Immediate Positive Cash Flow from Energy Efficiency Using Building Upgrade Finance

Energy efficiency initiatives and behind-the-meter solar PV installations are usually the most cost-effective way of reducing energy costs. Implementing these initiatives result in larger and more sustainable cost savings than simply negotiating with energy retailers for sharper prices or doing a Power Purchasing Agreement (PPA) with a third party whether you are an SME or a large business.

However, there are several significant barriers that businesses face in implementing energy efficiency measures and investing in solar. […]

How To Reduce Electricity Costs – Part 3

In the first article of the four-part series, we looked at how the cheapest electricity is the electricity that you do not use and the many opportunities to capture the low hanging fruit of energy efficiencies.

In the second article, we looked at how savings can be achieved by purchasing electricity at wholesale market pool prices and then achieving even further savings by employing Demand […]

How To Reduce Electricity Costs – Part 2

In the previous article on reducing electricity costs we looked at energy efficiency and the fact that the cheapest electricity is the electricity that you don’t consume.

In this article we will look at how to pay less for the electrons that you do consume.

The article is based on Chapter 13 (Step 6) of my book “Power Profits – A Comprehensive 9-Step Framework for Reducing Electricity Costs and Boosting Profits.

Retailers bundle up electricity products […]

How To Reduce Electricity Costs – Part 1

We all know that electricity prices have escalated dramatically over the last couple of years. But did you know that it is possible to offset these increases and even achieve cost reductions in the face of increasing retail prices?

Electricity bills are composed of:

  1. Energy charges (the cost of the electrons that you consume)
  2. Network charges (the cost of the supply infrastructure required to deliver the electrons to you)
  3. Retail supply charges (the cost of the […]

South Australian Wholesale Electricity Price Review 29th July – 4th August 2018

Pool prices fell last week due to strong wind generation throughout most of the week and some negative half-hour prices dragging the average down below the median price.

The average price was a relatively low $61.09/MWh with the median price being $65.13/MWh. The average was lower than the median due to several half-hour periods of negative prices, the lowest of which was -$366.10/MWh. There were no half-hour prices above $300/MWh and […]

Employing Demand Response To Reduce Electricity Costs

With the recent recommendations of the ACCC to implement a demand response mechanism to “promote competition” and “not allow retailers to limit the ability of customers to engage a third party demand response provider” I thought that I would share excerpts from Chapter 13 of my recent book Power Profits – A Comprehensive 9-Step Framework For Reducing Electricity Costs and Boosting Profits.

This Chapter discusses how end users have the option not to accept plain […]

South Australian Wholesale Electricity Price Review 22nd – 28th July

Prices increased in the week of 22nd – 28th July due to one high price spike on Saturday the 28th when wind generation and imports from Victoria dropped to almost zero during the morning high demand period. High-cost Open Cycle Gas Turbine Generation (OCGT)  and diesel generation were required to meet demand during this period. The average price was $93.10/MWh compared with the prior week of $76.20/MWh.

Figure 1 shows a box […]

South Australian Wholesale Electricity Price Review 8th – 21st July

This week’s blog covers the last two weeks electricity price action as I was “curtailed” last weekend with higher demand elsewhere.

The prices during the week of the 8th-14th July were significantly higher than previous weeks due to a scheduled outage of a transmission line connecting the South East of the State to the rest of South Australia on the 9th July.  This […]
