An Evolving View of Energy Management (guest post by George Belich)

I have been in this industry a long time and have seen an tremendous evolution of energy management over the years. The pedal is to the metal now with technology, sustainability and education moving along at a rapid pace. So in the grand scheme of things I would like to offer a personal overall perspective how I now see energy management.

At the core of coarse are metering and sensor technologies along with sophisticated control devices. The IoT will allow for more points of data and control that we ever dreamed about 20 years ago. In another 10 to 20 years these points will be accessed by multiple systems and multiple users in real time.

The next logical process to the view are the building management and SCADA systems that interface with these devices in order to maintain an operational balance between cost effective performance and effective human environments. Equipment failure and human intervention will cause this to go out-of-balance at some point in time.

Then we introduce in solar, cogeneration, combine heat and power, wind, fuel cells, battery storage and more into the operations so now there is a different complexity to the situation. These introductions also bring the utility into the picture with policies and market programs such as Demand Response  and Demand Side Management that provide revenue or savings back to the end customers and their operators.

Now comes the data integration part of the process where the control data, metering data, utility billing data, weather data and facility information data such as occupancy, holidays, utility events, product output  and more must come together and provide analytics and actionable items. These systems are many, operate on many platforms and may be specialized in the particularly facility venue such as schools, manufacturing, office buildings and more. This is where the ‘Big Data’ of energy management begins and where the focus of understanding how to get more out of the operations and controls of the facility. And more. Used wisely  this information can help to lower your peak demands, lower your baselines and most of all lower your costs.

Now having said all of the above, how can we manage energy without managing the physical assets being monitored and doing the monitoring (ala, meters, sensors and relays). Maintenance systems have been around a while but I am not sure how much they have been used in the energy management process. Preventative and predictive maintenance of a facilities assets can be greatly enhanced with utility data so if there is a process why not use it and if there is not why not put one in place.  Faulty controls, sensors, meters and relays can cost more in the decision making process than ignoring them.

Over the last several years sustainability programs have been evolving to provide corporations more social visibility and overall view of their environmental concerns and performance. This is where the energy data and performance data provide a great deal of input. Not just on the financial side but on the Green House Gas side of the reports. Sustainability provides an additional case for energy management that did not exist several years ago.

This summary can run on with much more detail but is intended only to generate some  larger thoughts on energy management. The above drawing is a clear visual of this process and shows a size and scope of what energy management can be. These circles encompass various levels of personnel and skill sets in an organization that all must be engaged to have what could true energy efficiency. How active are you or you want to be in these functional areas?

2015: la Cina si incorona regina del fotovoltaico

China is also the biggest market for solar installing a massive 10.5GW last year but it is still does not have the largest installation base for solar. That accolade still rests with Germany which had 36.8GW of installed solar capacity at the end of 2014as opposed to China with 29.6GW. This however will change following China’s National Energy Administration (NEA) announcement this week of their goal to install 17.8GW of solar this year. This would give China an installed base of 47.4GW making them solar king in every way.

And thanks to the growth in China this year global solar installations are likely to hit 55GW this year which will put it ahead of wind, coal, gas, oil and nuclear in terms of new power generation installations. Meanwhile back in Europe and the US companies like GE, Alstom and Siemens who have dominated power generation for a hundred year have still no clear strategy for solar. As to China they were right to focus on dominating solar. Not only is it good for the Chinese economy, it is good for the environment and thanks to solar millions of people across the world who do not have access to electricity will get it. As to Germany they may not dominate the solar industry anymore but they still have world class businesses such as SMA Solar, Wacker Chemie, Von Ardenne, and research institutes such as the Fraunhofer. And they have lots of zero marginal cost solar in their system which is driving huge changes and innovations in the power markets.

E’ nata: pubblicata la norma ISO 50002

Ultima nata della famiglia 50000 la norma ISO 50002 descrive le modalità di esecuzione degli energy audits, fondamentali per ogni intervento efficenziale.

Abstract

ISO 50002:2014 specifies the process requirements for carrying out an energy audit in relation to energy performance. It is applicable to all types of establishments and organizations, and all forms of energy and energy use.

ISO 50002:2014 specifies the principles of carrying out energy audits, requirements for the common processes during energy audits, and deliverables for energy audits.

ISO 50002:2014 does not address the requirements for selection and evaluation of the competence of bodies providing energy audit services, and it does not cover the auditing of an organization’s energy management system, as these are described in ISO 50003.

ISO 50002:2014 also provides informative guidance on its use.

L’energia è strategica: approvati i decreti Golden Power

Sono stati pubblicati nella GU del 6 giugno i DPR 85 e 86 sui golden power, ossia  i poteri speciali che spettano al Governo sugli assetti societari dei soggetti che operano nei settori della difesa e della sicurezza nazionale, nonché nei settori dell’energia, dei trasporti e delle comunicazioni.

Si alza la testa o si dà veste ufficiale alla sudditanza nei confronti delle multinazionali? ahhhh, saperlo…

Il nuovo standard formativo per l’installazione e la manutenzione di impianti FER

La Conferenza delle Regioni e delle Province autonome, nella seduta del 24 gennaio, ha approvato un documento sullo standard formativo per l’attività di installazione e manutenzione straordinaria di impianti energetici alimentati da fonti rinnovabili. Saranno adesso le Regioni a fornire le indicazioni operative per predisporre le conseguenti offerte formative.

Parte quindi il cosidetto “patentino delle rinnovabili” che sarà strutturato in un modulo di base e 4 moduli di specilizzazione:

– impianti a biomasse

– pompe di calore

– solare termico

– solare fotovoltaico

Interesserà installatori e manutentori di impienti per la produzione di energia da fonti rinnovabili.
