Energy Savings Scheme – what is it?

NSW mandatory scheme – established by legislation.
Electricity retailers are the liable parties

Started on 1 July 2009, legislated to 2020*

Market based mechanism that involves the creation
and trading of Energy Savings Certificates (ESCs)

Companies are accredited for implementing projects
which reduce electricity consumption

Certificates currently trading at $25-30/ESC on a spot
market.

IPART – Scheme Administrator (certificate creation)
and Scheme Regulator (compliance by liable parties)

Energy Savings Scheme - genesis

Demand Side Abatement (DSA) Rule of NSW
Greenhouse Gas Abatement Scheme (GGAS) spunoff to become the Energy Savings Scheme (ESS)

GGAS DSA savings were 90% residential

With ESS, one aim was to broaden the scope of
energy savings activities

Energy Savings Scheme
– development of methodologies

Balance between




activity specific factors & formulae vs more generic
methodologies
ex-ante (upfront deeming) vs ex-post certificate
creation
GGAS DSA experience – generic methodologies &
ex-post certificate creation generated modest level of
certificate creation
ESS – increase in activity specific methodologies and
more deeming than GGAS DSA
- Commercial Lighting Formula is one of the new
additions

Commercial Lighting Formula (CLF) –
Key design aspects




Broad coverage & flexible
Adequate lighting outcomes
Simplicity
Accuracy
6
CLF – Coverage and flexibility

Covers all types of commercial/industrial lighting
upgrades (but not ‘greenfield’ lighting installations)

Includes:
– Commercial (industrial) building Lighting
– Lighting of roads and public spaces
– Traffic signals


Covers ‘mainstream’ and ‘emerging’ lighting
technologies (e.g. LEDs)
Includes lighting controls (e.g. occupancy sensors)
7
CLF – Coverage - emerging lighting
technologies – additional requirements (1)

Emerging Technologies found in CLF Guide:

LEDs (Lamps/Power Supply/Integrated Ballast)

T5 adaptor kits

Induction Lamps

Voltage Reduction Units (VRUs)

Meet requirements:

Performance (LCP) – Test Report or Registered
Information

Electrical Safety – Fair Trading

Electromagnetic Compatibility (EMC) – ACMA
8
CLF – Coverage - emerging lighting
technologies – additional requirements (2)
9
CLF – Adequate lighting outcomes

Minimum lighting design requirements
– Exceed AS/NZS 1680 (where it applies) or other
applicable benchmark
– If part of a project subject to a development approval
(DA), can only claim for savings exceeding DA
requirements

Customer engagement process

Demonstration (example) project
10
CLF – Simplicity & Accuracy

Energy savings calculated by comparing the ‘original’
and ‘upgraded lighting equipment, based on:

Calculation
Tool
Lamp circuit power =
Nominal lamp power + Power consumption of control
gear (driver, ballast, transformer)

Lighting controls (e.g. occupancy sensors)

Air conditioning load

Annual site operating hours (default of 3,000 hours)

Asset lifetime (default of 10 years - buildings,12 years - roads &
public spaces, except for ‘lamp only’ replacement)
11
CLF – Simplicity
Calculation Tool
12
Calculation Tool: Benefits

Ensures that the energy savings and number of
certificates are done as per the ESS Rule.

Simplifies administration of lighting upgrade projects.

Generates a report to keep record of the lighting
upgrades performed.
13
Case Study – manufacturing facility (1)

Site-wide Lighting redesign involving various aspects,
including



Replacing 400W metal halide high bays & reactor
ballasts with high efficiency 200W T5 fluorescent
luminaires
Lighting controls e.g. daylight linking, timers, occupancy
sensors
Permanent de-lamping in over-lit areas
14
Case Study – manufacturing facility (2)
The financials

Capital cost of $105,000

Reduced lighting power consumption by 66%

Saving of 405MWh ($64,000) per year

Payback of 20 months
With participation in the ESS

4,293 ESCs (after application of deeming period)

ESC revenue to site of over $75,000

Payback of 5 months!
15
CLF – Experience so far

Experienced lighting operators vs new entrants

Assessing emerging lighting technologies

29 companies accredited to date using CLF

32 different lighting activities

Lighting upgrades at hundreds of sites throughout
NSW

386,000 certificates created to date
