Expansion of Market Share for Gas Utilities

Danish gas utilities have successfully employed the positive aspects of solar water heaters in their marketing strategies, to increase market share of natural gas. One Danish utility, Naturgas Midt-Nord, has attributed a 60% increase in gas sales (878,000 m³) (see ref 2) to their marketing campaign, which combines solar water heating and natural gas. The competitive positioning is that the solar-gas combination is a more environmentally friendly package compared to oil or electricity.
 

Achieving CO2 Reduction Targets and Creating Corporate Goodwill

The Dutch utility, Nuon, has already facilitated the installation of approximately 7,500 solar water heaters through a well-developed project approach. This on-going venture provides utility customers with reliable, cost-effective water heating by combining solar energy with the base fuel. Each installation contributes around 300 kg in annual CO2 reductions.

Nuon has also benefited by taking a leadership position with respect to emission reduction targets, and has succeeded in turning this issue into a winning business strategy, promoting public goodwill for the utility. As a direct result of this programme, the utility has received extensive positive publicity both locally and internationally.
 

New Customer Choices

Many utilities are finding that their customers are asking for new product and service choices. These customers are motivated by the increased expectations that accompany deregulation and competition, as well as by an increased understanding of environmental issues. There are many markets where customers have expressed a strong desire for "green" energy products. Some customers demonstrate a willingness to pay more for "green" energy (21%, MORI opinion poll (see ref 3), UK; 11%, Ontario Hydro, Canada (see ref 4)). However, significantly more customers express a desire for "green" energy if the price is not higher (65%, MORI opinion poll, UK; 30%, Ontario Hydro, Canada).
 

Retailing Opportunities

In the UK, some of the recently deregulated energy companies have added solar water heaters to their retail product mix. These utilities use their billing service to offer customers energy-related products such as solar water heaters. Some utilities also offer financing packages to assist sales growth.
