Cheap can be expensive, like energy

The energy market is currently one of the most dynamic. Since its liberalisation in 1997, with the first Aznar’s term in office, it has become a business for many companies that have decided to invest in energy trading, reaching a considerable turnover, taking into account the business life-cycle of the sector since then.

Today there are more than 420 trading companies located throughout the Spanish territory, whose scope varies depending on their size. Only 80 of them operate nationwide. Good judgement when choosing between this wide range is essential, even if hiring energy is a commodity and has a high cost the price is not everything.

When we talk about buying and selling energy we refer to its commercialisation. A final consumer does not buy and does certainly not sell. In colloquial term, he hires energy with one or another company. Hiring a fixed price implies generally to guarantee a price for a year. We often receive annual discounts on fixed prices, but to think that a discount on a fixed price necessarily means a lowering of our current costs in the same proportion as implying the discount itself is a mistake: on the one hand, the discount only applies on the unregulated part, the part set by the commercialisation company represents approximately between 25 and 30 percent of the bill; on the other hand, to determine the actual extent of the discount, the rate on which it will be applied should be at most the same rate we have now hired, otherwise, we could be incurring extra costs.

We have also heard about hiring indexed prices, which implies buying the energy matching the market price adding a sales fee charged by the distributor. In this case, we will not have a fixed price during one year, but our price will vary according to market fluctuations. There’s a lot to talk about this and many ways to compare, but no guarantee to have a specific price since we subject it to daily market fluctuations. So for now, if you decide to hire the indexed price we recommend to order a comparison with past prices and simulated bills, ie, asking the vendor or distributor that simulates us our recent bill with prices he would have said applied during the period we choose to compare.

Notwithstanding the above, it is important to note that, as in all sectors, not all existing deals are equally reliable. Biggest traders provide continuity, but not necessarily a low price. However, we can not choose a small one only for bid price, because the business of buying and selling is complex and any problems arising from poor management by who we hired the energy with can bring us indirect problems. It is therefore better to look for a combination of reliability and price, asking for referrals, finding out the history of the company and finding out if in the recent past has incurred problems. CNMC and BOE pages are sources of useful information.

Sernoven, cornerstone for sports centers energy efficiency

As a result of the experience accumulated on energy efficiency over 5 years, Sernoven has achieved the following excellent results in sports centers energy optimization:

  • Continuous improvement in the performance of Technical and Energy Consulting Service provided for Sports Centers; energy monitoring, changing usage habits, technical management of facilities optimization, maintenance facilities providing optimization, technical adequacy of obsolete or poorly maintained facilities, etc.
  • Through detailed analysis of telemetry data provided by each of the main equipment responsible of the sports facilities consumption, we have achieved to prioritize, according to the guideline customer, measures with less impact on investment and lower amount of savings over those of greater impact on investment and greater amount or vice versa. We reduce up to 40% in electricity bills and as much in thermal bills (gas, oil, etc.) by consulting detail, without necessarily having to take major investments or changes. It should be remembered that funding is provided against cost savings, however small may be the investment.
  • To acquire a deep understanding of the financing models that fit the reality of the sector that has made possible the implementation of energy efficiency measures that require a major investment.
  • Continually increase CUSTOMERS portfolio in this Sector.



Some important milestones:

  1. Air/water cooler replacement project with a hight efficiency cooler with heat recovery for preheating the ACS (hot water for sanitary uses) and semi-Olympic pool water. ESEER> 5 (cooling and thermal energy)

Investment = 241,000 €

Savings = 50,000 € / year

PRS = 4,8 years

  1. ACS production system replacement project of electrical resistance by high efficiency heat pumps (COP> 4)

Investment = 105,000 €

Savings = 24,000 € / year

PRS = 4.3 years

  1. Implementation of remote monitoring system (TELEMETRY) of electrical energy and natural gas consumption for trading variables and consumption habits optimization.
  2. Adequacy of variables instructions and facilities operation (ACS accumulation temperature, flow pumps, pools seasonal temperature, etc.) to optimize consumption.

Investment = 0€

Savings = 15,000 € / year

From SERNOVEN we offer all our knowledge and experience to improve the management of their facilities, to reduce energy costs and improve service quality to its users.
