Nova Scotia

Nova Scotia ranked 4th  in Canada’s first Provincial Energy Efficiency Scorecard, earning 45 points out of 100.

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 a fee-for-service agreement with the Province.

Energy Efficiency Targets

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 teh IRP process by developing DSM Potential Studies in advance of each IRP.

Efficiency Potential Study and Energy Planning

Nova Scotia Power has developed Integrated Resource Plans since 2007, with no fixed schedule.  The last IRP was filed in 2014.  A new DSM potential study was completed and filed as part of a new IRP process in August 2019.

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.

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 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.

On-Bill Financing

Efficiency Nova Scotia has credit enhancement features in its Custom Program On-Bill Financing (loan guarantees), Home Energy Assessment Financing Program, and the Affordable Multi-family Housing On-Bill Financing program (both using interest rate buy-downs). The Small Business Solutions On-Bill Financing allows third-party financing. Standard on-bill financing is also available through NS Power for heat pump conversions and electric thermal storage.

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.

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

In the fall of 2019, EfficiencyOne launched a locational DSM pilot at the Klondike Substation in the Kentville area.

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

Rate design
An optional time of day tariff is available for residential electricity customers who employ electric thermal storage equipment.

There is a declining block rate for general and small industrial electricity customers (lower price after a kWh consumption threshold).

Interruptible rates are available for large industrial and extra large industrial customers

Nova Scotia has a fuel adjustment mechanism, which is a mandatory rider applying to many electric rate schedules.

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.[4] NS Power historically participated in the Power Shift Atlantic project, which investigated demand response techniques.

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.
