Energy Efficiency Programs See All

Energy efficiency programs secure energy savings through various strategies such as audits, retrofits, training for building tradespeople, “people-centred” or behavioural efficiency strategies, and customized industrial programs.

Energy Efficiency Program Administration

Efficiency Nova Scotia administers electricity and non-regulated fuel programs in Nova Scotia. Efficiency Nova Scotia was established as an independent, non-profit corporation in 2010, becoming Canada's first 'energy efficiency utility'. In 2014, the government converted the role of demand-side administrator to a franchise, granted for the first 10 years to EfficiencyOne (the former Efficiency Nova Scotia corporation).

Electricity efficiency programs are funded through rates, and subject to oversight by the Utility and Review Board (UARB). Non-electric programs are primarily funded by the provincial and federal governments, and are governed by fee-for-service agreements with the Province.

Energy Efficiency Targets

In Nova Scotia, electricity savings targets are approved by the Nova Scotia Utility and Review Board, under the current 2020-2022 demand side management plan. Non-electricity targets are published in the Efficiency Nova Scotia business plan.

There are no targets in policy or regulation.

Energy Efficiency as a Resource

An Act Respecting Electricity Efficiency and Conservation (2014) established Efficiency Nova Scotia as an “energy efficiency utility” that acts as an independent franchise with the exclusive right to supply electricity and conservation to Nova Scotia Power Incorporated.

The act states that Nova Scotia Power “shall undertake cost-effective electricity efficiency and conservation activities that are reasonably available in an effort to reduce costs for its customers” (Section 79(I)(1).  This does not mean all cost-effective DSM. The Act further states that the utility board takes into account “affordability” to customers (Sect 79L(9)). Affordability (i.e. rate versus bill impacts) is not defined.

Varying levels of DSM investment in the near to mid-term are examined during the development of an Integrated Resource Plan (IRP).  There is no fixed schedule for IRPs in Nova Scotia, but they are generally completed every 3-5 years.  Efficiency Nova Scotia supports the IRP process by developing DSM Potential Studies in advance of each IRP.

In early 2021, Nova Scotia Power released its final Integrated Resource Plan, which included deep decarbonization scenarios.

Efficiency Potential Study and Energy Planning

NS Power completed an Integrated Resource Planning process, which began in 2019 and ended in 2020. The documents connected with this IRP Process are available here. 

This IRP delved further into Distributed Energy Solutions, Electrification Activities, and Demand Response. Base DSM levels (about 130 GWh per year) were used to produce the resource plan with the lowest income demand. Demand Response levels of around 70 MW were also chosen.

Since an IRP was just completed, current expectations in Nova Scotia are for another IRP to be completed within the next 3-5 years.

Cost-Effectiveness Testing

Primary test: Total Resource Cost Test
Secondary test: Program Administrator Cost Test 

The Total Resource Cost Test, at the program level, is the principal screening tool for cost-effectiveness, and the Program Administrator Cost test is reported for informational purposes in DSM plans.  

Non-energy benefits are not included in the TRC.  The Nova Scotia Utility and Review Board has ruled (M08888, Letter 80859) that it does not possess the jurisdiction to allow inclusion of non-energy benefits in the TRC.

Efficiency Nova Scotia is currently exploring the addition of carbon market effects (market price of carbon) as an additional avoided cost within cost-effectiveness testing, by request of the NSUARB. Findings and recommendations are expected within 2021.

Enabling Policies See All

Enabling policies refer to policies, regulations, and other activities that build supportive infrastructure and policy frameworks to advance energy efficiency in a province. 

Support for Financing

PACE Financing
The Municipal Government Act was amended in 2010 to authorize PACE loans. Section 81A enabled municipal councils to make by-laws to enforce charges on private property, with the consent of the property owner and section 65(aca) notes the potential to finance energy efficiency equipment installations, including solar panels.

Starting in 2013, a Halifax program called “Solar City” financed solar hot water installations through a local improvement charge. This was the first program to use LIC funding on a large scale, supported by the Canadian Federation of Municipalities Green Municipal Fund.

PACE financing programs are now available in over 10 municipalities in Nova Scotia. The Clean Energy Program, operated by the Clean Foundation, provides PACE financing in the Town of Bridgewater, District of Lunenburg, District of Digby, District of Barrington, District of Yarmouth, Municipality of Cumberland, and the Town of Amherst, and other municipalities offer it through other organizations, with support from the government.

Efficiency Nova Scotia’s My Energy Improvement Plan PACE Program offers full design, implementation and administration of PACE on a not-for-profit basis.

The Town of Bridgwater is exploring program expansion opportunities to allow even deeper energy retrofits through the Clean Net Zero program, which is currently in the pilot phase.

PACE Atlantic CIC was founded in May 2020 under Nova Scotia’s trailblazing legislation for Community Interest Corporations. Community Interest Corporations (CIC) are a unique form of private incorporation that operate between the 100% for profit and the non-profit world. They operate with a mandate to provide a public good and the requirement to reinvest 60% of distributable profit for community benefit.  

Programs

In the non-residential sector, Efficiency Nova Scotia offers on-bill financing options for non-residential customers, as well as financing options for the Home Energy Assessment program for residential customers.

NS Power also offers on-bill financing for heat pumps, with terms ranging from three to 12 years at an interest rate of 7%. More details are available at https://www.nspower.ca/your-home/energy-products/heat-pumps/financing

Lead by example

Buildings
As of November 2008, all building construction financed by the government of Nova Scotia will be designed and constructed to a minimum LEED Silver standard, an energy efficiency improvement 35% above the 1997 Model National Building Code. Buildings must also provide a post-occupancy comparison of target efficiencies.

Efficiency Nova Scotia’s Onsite Energy Management program includes benchmarking participatory organization’s energy use against similar organizations - Housing Nova Scotia, Nova Scotia Health Authority and TIR Buildings.

The NS Department of Transportation and Infrastructure Renewal is using Energy Star Portfolio Manager to benchmark nearly 80 department owned buildings as part of the Energy Conservation Program.1  This benchmarking initiative is associated with a building recommissioning project.

Vehicle Fleets
An April 2013 Strategy “Choose how you move” states that it will require provincial infrastructure initiatives, including buildings, schools, road facilities, to be planned, located, and designed in a way that supports sustainable transportation goals. 

ReThink: Greener Choices at Work is an internal government sustainability initiative that proposes active transportation infrastructure in government buildings (e.g. bike racks and showers), encouragement of active and public transportation, and managing fleets by right-sizing and purchasing best-in-class vehicles and exploring shared resources between departments.

Grid Modernization

Advanced metering
Regulatory actions related to Nova Scotia’s AMI initiative began in 2015, with the installation of meters starting in 2019. Nova Scotia Power’s $133 million AMI initiative is currently underway, with plans to have all meters be smart meters by 2021.

Non-wires alternatives / Geo-targetting
In 2016 the Nova Scotia Utility and Review Board (NSUARB ) ordered EfficiencyOne and NS Power to begin investigating non-wires alternatives and locational DSM (geotargeting) techniques. Three reports on the topic have been provided under board proceeding number M07815, and provide conceptual design information and proposed preliminary techniques for economic comparison.

 In 2020 NS Power produced updated avoided costs of transmission and distribution reports, which are available publicly at the NSUARB. These avoided costs provide an enabling key piece of information for the development of further locational DSM activity in Nova Scotia.

Work continued on the locational DSM (“Klondike”) pilot in 2020, for customers in the Kentville area. Enhanced incentives were provided through five existing Efficiency Nova Scotia programs. Outcomes were negatively impacted by the COVID-19 pandemic, and the pilot has now closed. Evaluation is scheduled to take place in 2021.

Conservation voltage reduction
Conservation voltage reduction is not used in Nova Scotia.

Other
Active demand response is currently in the investigation stage in NS - 2019 DSM Potential Study will include active demand response. NS Power is currently testing both distribution-scale and behind-the-meter battery storage as part of the Intelligent Feeder Project, as well as certain other smart grid technologies. NS Power historically participated in the Power Shift Atlantic project, which investigated demand response techniques.

In recognition that the industrial sector is highly varied across Canada, this database tracks policies that are broadly applicable to all industrial subsectors and provinces.

Energy Management

Efficiency Nova Scotia reported three industrial energy management programs: The Strategic Energy Management (SEM) program, the Energy Management Information Systems (EMIS) program, and an energy management program specifically for large industrial customers.

The SEM program is designed to work with industrial customers to help customers to find savings through operational and behavioural changes, while identifying capital projects that can be incentivized through Efficiency Nova Scotia’s Custom and Business Energy Rebate programs.

These programs are informed by the SEP-50001 and the International Performance Measurement and Verification Protocol (IPMVP). They do not require certification to receive the incentives.

Co-generation / Combined Heat and Power

Efficiency Nova Scotia (ENS) provides business program participants with technical and financial support for demand side management projects through the Custom program – this includes behind the meter combined, heat and power (CHP).

Financial support for CHP is the same incentive formula used for other efficiency measures through the Custom program. Custom program incentives are calculated based on electrical-utility energy offset by a CHP system, project cost and the participant’s required financial hurdle. Incentives are currently not based on non-electric energy saved or utility electrical-peak demand. Custom program incentives can be used by a participant to offset the cost the third-party feasibility study and/or towards the implementation of a system.

ENS supports CHP systems from micro to several megawatt (MW) plants – done on a case by case basis. All CHP systems must be behind the meter and thus net-metering, feed-in tariff arrangements are not eligible for the ENS Custom program. Technical support is provided by ENS’s engineering team including but not limited to:

  • Pre-feasibility analysis which includes estimating the right system size based on: application and utility/fuel bills;
  • Support defining third-party feasibility scope of work;
  • Review of third-party feasibility studies for accuracy; and
  • Independent measurement and verification.

ENS would require that a variety of system sizes be explored in the third-party feasibility study to ensure a likely success of a participant moving forward with investment. If a participant wants to explore the largest possible CHP system behind the meter we would require that the third-party feasibility study right-size a system by looking at facility electrical-demand and thermal load requirements. ENS strongly advises participants to factor future efficiency measures in the right-sizing of CHP; however, do not require it.

ENS does not support combined, heat and power systems unless there is a green-house gas emission reduction as a result of fuel-switching (utility electricity to on-site generation). Thus, this limits the use of fuels for a CHP system. However, ENS does not provide incentives or require the use of renewable fuels.
