’s modeling tools and our own sophisticated Levelized Cost Of Energy (LCOE) financial model to study the different scenarios. We looked at the EPC’s standard microgrid solution which includes batteries for grid stability, 350kW of solar PV and fixed speed generator sets. Next we looked the Utility costs, taking care to evaluate the rising costs over the projected project lifetime of 20 years. Lastly we modeled Innovus Power’s variable speed generator sets with the same 350kW of solar PV and our Power Bridge energy buffer allowing engine off operation of the microgrid.

We account for install costs, O&M, fuel escalation, solar degradation, utility escalation and financial load, etc. over the life of the 20 year project to derive a true LCOE for each scenario. The results speak for themselves.

Sandpoint, Alaska – Wind – Diesel Hybrid Microgrid

SITUATION

TDX Power operates several regulated utilities in the state of Alaska. Currently their wind-diesel operation at Sandpoint has a 1 MW of wind capacity and four fixed speed diesel gensets for power surety. Sandpoint suffers from frequency instability issues and is forced to severely curtail the wind assets to 20% capacity.

SOLUTION

Innovus Power will be installing, later this summer a single IP MVS 600 Variable Speed Generator Set and PowerBridge our ultra-capacitor based Energy Buffer with secondary load capabilities. By producing a stable constant frequency, our inclusive hybrid microgrid solution solves all of TDX’s frequency issues and dramatically reduces the cost of energy.

TDX will be able to deploy the full capacity of their wind assets and realize a >50% reduction in diesel costs. At today’s fuel prices that equates to $525,000 a year in savings!

SITUATION

A Caribbean commercial site struggles with high local utility prices and tariffs. Before start of service, the utility demanded a deposit equal to 6 months estimated energy usage which they hold interest free .  The business owners urgently seek to lower energy costs and seek alternative sources of power.

OUR ANALYSIS

We studied multiple scenarios using Homer Energy’s hybrid microgrid modeling software which allowed us to study literally thousands of microgrid systems scenarios.  We looked for a system with the lowest cost of energy (LCOE).  Homer came up with multiple scenarios including Fixed speed gensets, Innovus Variable Speed gensets, Solar, batteries, and converters. Factoring in cost per kW, maintenance, cost of fuel, solar resources, load profile and numerous other inputs, Homer came up with three system scenarios recommending the Innovus Variable Speed Genset and lowered the LCOE by $.06 kWh with our genset alone.

Dramatic Savings In Remote Community Power Generation

Unique Benefits of Variable Speed:

  • Higher fuel efficiency, in this case over 12%.
  • Significantly lower operating and maintenance costs than fixed speed generator sets.
  • Effortless integration of renewable resources.
  • Ability to run at 10% of generator set capacity without detriment to the engine or fuel economy.
  • Inclusive System Control And Data Acquisition (SCADA).
  • No paralleling equipment required.
  • High quality, stable power output regardless of engine RPM.

SITUATION

A power generation utility serving thousands of residents in remote, off-grid communities has been struggling to show more than minimal efficiency gains in power plants distributed across hundreds of miles of territory.  Their current non-integrated and off-grid power networks consists of multiple sizes of fixed speed generator setss based on an 85 year old network design where additional capacity was manually added.  This created inefficient trade-offs between capacity and efficiency.    Manual processes or economic dispatch  had also resulted in unavoidable operational complexity, maintenance and operational costs over many decades.   Even single digit fuel efficiency gains were difficult to achieve and the company could see no easy path to improve the situation in the short term or to integrate plans for renewables longer term.

OUR ANALYSIS

Based on an annual load profile, we validated a significant potential fuel & emission savings versus current technologies and techniques.  Fuel savings alone showed an investment ROI of just 4 years, and factoring in extended time between service and overhauls and the elimination of additional paralleling gear created a very attractive financial proposition.  We also showed a clear way to incorporate renewables into the network without integration headaches or costly storage solutions.

Substantial Fuel Savings For Artificial Lift Operations

Unique Benefits of Variable Speed:

  • Delivers significant fuel reduction of 18-20%.
  • Produces superior power quality, extending the service life of down-well motors.
  • Reduces engine wear and tear over fixed speed systems, the engine never runs at high RPM with light loads.
  • Extends service and overhaul intervals of up to 25%.
  • Furnishes redundancy of the complete power system from the Variable Speed Genset to the pump motor
  • Provides integral VFD and motor controls.

SITUATION

An international oil and gas titan was recently looking for dependable, high quality power to run their Electrical Submersible Pumping (ESP) operations. Current fixed speed generator sets could not keep up with the fluctuating load and long distance to the bottom of the well where the pumps reside.
In addition low average loads contributed to maintenance issues and poor fuel economy.   A phase shift transformer and Variable Frequency Drive with power filtering were required to protect the pumps from poor power quality and shortened life cycles. These additional pieces of equipment added capital expense and became single points of failure.  In deep well artificial lift operations, failure of the down-well pump motor can cost over  $350,000 for an extraction, not to mention the lost revenue. It is critical the pump motor be supplied with stable clean voltage and frequency.

OUR ANALYSIS

When we compared variable to fixed speed generator set solutions, our analysis showed dramatic fuel cost and maintenance savings for their artificial lift operations.    Fuel saving alone amounted to $326,000 per well, per year. Our integral phase shift control, Variable Frequency Drive (VFD), and paralleling abilities offered redundancy from the Variable Speed generator set, all the way to the pump motor, with superior power quality.
