Paralleling, Peak Shaving & Global Adjustment Abatement
Sommers paralleling generator line offers a self-contained, economical way to parallel up to 32 generators. This provides back-up and alternative power to assist with Peak Shaving and Global Adjustment Abatement strategies.
Advantages of Paralleling Generator Systems
Sommers paralleling generator line offers a self-contained, economical way to parallel up to 32 generators.
Our designs are compatible with different size generators (kw), fuel types and flexible enough to be installed with other brands. This strategy reduces installation time on-site by incorporating the necessary synchronization control and motorized breaker into one ready-to-use package
Advantages of running multiple generator sets, paralleled:
Redundancy to their emergency power system
If one set fails, you can modify operations to continue running on the other sets until service arrives.
Load sharing: If your operation encounters load swings, load sharing works by monitoring your current load and adding or removing generators as they’re needed
Reduces wear, and fuel consumption while our controls rotate generator sets between the master and slave to ensure equal hours on each system.
Paralleling up to 32 generator systems, diesel or gaseous, produces long term savings to the customer.
The differences between the wholesale market price for electricity, known as the Hourly Ontario Energy Price (HOEP) and Regulated rates for Ontario Power Generation’s nuclear and hydroelectric generating stations
Payments for building or refurbishing infrastructure such as gas-fired and renewable facilities and other nuclear, as well as the contracted rates paid to a number of generators across the province
The cost of delivering conservation programs
The GA varies from month to month, responding to changes in the HOEP compared to contract prices. Generally speaking, when the HOEP is lower, the GA is higher to cover additional costs for the items referenced above.
The GA rate is also impacted when new projects come into service, contract payments take effect or as a result of changes in Ontario electricity demand.
The IESO’s Monthly Market Summary reports contain month-by-month information on the various components of the Global Adjustment.
Understanding Global Adjustment
Consumers who pay market prices or have signed a retail contract for electricity will see a line for Global Adjustment (GA) on their electricity bill.
The GA was established by the Ontario government in 2005 to cover the cost of providing adequate generating capacity and conservation programs for Ontario.
The Global Adjustment may be a positive or negative number, depending on whether the Hourly Ontario Energy Price (HOEP) is higher or lower than the fixed rates.
Opportunities for significant savings
Using back-up generators to curtail demand is not a new concept; for several years, customers who have environmentally approved generation capacity have been shaving their peaks by generating their own power. The difference now is that the use of generators is becoming more prominent as the 5CP and other DR programs provide an accelerated payback of the initial capital costs. Every kW of generation output during a peak hour has the same net benefit in reducing your GA costs than as a reduction in the consumer’s load itself.
Consumers wishing to utilize existing generators, or considering the purchase of new ones, must consider the additional costs of running the equipment during peak hours and ensure they have the appropriate environmental certification that allows them to use it for this purpose. In some cases, customers with existing backup generators may simply upgrade their equipment to meet the environmental certification requirements.
In an effort to reduce the overall cost of energy demand charges, a strategy is utilized to smooth out peak loads, called Peak Shaving. Short-term demand spikes set a higher peak usage and eliminating these by utilizing an alternative power source manages the overall demand.
Businesses can be charged penalties for high electrical use during periods of high demand on the energy grid. Utilizing generator power can replace or supplement grid power during peak production periods to avoid costly penalties. At Sommers, we will assess your needs to provide recommendations and support you through installation, maintenance and emergency support.

Consult utility bills for actual consumption patterns
Global Adjustment (GA) costs charged by utilities are assessed according to energy consumption during specific sampling periods. GA Abatement strategies use off-grid power to reduce demand during the assessment dates. Sommers can implement GA Abatement strategies tailored to any facility:
Supply and maintain rental systems during target periods
Recommend and train facility staff to operate purchased or leased equipment
“Power by the hour” turnkey solutions in collaboration with the local utility
Calculating your Peak Demand Factor
A customer’s PDF is based on their percentage contribution (i.e., the quantity of energy withdrawn from the IESO controlled grid or distribution system of a local distribution company) during the top five peak hours of the corresponding base period.
Calculating your Global Adjustment
The Class A customer's PDF is used to calculate their monthly GA charges during the adjustment period (i.e., billing period). A Class A customer’s GA charges are calculated by multiplying the total monthly GA costs by the customer's PDF.
By utilizing peak shaving and investing in generators for alternative power, companies can save on their GA charges while also having backup power for emergencies.
