BC Hydro's two-step rate

BC Hydro's two-step rate encourages conservation
September 9, 2008
By Bob EltonBC Hydro President and CEO
Conservation is the cleanest, easiest and least expensive way to meet the increasing demand for electricity in B.C. – it's like building a virtual dam. That's why BC Hydro is introducing a two-step rate for our residential customers to provide a financial incentive to conserve.
With the new conservation rate in place, 70% of BC Hydro's residential customers will pay the same or less than with the existing flat rate – even if they take no action to conserve. Of course, we hope people will take action, in particular, consumers with high electricity use.
How the conservation rate works
Close to 20 North American utilities already have stepped residential rates that work much like BC Hydro's. Here's how ours will work: As of Oct. 1, customers will pay 5.98 cents per kilowatt hour up to 1,350 kilowatt hours of electricity used over a two-month billing period and then 7.21 cents for electricity used above that amount. In April of next year, the step-one rate will become 6.35 cents and the step-two rate 8.27 cents.
A fair, equitable rate
It's interesting to note that half of our residential load goes to serve just one quarter of our customers. But we believe everyone has a role to play. That's why the two-step conservation rate will apply equally to all residential customers – regardless of the kind of house they live in, how they use electricity, or where they live.
When you look around the province, consumption is very similar. The number of high-consumption customers in the Lower Mainland, for example, is about the same as the number on Vancouver Island – even though natural gas arrived on the Island only a few years ago and there are a higher proportion of electrically heated homes.
While electric heat can be one significant use of electricity, consumption is driven by a wide variety of factors – for example, dwelling size, the energy efficiency of household appliances, and lifestyle choices such as the number of electronic devices.
We all have the power to conserve
Whether people live in a condo or an apartment or a larger home, whether they use natural gas or electricity for heating, everyone has the power to reduce their electricity consumption and lower their bills.
For example, a family living in a single-detached home with electric heating and hot water uses close to 20,000 kilowatt hours per year. If they reduced their consumption by just five per cent – about 1,000 kilowatt hours – they would not pay any more under the two-step conservation rate than they would have under the flat rate.
Saving energy is relatively easy. Turning the thermostat down one degree saves 400 kilowatt hours per year and washing clothes in cold water saves as much as 720 kilowatt hours. Hanging clothes to dry even 50 per cent of the time saves another 520 kilowatt hours.
Rebates, incentives and advice
To help all of our customers conserve, we're offering product rebates and other financial incentives through our Power Smart programs and half-price home energy audits through LiveSmart BC. The BC Hydro website is a great resource for conservation tips. People can also phone our call centre at 604 224 9376 or 1 800 224 9376, and we'll guide them through our programs.
In particular, we're reaching out to those groups who may be especially concerned about the new rate structure. We appreciate that some people will find this hard. That's why we've created an advisory panel that includes organizations representing seniors, tenants, immigrants and people with low income.
For low-income customers, we're offering free energy savings kits. We've already delivered more than 2,000 of these kits – saving a household with electric heat and water an estimated 740 kilowatt hours a year.
Among the lowest rates in North America
Even with these rate changes, BC Hydro customers will continue to pay the third lowest electricity rates in North America, after Manitoba and Quebec. Let me reiterate that BC Hydro has introduced this rate structure to encourage conservation, not to make money. Our two-step conservation rate will not generate any additional revenue for BC Hydro. In fact, we are urging our customers to buy less of our product – a relatively unique approach to sales.
By 2010, we estimate the two-step conservation rate will yield approximately 300 gigawatt hours of annual electricity savings. That's enough to power 30,000 homes. All British Columbians will benefit from those energy savings, and the additional reward of knowing that we are doing our bit to protect the environment.

What a thermostat does

What a thermostat does
Regardless of the type of heating system you have in your home,
the thermostat plays an important role in ensuring your home is
comfortable. Your thermostat determines when your heat comes
on and off, what temperature your home will be heated to, and
can help reduce your heating bills. Essentially, the thermostat is the
“brains” behind your heating system.
Types of thermostats
There are two basic types of thermostats line- and low-voltage with
a number of options for each type.
Line-voltage thermostats
Line-voltage thermostats are used to control unitary heating
systems, such as baseboard and radiant systems. The
thermostats are installed in-line (in series) with the heater, usually
at 240 volts. The full current going to the heater also goes through
the thermostat, causing it to heat up when the heater is on. This
may cause the thermostat to sense its own heat and shut off before
the room is comfortable.
Low-voltage thermostats
Low-voltage thermostats are used with gas, oil and electric central
heating systems, zone valves in hot water heating systems, and
electric unitary systems where better control is required.
Low-voltage thermostats operate at 24 to 50 volts, rather than
240 volts. They are more responsive than line-voltage, provide more
accurate control and are more adaptable to programmable controls.
Thermostat options
Whether your thermostat is line-voltage or low-voltage, there are
three general options to choose from.
Mechanical
Mechanical thermostats are inexpensive and easy to install.
Thermostats with mechanical operators (i.e. not electronic)
have either a bi-metallic strip or a vapor-filled bellows to react
to temperature change. Some are relatively slow to respond,
(particularly the inexpensive units with bi-metallic strips), which may
result in large temperature swings above and below the thermostat
set point.
Electronic
These thermostats use electronic
rather than mechanical components
to sense temperature and control
the heating system. They are
available in both line-voltage and
low-voltage models. They provide
accurate temperature control and
react more quickly to temperature changes.
Many electronic thermostats have added features such as automatic
setback and programmability. This makes them more expensive
than mechanical models.
thermostats for
efficiency and comfort
overview
Thermostats help you control your heating system for comfort and efficiency. Learn about different types of thermostats and tips
to help you select and operate a thermostat for your needs.
Programmable
Programmable thermostats automatically adjust the temperature at
pre-set times. When you pre-set your temperatures to correspond to
your daily activities you will save energy because the thermostat can
be pre-set to automatically turn down the heat at night or when the
home is empty and turn up the heat when you are home. Models
range from simple clock-like thermostats that provide day and night
temperature settings, to electronic models that let you set different
day-of-week and time-of-day temperatures.
If you have a unitary heating system, such as baseboard heaters,
the Canadian Electrical Code requires a thermostat be placed in
each room. A programmable thermostat in every room would be
expensive. Instead, install programmable thermostats only in large
rooms that have a great deal of activity, like a living room or family
room. This way it can be programmed to be on during active times
and turned down at times when the room is empty.
Special-purpose thermostats
Special-purpose thermostats have features designed to work with
specific types of equipment. For example, two-stage thermostats
are used for hybrid heating systems using two fuels, such as
electricity and oil, to turn on the backup heating system when the
primary system cannot cope with the demand for heat. Heat/cool
thermostats are used for homes with summer air conditioning.
Some thermostats allow you to switch on the furnace fan, from
the thermostat, to circulate the air in your home in the winter or
summer.
Selecting a thermostat
When choosing a thermostat, look for the ENERGY STAR® symbol.
ENERGY STAR qualified thermostats save energy by offering four
convenient, pre-programmed temperature settings – settings that try
to anticipate when it’s convenient for you to scale back on heating
or cooling. You can of course program the thermostat for your
particular schedule to reflect when you wake, leave and return to
your home and go to bed. At a minimum they will allow you to set
two different programs for your weekday and weekend schedules.
Others will allow you to set a different schedule for every day of
the week. Other features may include: digital, backlit displays; a
reminder when it is time to change air filters; and smart logic that
learns when to start heating so that your house is up to temperature
at the time you want it.
Thermostat location
Mount thermostats about 1.5 metres (5 feet) above the floor,
centrally located on an inside wall. Never install thermostats in areas
subject to drafts, direct sunlight or sources of heat such as warm
air registers, refrigerators, ranges or other appliances. All of these
factors can inadvertently affect the thermostat by causing it to read
the temperature incorrectly and not respond to the actual room
temperature.
Recommended thermostat settings
for heating
These are suggested thermostat settings that provide comfort and
avoid overheating. Thermostats in rarely-used rooms can be set
lower than those in major living areas.
Sitting, reading or watching TV 21° C (70° F)
Working around the house 20° C (68° F)
Sleeping 16° C (61° F)
No one is home 16° C (61° F)*
* This setting ensures the plumbing won’t freeze and provides
you with considerable savings.
Setting the thermostat back from 21° C to 16° C at night can result
in energy savings of up to ten per cent, depending on where you live.
Remember, cranking your thermostat up to 30° C, for example, will
not heat your house any faster. Your heating system will work most
efficiently if you set the temperature where you want it for long
periods of time (8 hours).

Fibre optic network

Fibre optic network to support all communications needs and future regional growth

VANCOUVER, British Columbia, July 6 --Bell Canada announced today the final groundbreaking for the laying of its fibre optic cable in British Columbia's Sea to Sky corridor. This installation marks a major milestone in the delivery of Bell's technology solution for the 2010 Winter Games. It supports Bell's and the Vancouver Organizing Committee for the 2010 Olympic and Paralympic Winter Games' (VANOC) shared commitment to building legacies to help generate future regional growth. During the 2010 Winter Games, the 120-kilometres of cable will be the backbone for all communications needs, including live broadcast feeds to more than a billion viewers around the world, Internet sharing of news stories and photos, Voice-over Internet Protocol requirements and more. Perhaps even more importantly, the installation, upon its completion will help provide local businesses and consumers with leading-edge, world class telecommunication services, products and productivity opportunities.
"While this milestone is a key part of Bell's technology solution for the 2010 Winter Games, it further showcases our commitment to investing in the connectivity and regional growth of Western Canada," said Justin Webb, Vice President, Olympic Services, Bell Canada. "At Bell, we are excited to be delivering on not just our shared promise with VANOC to build legacies for future generations and ensure the seamless staging of a Winter Games, but equally excited to enable local businesses and consumers to access powerful technology that otherwise wouldn't come to the region."
"Today, our shared vision for flawless technical execution of the 2010 Games becomes truly tangible," said Ward Chapin, Chief Information Officer, Vancouver 2010. "Every image we will see on TV, every news story filed, and all Games related data will be delivered on Bell technology. Bell's fibre build is a crucial linkage between our primary host locations connecting the communities of the Sea to Sky corridor from Vancouver to Whistler, and communicating to the world."
Scheduled for completion in November, Bell's fibre optic network will provide seamless connectivity leading up to and during the 2010 Winter Games, as well as support future communications needs like advanced broadband voice and data services delivery in local communities.
"Bell's fibre optic build has the potential to increase business and individual connectivity for the more than 70,000 people living on the Sea to Sky corridor," said Mayor Ian Sutherland, District of Squamish. "We are particularly excited in Squamish about Bell's network build as it will enable increased access to high-speed connectivity, which will be a major driver to increase local business capacity."
In addition to environmental screening, Bell consulted with eight corridor communities plus regional districts and government agencies to identify a fibre path that would minimize the footprint, leveraging portions of the pre-existing rail line, under bridges and through road crossings.
The feature technology is a fibre conduit encasing 144 individual fibre strands (each strand thinner than a piece of string) capable of 40,000 data transmissions per second.
