This applies to Bulk Power Consumers like Estate,  Hospitality facilities, Corporate Facilities, Religious Centres, Event Centres etc

You can save 10-50% on your electrical energy services cost if you invest in power factor correction. See mathematical analysis later in this piece. 

Breaking it down literally, normal electrical operations is at 0.8pf. Best practices is from 0.9pf.  Your Kwh rate at 0.9pf is probably around N40, at 0.8pf kwh is probably N49 already indicating you pay an extra N9 per kwh for operating at 0.8. When you operate lower at 0.7pf,  you probably pay extra N15 and at 0.6pf,  you could be paying extra N22 per kwh. 

Check your bill for your last total KWH and you will see the need to modify your electrical system. 

Whenever an Electrical System load is predominantly Inductive (sorry for another electrical Jagon) meaning you have more of load contents like Airconditioners which is over 75% of the load content, lift equipment, hand driers and various pumps and you don't have a power factor correction equipment incorporated, you are automatically spending 10-50% more on your energy budget whether it is public power, or generator power.

Understanding Power Factor Correction (PFC) is the first step towards experiencing the many benefits associated with good power factor. Poor power factor means poor electrical efficiency and in turn, the lower the power factor, the higher the apparent power drawn from the distribution network.

One side effect of this is higher capital expenditures and operating costs for distributors, which in many cases is passed on to the consumer in the form of higher tariff rates.

Why Promote this product after the huge investment in power distribution equipment and cabling. 

The answer is that if your facility is currently not having a power factor corrector, you are spending at least 8 to 10% more in your power deployment in a normal system and could be 20 to 50% in a very dysfunctional electrical systems with old lift, old air-conditioning, old pumps,  old factory equipment etc. 

Can you now imagine the savings monthly and yearly? 

For example:

A typical Bank branch is about 100kW or 125kVA at 0.8pf and 105.3kVA at 0.95pf. The kVA Being 133.3 at 0.75pf. 

In view of load profiling the bank may be off peak from 7-9am at 50kw,  peak 80kw from 9-3pm, off peak 50kw from 3-7pm and be on 27kw over night till 7am. 

All adding up to 904kwh daily. At 0.8pf,  the bank will pressure their profit margin by N9 penalty charge x904kwh  being N8,136.00 daily, about N253,000 monthly and about N3million yearly. 

For a technical approach see below. 

100 kW load at a PF of 0.8= 75 kVAr 
100 kW load at a PF of 0.9 = 49kVAr 

The extra kVAr drawn from the supply is:

75kVAr – 49kVAr = 26 kVAr
26 x Npenalty charge per hr x 24hrs= Npenalty perday

A typical bank branch office with 100kVA load profile may be charged this extra monthly unless the system is improved with adequately sized Power Factor Corrector. 

Assume the Power factor correction unit will cost installed about N60,000 per kVAr
Therefore 26.0 kVAr x N60000 = N1,170,000
Payback period = N1,560,000 divided by N253,000 = about 6months.

In about 6 months, the cost for power factor correction is recovered and any further penalties are avoided for the life of the electrical installation. Any further savings then become profits that add to the company’s bottom line.

Imaging this as savings or additional profit in over 100 branches.

Note: This example is for illustration purposes only. Actual savings will vary from installation to installation.

PFC is a means of providing compensation locally to reduce this excess power draw which can result in electricity bill savings, reduced system losses and optimal utilization of energy resources and transformer capacity.

 HIWORKS can help size, commission and maintain your chosen PFC system. With the flexibility to suit your application requirements.
We shall also require to carry out your electrical audit to see the energy use trend and use some of the information to develop the power factor capacity for the power system.
We shall be available for further clarification of the development.

RFI - REQUEST FOR INFORMATION

Search Wikipedia

This article is about the business practice. For the motion in parliamentary procedure, see Request for information (parliamentary

A request for information (RFI) is a standard business process whose purpose is to collect written information about the capabilities of various suppliers. Normally it follows a format that can be used for comparative

An RFI is primarily used to gather information to help make a decision on what steps to take next. RFIs are therefore seldom the final stage and are instead often used in combination with the following: request for proposal (RFP), request for tender (RFT), and request for quotation (RFQ). In addition to gathering basic information, an RFI is often used as a solicitation sent to a broad base of potential suppliers for the purpose of conditioning suppliers' minds, developing strategy, building a database, and preparing for an RFP, RFT, or RFQ. [1]

The ubiquitous availability of the Internet has made many government agencies turn either to state-run or vendor operated websites which provide listings of RFIs as well as RFPs and RFQs. Many allow vendors to sign up at no charge to receive e-mails of requests either generally or for specific categories of product or service for which there is an interest. In some cases, the entire process is done on-line with responses as scanned documents or PDF files uploaded to the server; in other cases, or for legal reasons, a response must be sent in hard copy form and/or on CD/DVD disc or flash drive by mail or delivery service.

The RFI procedure is used in the construction industry in cases where it is necessary to confirm the interpretation of a detail, specification, or note on the construction drawings, or to secure a documented directive or clarification from the architect or client that is needed to continue work.

An RFI raised by the general contractor that has been answered by the client or architect and distributed to all stakeholders is generally accepted as a change to the scope of work unless further approval is required for costs associated with the change.

It is common and accepted practice for a subcontractor or supplier to use an RFI to state his/her concern related to the omission or misapplication of a product, and seek further clarification of the building owner's intended use or the building official acceptance of the specified product. It is also acceptable for the subcontractor to use an RFI to call attention to an inferior product that may not meet the building owner's needs, and use his/her expertise to recommend the better/correct product.

If used as described above it is a very effective tool in helping a construction project move along efficiently. There are circumstances where the use of RFI's is abused, and simply creating paper to justify unwarranted claims. Such a circumstance occurs when RFI's are continually being issued when the information is clearly shown on the documents. In this case, either the person reading the drawings is working outside of the scope of their capability, or the intent is to generate paper to help support what might otherwise be an unjustifiable claim.

RFQ- -REQUEST FOR QUOTATION

Search Wikipedia

A request for quotation (RFQ) is a standard business process whose purpose is to invite suppliers into a bidding process to bid on specific products or services. RFQ generally means the same thing as IFB (Invitation For Bid). [1]

An RFQ typically involves more than the price per item. Information like payment terms, quality level per item or contract length may be requested during the bidding process.

To receive correct quotes, RFQs often include the specifications of the items/services to make sure all the suppliers are bidding on the same item/service. Logically, the more detailed the specifications, the more accurate the quote will be and comparable to the other suppliers. [original research?] Another reason for being detailed in sending out an RFQ is that the specifications could be used as legal binding documentation for the suppliers.

The ubiquitous availability of the Internet has made many government agencies turn either to state-run or vendor operated websites which provide listings of RFQs as well as RFIs and RFPs. Many allow vendors to sign up at no charge to receive e-mails of requests either generally or for specific categories of product or service for which there is an interest. In some cases, the entire process is done on-line with responses as scanned documents or PDF files uploaded to the server; in other cases, or for legal reasons, a response must be sent in hard copy form and/or on CD/DVD disc or flash drive by mail or delivery service.

The suppliers have to return the bidding by a set date and time to be considered for an award. Discussions may be held on the bids (often to clarify technical capabilities or to note errors in a proposal). The bid does not have to mean the end of the bidding. Multiple rounds can follow or even a reverse auction can follow to generate the best market price.

RFQs are best suited to products and services that are as standardised and as commoditised as possible, as this makes each supplier's quote comparable. In practice, many businesses use an RFQ where an RFT or RFI would be more appropriate. [2]

An RFQ allows different contractors to provide a quotation, among which the best will be selected. It also makes the potential for competitive bidding a lot higher, since the suppliers could be quite certain that they are not the only ones bidding for the products.

Requests for quotations are most commonly used in the business environment but can also be found being applied to domestic markets.

UPS Recovery & UPS to Inverter Upgrade Between 500VA(W) &10,000VA (W)

Be Pennywise & Recover Your UPS for as low as Quarter the Price of a new one or Upgrade to Inverter and Do More for Longer Hours

The current economic melt down have triggered a higher cost for many home and office appliances.

This got us to think of other ways to satisfy our unavoidable home and office needs.

Such is recovery of the old UPS as against ordering a new one. The lowest Ups capacity used to be below N7000 but now is about N12,000 for good brands. The same price upgrade applies to stabilizers.

At Hiworks, we have established a Maintenance Department with the required competence, leveraging on our experience with inverter system Management, to provide recovery and upgrade services for UPS Systems.

Our research finding over the years indicated to us that 90% of packed up UPS have poor rectification circuitry from manufacturer and the second being battery failure.

Both can be resolved with as low as N4000 and in addition an upgraded rectification and a more efficient UPS appliance.

There is however, a troubleshoot charge of N2500 for up to 5 UPS Systems  for any location within Lagos Island and Mainland.

We can also upgrade your UPS to an Inverter system that will deliver more time at full charge.

We have Limited our focus to UPS,Inverter and Stabilizer in these office and home support services from popular demand.

We look forward to getting service request soon

Thank you.
